Ruban, Luidmila. "LANDSCAPE DIVERSITY OF THE NATIONAL DENDROLOGICAL PARK "SOFIYIVKA" OF THE NATIONAL ACADEMY OF SCIENCES OF UKRAINE." Current problems of architecture and urban planning, no. 63 (April 14, 2022): 87–99. http://dx.doi.org/10.32347/2077-3455.2022.63.87-99.
Full textAbstract:
The article reveals the landscape diversity of the historical garden and park landscape – the National Dendrological Park "Sofiyivka" of the National Academy of Sciences of Ukraine in the city of Uman, Cherkasy region, founded in 1796-1800. In the classification of landscape gardening landscapes, developed by the Ukrainian landscape architect, doctor of biological sciences Rubtsov L.I., 6 types of landscapes are distinguished. The landscape of the NDP "Sofiyivka", as an object of landscape gardening art, belongs to the group of anthropogenic landscapes and is classified as a cultural, recreational, slightly modified landscape (historical core of the park) and modified landscape (Grekova and Lesnaya beams). On the territory of the arboretum, all types of landscape gardening landscapes are presented: forest, park, meadow, garden, regular, alpine landscapes. Most of the historical core of the park is occupied by the park landscape; the forest landscape has been preserved closer to the boundaries of the arboretum. The meadow landscape exists both at the bottom of the beams and in elevated places, such as on the Fungus lawn. The garden type of landscape is presented in the English Park, created in 1890 91 by Pashkevich V.V. and in a series of new monocultural gardens (of lilacs, magnolias, maples, chrysanthemums, dahlias, daylilies, hosts, etc.). The Kamyanka River is an alpine (or mountainous) type of garden and park landscape due to natural granite outcrops and shifted boulders. Examples of the regular landscape are the amphitheater, alleys, greenery protection strips, as well as the regularly planned area of the new entrance to the arboretum from the street Kyivskaya with a fountain and a rosary. These garden and park landscapes of the arboretum "Sofiyivka" are the most valuable natural ecosystem formations within the arboretum, which must be preserved and maintained accordance with the strategic principles of ecological unity and reproduction of natural resources.

Full textAbstract:
This paper outlines the history of the SFA Arboretum's effort to establish a campus-as-arboretum at the university. In 1996, the participants created a robust Geographic Information System (GIS) for the campus forest based primarily on a 1993-95 campus mapping and tree inventory project in the 144-acre main core of the campus (Wilson to North St.; College to Starr). The project served as the MS thesis of Susan Perkins. In brief, the campus model reveals a pine-dominated Type 2 forest (one rapidly approaching maturity), difficult campus hydrology issues, and a landscape low on diversity with 68 species represented. In 1996, the Arboretum's AutoCAD® map and Excel® tree data files were integrated into the College of Forestry Unix-based ArcInfo® platform. This now provides full GIS capabilities for landscape planners. The resultant maps based on user queries reveal a robust vegetation analysis and management tool. In 1997, the SFA administration, Physical Plant, Grounds, College of Forestry, and SFA Arboretum initiated a “campus beautification” funding campaign. The SFA Arboretum will play a key role in building unique, documented, and mapped woody ornamental collections for the campus. This provides a unique opportunity in the South for long-term Zone 8 woody plant evaluation in a high-visibility and “perpetual” landscape.

Full textAbstract:
Why do people visit the grounds of a botanical garden or arboretum? What draws them to that “experience of nature”? What can we do as horticulturists, landscape architects, and educators to make garden areas more appealing and fulfilling to visitors? The Prairie Interpretive Committee of the Minnesota Landscape Arboretum asked these questions in 1991 as it convened to analyze the current and future status of the Arboretum's Bennett/Johnson Prairie. To understand visitor usage and needs, Arboretum members were surveyed about frequency of visits, reasons for visiting, specific visitor services, and suggestions for improvements. Among the 151 responses, the major reasons for visiting were the pleasures of walking, observing, and being at peace. “Open”, “wild,” and “natural” were common key words. There was keen interest in native plants and their historical role as well. Sitting areas, maps, path markers, plant labels, and self-guided tours were the primary requests for improvement. A high percentage found the demonstration area interesting and useful. The Interpretive Committee used this research to guide the landscape architect, create a brochure, and develop an integrative master plan for the prairie area.

Full textAbstract:
The Holden Arboretum, established in 1931, is the largest arboretum in the United States. Its mission is to promote the knowledge and appreciation of plants for personal enjoyment, inspiration, and recreation; for scientific research; and for educational and aesthetic purposes. Of the Arboretum's 3100 acres, 800 acres support collections and display gardens, while the balance comprise natural areas. The collections include nearly 8,000 accessions from 76 plant families; about 700 plant species, some rare or endangered, occupy the natural areas. The education component of the mission connects the Arboretum with the public through school programs, classes, horticultural therapy, and seasonal internships. Two research fellowships are also available. The Holden Arboretum has expanded the research emphasis. The David G. Leach Research Station, part of the Arboretum since 1986, focuses on rhododendron and magnolia breeding and research. Built in 1993, the Horticulture Science Center is a modern research and production facility able to more fully implement and support a broad range of formal horticultural research. The main objective of the research program is to develop superior woody ornamentals for the landscape through hybridization. Additional research emphasizes reproductive biology and using biochemical markers (isozymes and RAPDs) to answer basic questions about the genera under study (Aesculus, Hamamelis, Cercis).

Full textAbstract:
Purpose. To analyze the taxonomic and varietal diversity of the collection of spicy plants of the Syrets Arboretum, evaluate their decorative qualities and determine the directions of use in landscape design. Methods. The subject of the study is spicy plants grown on the territory of the Syrets Arboretum, which are a part of the collection of open ground plants. The species and varieties of this group of plants were introduced in the arboretum from 1949 to 2021. In the process of research, methods of analysis and synthesis, comparison and generalization of information were used. Results. It has been established that the collection of spicy plants of the Syrets Arboretum includes 69 taxa belonging to 33 genera, 12 families. There are 52 species and 25 cultivars among them. The largest number of representatives are in the families Lamiaˆceae – 32 taxa, Amaryllidaceae – 11 taxa and Asteraceae – 9 taxa. The life forms of spicy plants are represented by woody (19 taxa) and herbal plants (50 taxa, of which 10 annual, 2 biennial, and 38 perennial forms). The traditional fields of application of spicy plants are food, medicine (pharmacology) and perfumery. In addition, their decorative varieties and cultivars are used to create landscape compositions. In particular, on the territory of the Syrets Arboretum, spicy plants are the compositional basis of the thematic “garden of spicy aromatic plants”, they are used as elements of classic flower beds and summer compositions, thematic compositions (national and pharmacy gardens, vegetable flower beds), alpine slides and rocky gardens, etc. Conclusions. Many years of experience in landscape design and creation of floral arrangements in the Syrets Arboretum showes that spicy plants are an important element in all types of tested decorative compositions. It is revealed that out of 69 spicy plants that grow on collectible plantings of the Sirets Arboretum, 51 have decorative qualities and are used as decorative-floral and decorative-deciduous species. The taxonomic and varietal variety of spicy plants has considerable potential for breeding work and creation of highly decorative landscape compositions of various purposes. Due to the availability of different life forms and biomorphological features, it is advisable to use spicy plants in different types of plantations for decorative gardening and landscape design.

Full textAbstract:
The SFA Arboretum is evidence that small horticulture programs can capitalize on what's right outside the back door of the building. Initiated in 1985 as a lab project in a landscape plant materials course on the south side of the Agriculture building, the collection has grown to over 3000 taxa displayed in a ten-acre public garden setting. The Arboretum's mission is to 1) promote the conservation and use of native plants, 2) evaluate “new” landscape plant materials, and 3) serve as a living laboratory for students in Horticulture, Agriculture, Biology and Forestry. Funding improvements in the last two years and the creation of a Board of Advisors and a Volunteer Corps organization has addressed problems in routine landscape maintenance and getting “new” garden developments off the ground. A “Plants with Promise” program acquires, tests, propagates, distributes and promotes superior “new” woody plants. Outstanding performers include Bignonia capreolata 'atrosangainea', Campsis grandiflora, Cinnamomum chekingensis, Euschapis japonica, Scuttelaria suffretescens 'pink', Sinojackia rehderiana, Taxodium mucronatum, Viburnum propinquum, various Styrax species and varieties, several Michelia species, Illicium henryi, three Mexico oaks, and many others. AutoCAD maps and a plant inventory database tracks plant location and acquisition data. A just-completed GIS-based analysis of the university forest paves the way for a campus-as-arboretum effort. The premise of this paper is that high-visibility, easy-access display/evaluation gardens offer Horticulture Departments the opportunity for enhanced student recruitment, community involvement, external funding, environmental education, and the potential for significant contributions to the nursery industry.

Full textAbstract:
The SFA Mast Arboretum began as a landscape plant materials class project on the south side of the Agriculture building in 1985. In 2000, over 20 theme gardens now occupy 18 acres. The garden is computer mapped and an accessioning system is in place. Theme garden developments include daylilies, herbs, a rock garden, a xeriscape, plants for shade, wetland, and bog conditions, a line of vines, an Asian Valley, conifers and hollies, and numerous gardens that trial and display herbaceous perennials. Recent developments include a children's garden and, the biggest project to date, an 8-acre SFA Ruby Mize Azalea garden, with a grand opening in Apr. 2000. Theme gardens are utilized to display collections. Significant assemblages include Rhododendron (400 cultivars and selections), Acer (168 cultivars), Camellia (210 cultivars), Loropetalum (18 taxa), Cephalotaxus (43 taxa), Magnolia (47 taxa), Abelia (37 taxa), Ilex (73 taxa), and others. Plant performance and observational information is recorded. Second author Grant has numerous plant introductions in the past 5 years, many that are well represented in the nursery industry and recognized by TAMU's Coordinated Educational and Marketing Assistance Program (CEMAP) as “Texas Superstar” promotions (trademarked). SFA Mast Arboretum plants are promoted via distributions, trade articles, and the Arboretum's website: www.sfasu.edu/ag/arboretum.

Full textAbstract:
The mission of the SFASU Arboretum is to promote the conservation, selection, and use of the native plants of Texas and to encourage diversity in the urban landscape philosophy of the region. A decade since its inception, the 10-acre arboretum features many uncommon, unusual, and difficult-to-find species and cultivars, many deserving greater use in the region. The living collection has been acquired through botanical gardens, arboretums, private collections, the nursery industry, and expeditions. The list of promising plants that have surfaced includes many that are not easily available in the trade. The issues involved in woody and herbaceous plant evaluation include computer mapping and record keeping constraints, the long-time frame for evaluation with many woody plants, and difficulties in propagation. The arboretums's plant acquisition policy and record keeping and computer mapping system is currently tracking more than 2500 taxa in the living collection. An overview of the first decade of plant performance and a strategic plan for acquisition, propagation, evaluation, distribution, and promotion are presented.

A survey of gardeners in Minnesota found they get their information from friends and garden centers. Older gardeners were less likely to use the Internet. The highest interest was indicated for annuals, perennials, and containers, followed by trees and shrubs. Most participants had not attended a gardening class in the past year and indicated they learn best from talking with friends. Publications are of interest to gardeners, and they highly value color photos and illustrations. The University of Minnesota and Minnesota Landscape Arboretum were perceived as significantly more credible and trustworthy than garden centers, and participants felt these institutions should provide educational programs, even if survey respondents were not participating in these programs. About half the participants were not able to comment on the level of bias of the university and arboretum, and other traits (credible, trustworthy, expert, and knowledgeable) were unknown to one-third to one-half of the participants. Participants knew more about these traits for garden centers and home stores. Participants in this survey indicated they look for convenient sources of gardening information and, although many felt the land-grant university and arboretum were highly credible and knowledgeable, they were still more likely to use other sources for their gardening information. This poses a challenge to universities and arboreta to use new ways to reach gardeners.

Botanic gardens and arboretums are being set up around the world to help create special collections of plants for the purpose of introduction, conservation of biodiversity and enrichment of the plant world, as well as scientific and educational activities, which, in addition, help in the fight against climate change. In our project, for the first time, it is proposed to create a specialized nectar-bearing arboretum, called the nectar-bearing landscape area of continuous flowering or a nectar forest, which, in addition to the above functions of ordinary arboretums, will also have economic value in the form of creating a universal food base for efficient beekeeping in our region. The first nectar forest with an area of about 18 hectares will be created in the south of the Nurimanovskiy district of the Republic of Bashkortostan near the village of Kyzyl-Barzhau. It is planned to plant a nectar forest, which will consist of 50% different species and forms of lindens, 20% willow and maple species, and the share of all other melliferous woody plants will be 30%. The total number of taxa of the genus Tilia L. (linden) will be 24; it is also planned to use at least 6 species of maple and 12 species and forms of willow. The total number of tree taxa involved will be at least 100. The total duration of flowering of honey plants in the nectar-bearing landscape area of continuous flowering with the participation of the entire population of planned taxa will be at least 193 days (from April 13 to October 24), which will cover the entire beekeeping season in the selected region. The organization of a nectar forest with high species diversity will increase the amount of honey obtained per unit area by at least 114% more compared to Tilia cordata plantations. Increasing the diversity of the forage base and its availability throughout the season will improve the health and stress resistance of bee colonies and increase the brood. In addition to honey production, the nectar forest will also perform the traditional functions of arboretums: scientific, educational, environmental, aesthetic, and recreational. Since the laying of a new arboretum involves the cultivation of a young forest that absorbs carbon dioxide most efficiently, the nectar forest can be used as one of the sites of the Eurasian carbon polygons, which is planned to be created in the Republic of Bashkortostan.

The Minnesota Landscape Arboretum has been educating urban youth in a garden setting through the Children's Garden in Residence program located in Minneapolis, Minn., for 20 years. The program partners with community groups to teach pre-K to 4th grade students about the wonders of science and nature. The program presently educates between 100 and 120 children each summer. In addition to serving more children, the program curriculum and activities have evolved through the years, developing, trying, redesigning, and trying again curricula to meet the needs of urban children. The result of this process is a program that emphasizes hands-on, garden-based lessons in science, nutrition, and art. We are in the process of documenting the curricula used in the program. This paper will discuss the history of the program, highlight a few units used at the different grade levels, and discuss the documentation process.

Formative evaluation (pretesting) can lead to better working exhibits in public gardens. While many botanical gardens and arboreta will attest to the importance of using formative evaluation, it has not been used to develop exhibits for consumers with diverse disabilities. At the Clotilde Irvine Sensory Garden of the University of Minnesota Landscape Arboretum (Chanhassen, Minn.) we are interested in developing exhibits that meet the needs of audiences with disabilities. To that end in 2000, four comprehensive interpretive exhibits were pretested before the final exhibits were installed within the Clotilde Irvine Sensory Garden to determine the exhibits ability to teach concepts to all regardless of disability. The evaluation indicated these exhibits were physically accessible, but needed attention in specific areas to enhance their inclusiveness.

Protected man-made parks of Ukrainian Polissya, created in the period of postmodernism, are conservation oriented, historical, cognitive and educational objects. Landscape design is a synthesis of traditions and new transformation trends. On the territories of protected man-made parks, natural existence and distribution of rare species are maintained, endangered and vulnerable species are protected, hydrological functions are improved, and valuable landscapes are preserved. Concentrated in Rivne region, five parks, which have the status of complex natural monuments of local significance, were created in Ukrainian Polissya in the 1960s. According to the results of the analysis of formation and development history, the transformation of complex natural monuments (CNMs) of Ukrainian Polissya for a period of over 60 years is shown. CNMs have a simple planning structure of the following types: cross-shaped ("Vysotsky Arboretum"), star-shaped ("Bilsky Arboretum", "Sarny Arboretum"), loop-shaped ("Rokytne Arboretum"), and combined ("Tryputnyansky Park"). Of the three parks with regular planning, the biggest change can be observed in the complex natural monument "Bilsky Arboretum". This is due to the growth of hedges, which are not currently formed, and to the violation of the boundaries of meadows, where self-seeding plants appear. The dendroflora of five man-made parks is represented by 157 species, which belong to 19 orders, 32 families, and 81 genera, with 111 of them being included to the IUCN Red List. In two parks during their existence, there was an increase in the number of species by 11-50%, with the number of rare tree species amounting to 50-71%. In three parks under the influence of anthropogenic and ecological factors, there was a decrease in dendrodiversity, with 55-81% of species of woody plants remaining; аmong them 71-75% are rare tree species. Protected man-made areas of Ukrainian Polissya are valuable objects that need to be further developed and protected, whereas their collections of woody plants replenished and maintained.

Elms from China offer good possibilities as urban trees because of good levels of disease resistance, stress tolerance, and aesthetic appeal. Success in obtaining seeds of little-known elm species has made possible the assembling of a large collection of elms at the Morton Arboretum. Assessment of the potential of these elms as urban trees is proceeding. Some of the elms from China are producing flowers, giving opportunities for hybridization. Several recently received species are new to North America, with arboricultural qualities and urban-use potential virtually unknown. Descriptive information has been obtained from a translated monograph on elms of China.

Abstract ‘Apalachee’, ‘Comanche’, ‘Lipan’, ‘Osage’, ‘Sioux’, and ‘Yuma’ are the first intermediate growth habit Lagerstroemia indica L. × L. fauriei Koehne cultivars to combine mildew resistance, an array of spectacular exfoliating bark colorations, and a range of flower colors. Seven previously released U.S. National Arboretum-released L. indica × L. fauriei mildew-resistant cultivars, ‘Muskogee’, ‘Natchez’, ‘Tuscarora’, ‘Tuskegee’, ‘Biloxi’, ‘Miami’, and ‘Wichita’ are vaseshaped, outward-arched, small trees that can be expected to mature at 7 to 10 m high (4–6, 8); while four others, ‘Acoma’, ‘Hopi’, ‘Pecos’, and ‘Zuni’, are semi-dwarf growth habit cultivars that will ultimately mature at heights <3 m high (7). ‘Apalachee’, ‘Comanche’, ‘Lipan’, ‘Osage’, ‘Sioux’, and ‘Yuma’, with mature heights <5 m, bridge the landscape growth habit gap between the upright, small trees and the compact, semidwarf cultivars. With the introduction of these six cultivars, the U.S. National Arboretum Lagerstroemia breeding project has introduced 23 unique, distinct, and noteworthy cultivars for the nursery industry, landscape architects, and home gardeners alike (1–3).

Green space has a vital role in the community’s health and well-being. Forest bathing is an effective method of enjoying the forest atmosphere through physical activity or relaxing in a forest landscape. However, until now, no one has declared the benefits of forest therapy in Indonesia. This study clarifies the physiological and psychological effects of walking in a campus landscape. This research was conducted using experimental methods through physical activity survey, self-report questionnaires, Visitor Employed Photography (VEP), and automatic classification based on the image annotation API. The experiment was conducted in a park and an arboretum, and thirty-two young university subjects were tested. The participants walked for fifteen minutes on walking routes and district roads. Their blood pressure was measured before and after walking, and their heart rate was measured continuously. During the walk, the subjects took photographs of striking scenes using the Visitor Employed Photography method. Profile of Mood States (POMS) and State-Trait Anxiety Inventory (STAI) were used to evaluate the psychological responses. Walking in the campus landscape resulted in a lower heart rate, less negative moods, and less anxiety than walking on the district road. Out of 837 photographs, 45% were taken from the Academic Event Plaza, 41.5% from the Arboretum, and the remaining 13.5% from district road, Jalan Raya Dramaga. Two main groups of campus green spaces included man-made landscape consisting of road surface, buildings, plant organs, stairs, and terrestrial plants; and natural landscape consisting of sky, trees, flowers, clouds, and plant community. This study found that walking in campus green space induced physiological and psychological health benefits and prominent landscape elements supported the green campus.

Horticultural enrollments have fallen since the late 1970's and faculties are scrambling to find new ways to creatively finance educational and outreach programs. The Stephen F. Austin State University Arboretum was sanctioned by the administration in March, 1987. Eight acres of land that lie on LaNana creek are directly associated with the Agriculture building and horticultural facility. Gardens that feature a wide range of rare, unusual, and untested landscape plants are being developed by students, volunteers, and a mix of outside monies. The history of a City/SFASU project to develop a three mile LaNana Creek trail will be described. A cooperative effort with the Herb Society of Deep East Texas, a 121-acre conservancy easement project, and Asian vegetable studies are currently under the arboretum umbrella.

Full textAbstract:
Plantings’ ornamentality is an important aspect of the aesthetic appearance formation of urbanized landscapes. In urban ecosystems, trees and shrubs are often exposed to high stress levels that shortens their lifespan and reduces ornamentality. Plant introduction is one of the methods of enriching the assortment with resistant species. The aim of the research was to comprehensively assess the ornamentality degree of North American introduction tree groups from the genetic collection of the All-Russian scientific research Institute of Fruit Crop Breeding (VNIISPK) arboretum and to give recommendations on improving their composition. Research was carried out in 2013-2019, taking into account the dynamics of changes in decorative qualities during the year. Throughout the year, landscape compositions showed peaks of ornamentality in the same seasons of the year (May, September). To give dynamism to groups in the summer period, it is recommended to plant Spiraea douglasii in the 1st group; in composition 2 — Hydrangea arborescens and two varieties of Physocarpus opulifolius: ‘Darts Gold’ and ‘Summer Wine’. Graphics of ornamentality degree changes of landscape groups are recommended to be used when drawing up landscape groups for various purposes to ensure their ornamentality during either an entire year or a certain period.

Full textAbstract:
Abstract ‘Biloxi’, ‘Miami’, and ‘Wichita’ are the first introduced tree growth habit Lager-stroemia indica L. × L. fauriei Koehne cultivars that combine mildew resistance, dark trunk bark coloration, and a range of flower colors. Lagerstroemia, commonly referred to as crape-myrtle, is the primary southern summer-flowering small tree, traditionally associated with the colonial era as was the lilac (Syringa vulgaris L.) in the northern frontiers. Crape-myrtle no longer is just a summer-flowering tree, but is a year-round landscape plant with magnificent trunk bark coloration. ‘Natchez’ and ‘Muskogee’ (4), the first U.S. National Arboretum L. indica × L. fauriei hybrids, have become leading nursery production and landscape plants as much for spectacular trunk bark coloration as the flowers. On the other hand, ‘Tuscarora’ (5) and ‘Tuskegee’ (6), both of similar parentage, lack intense bark coloration but are noteworthy cultivars because of the unique coral to dark pink flowers. More recently, the growth habit diversity was extended by the release of ‘Acoma’, ‘Hopi’, ‘Pecos’, and ‘Zuni’ with semi-dwarf growth habits (7). ‘Biloxi’, ‘Miami’, and ‘Wichita’ bring to 17 the U.S. National Arboretum Lagerstroemia cultivar introductions (2, 3).

Abstract Malus × ‘Adirondack’ is a superior multiple-disease-resistant cultivar with a narrow obovate, upright-branched growth habit. Since there are relatively few crabapples with upright growth habit (i.e., ‘Centurian’, ‘Henningi’, Sentinel’ and ‘Silver Moon’) that have variable disease resistance or tolerance, ‘Adirondack’ is a significant introduction for nursery production. ‘Adirondack’, like ‘Naragansett’ (1), the first U.S. National Arboretum introduction, combines disease resistance and landscape characteristics.

The University of Delaware Botanic Gardens (UDBG) is at a critical juncture in its development. Momentum of shared interest at the University of Delaware and the College of Agriculture and Natural Resources favors the Gardens' advancement as an institution. Having identified endowment planning as a critical and immediate need for UDBG, the goal of this research was to gather pertinent institutional knowledge from select university-based public gardens throughout the United States that had already created an endowment. Key staff were interviewed during the summer of 2005 at Cornell Plantations, JC Raulston Arboretum, Minnesota Landscape Arboretum, and the State Botanic Garden of Georgia. Valuable insights into the procurement and management of endowments within a university-based garden environment were gained through these interviews. Utilizing these results, as well as input from an advisory Task Force, specific recommendations for the University of Delaware Botanic Gardens were made from within the following topic areas: Organizational Structure, Planning, Current Strategies, The Endowment, and The Donor.

An historic feature of the JC Raulston Arboretum (JCRA) is to identify new and unusual ornamental plant materials for landscape use through an active program of observing landscape performance at the JCRA in Raleigh. Introduction of plant materials into commerce occurs primarily through programs conducted in concert with the North Carolina Association of Nurserymen and through a unique policy of “open access” for nurserymen. One program, The JC Raulston Selections Program, returns revenues to the general operations and maintenance functions of the JCRA; others are not revenue generating, and are provided as a service to the industry. To a lesser extent, the general public may participate in receiving new plants via a special program offered through JCRA membership. The JCRA is also an official trial garden site for the All America Selections program and seed companies. Elements of these introduction and evaluation programs will be discussed within the context of the past, present, and plans for the future for program maintenance and possible changes.

The crapemyrtle (Lagerstroemia) is one of the most widely planted and beloved woody ornamental landscape plant in the Southern United States. With hundreds of named cultivars that offer the grower and gardener diverse combinations of flower color, growth habit, and bark characteristics, crapemyrtles are planted primarily for their spectacular bloom in mid to late summer. The crapemyrtle breeding program at the U.S. National Arboretum was started in the early 1960s, and has resulted in the release of 31 improved cultivars of L. indica, L. indica × L. fauriei, and most recently, hybrids between L. indica, L. fauriei, and L. limii. The development of these cultivars, with a focus on the newly released red-flowering cultivars `Arapaho' and `Cheyenne', will be the focus of this poster. Information on Lagerstroemia germplasm, historical perspective, and breeding methodology and goals will be presented.

The Southern Extension and Research Activities/Information Exchange Group-27 (SERA/IEG-27) is sponsored by the Southern Association of Agricultural Experiment Station Directors. Thirteen universities and the U.S. National Arboretum cooperate with official representatives from extension and research programs. The objective of the group is to identify, evaluate, select, and disseminate information on superior, environmentally sustainable, landscape plants for nursery crop production and landscape systems in the southeastern U.S. Plants are distributed to members responding to a request from cooperators for plant evaluation. Those who agree to cooperate are expected to grow the selected liner to landscape size, then transplant it in a landscape setting. The plant is rated for insect, disease, and cold damage, heat stress, growth rate, ornamental flowering and fruiting, fall color, commercial production potential, landscape potential, invasiveness potential, and insect disease transmission potential. Growth rate is evaluated annually by recording plant height and width. Initial bloom date is reported followed by bloom duration in days. Following evaluation, the group collectively and individually disseminates information gained from the plant evaluation system to a wide variety of audiences.

COVID-19 has doubled the prevalence of mental health problems among young adults. In Indonesia, it extends the vulnerability of families, increases economic uncertainty, interrupts food security, and affects psychological well-being. Accordingly, this research examined the correlation between psychological effects and preferred landscape elements. Experiments were conducted in a campus park, arboretum, and a road. Participants captured attractive views during the walk using the Visitor-Employed Photography method and evaluated psychological effects using the Profile of Mood States (POMS) and the State-Trait Anxiety Inventory (STAI) pre-and post-walking. Google Cloud Vision API was used to get the image annotation keywords. The results indicated a correlation between psychological effects and preferred landscape elements. Park therapy components, including plant, flower, and sky, were negatively correlated with negative moods and anxiety levels. These findings presented scientific evidence for the psychological relaxation outcome of walking and prominent components of park therapy to support therapeutic campus greenspace planning.

Abstract. The article explores the issues of the emergence and development of historical parks in Ukraine. There are four periods of formation and development of historical parks in Ukraine: the first ‒ from the times of Kievan Rus to the middle of the 17th century (the origin of park building), the second ‒ from the middle of the 17th century before the revolution of 1917 (construction of mainly private palaces and park ensembles), the third ‒ from 1918 to 1991 (soviet period), the fourth ‒ from 1991 to the present (the period of independence of Ukraine). The definition of the concept «historical park» is given. The park is a work of art. A unique situation in human practice: to create a living and perfect work of art at the same time. Gardens and parks provide this opportunity. The park is history. The historical park preserves and broadcasts this history to us ‒ it is an object of cultural heritage, our common heritage. Sometimes the park is also a museum-reserve and bears the function of preserving heritage. Historical gardens and parks often acquire the status of monuments. Monuments of landscape gardening art are historical and cultural monuments that organically include plants, landscape features (hills, water sources and waterfalls, stream or river valleys, stones, rocks, distant landscape perspectives, sometimes wetlands), architectural structures, sculptures, flower beds, etc. Historical parks of cities include palaces and manor complexes, botanical gardens, city parks and memorial parks, as well as parks-monuments. In total, there are 88 historical parks-monuments of landscape gardening art of national and 426 local significances in Ukraine. Parks-monuments of landscape gardening art of local importance include: parks of culture and recreation, arboretums, woodlands used as recreation parks, and other objects. In particular, in the Odessa region there are 22 parks-monuments, in the city of Odessa ‒ 5 parks-monuments of gardening art (T. Shevchenko Park, Dyukovsky Garden, City Garden, Victory Arboretum, Park named after Savitsky). The article highlights the main problems in the restoration work of historical parks and solutions. The history of the emergence and development of parks in Ukraine is analyzed. It was concluded that the historical parks are multifaceted and interesting not only for architectural ensembles, but also for their biocenosis.

The U.S. National Arboretum has released over 650 new plant cultivars since it was established in 1927. A key to the success of the plant breeding program has been the voluntary participation of universities and private nurseries in evaluating and propagating new plant material. The cooperative evaluation and stock increase programs play a critical role in the successful testing, introduction, and distribution of new cultivars of landscape trees and shrubs. These integrated cooperative programs depend on the involvement of nurserymen, researchers, botanic gardens, or individuals to evaluate potential new cultivars under diverse climatic conditions and hardiness zones, and wholesale propagation nurseries to increase stock of those cultivars destined for release.

INTRODUCTION Universities across the globe are recognizing the need to implement sustainable landscaping practices in order to support wildlife, improve water quality and positively impact human health and wellbeing. Georgia Institute of Technology learned that such sustainable practices, when properly aligned with overarching campus goals, can also enable continuous, collaborative decision-making and student engagement. The Georgia Institute of Technology (Georgia Tech) is a leading research university situated on 426 acres of land in midtown Atlanta, Georgia, with a student population of 27,000 (Fall 2017). An urban oasis in the center of town, Georgia Tech's campus offers 312.5 landscaped acres, 3.5 naturalized acres and 110 acres of buildings. The campus is also a level II certified arboretum boasting 12,000+ trees in its urban forest. Prior to the 1990s, Georgia Tech was commonly referred to as a concrete and brick campus with very little landscape. However, in 1999 all that changed when the Georgia Tech administration decided to invest in sustainable landscaping, including the recruitment of qualified staff with specific skill sets to take on this challenge. The Institute's initial landscape master plan objectives were to reduce impervious surfaces such as surface parking lots, increase woodland coverage and enlarge the tree canopy. A significant amount of sustainable landscape practices and collaborative methods grew from these initial objectives. Establishing a plan with clear goals, having the support of executive leadership and employing the right team members enabled the Georgia Tech campus to be transformed from a concrete jungle to a forested, urban oasis in less than 20 years.

The tree architecture model is a morphological description at a time which is the result of a series of real growths that can be observed at any time. Euphorbiaceae is a group of plants that are often referred to as sap-gums which have characteristics such as their stems containing white sap, finger leaf bones and generally having boxy fruit. One of the functions obtained from the analysis of the tree architecture model is knowing the locations of the generative organs that serve as considerations for carrying out the reproduction process of a tree. The concept of this tree architecture model has been applied to the fields of landscape architecture (aesthetics), urban forest development (protective plants), and soil and water conservation. The purpose of this study was to identify the architectural model of the Euphorbiaceae family tree with the benefit of the research, namely to obtain the results of a report on the architectural model of the Euphorbiaceae family tree, to provide additional information and data for the Arboretum Sylva Indonesia PC.

Full textAbstract:
Prairie dropseed [Sporobolus heterolepis (A. Gray) A. Gray] is a critical North American native grass that is often not incorporated into prairie restoration seed mixes due to its low survival and growth rates. This project investigated using hydrogels, landscape plugs, and native field soil to improve the survival and growth of prairie dropseed. At three tallgrass prairie restoration sites at the Minnesota Landscape Arboretum, we planted prairie dropseed plugs in Fall 2019, Spring 2020, and Fall 2020. When grown in the field from 42 to 94 weeks, we found that potting mix–grown plugs had increased growth as measured by dry weight compared with plugs grown in native soils. Soil medium did not influence survival rates. The use of hydrogels did not demonstrate increased survival or growth compared with plugs planted with water. We recommend land managers and restorationists use plugs grown in commercial potting mix rather than grown in native soils, and we found no advantage in using hydrogels over watering at planting.

Full textAbstract:
Flowering cherries belong to the genus Prunus, consisting primarily of species native to Asia. Despite the popularity of ornamental cherry trees in the landscape, most ornamental Prunus planted in the United States are derived from a limited genetic base of Japanese flowering cherry taxa. Controlled crosses among flowering cherry species carried out over the past 30 years at the U.S. National Arboretum have resulted in the creation of interspecific hybrids among many of these diverse taxa. We used simple sequence repeat (SSR) markers to verify 73 of 84 putative hybrids created from 43 crosses representing 20 parental taxa. All verified hybrids were within the same section (Cerasus or Laurocerasus in the subgenus Cerasus) with no verified hybrids between sections.
