The Arnold Arboretum of Harvard University, established in 1872, is the oldest public arboretum in North America. This botanical research institution and free public park is located in the Jamaica Plain and Roslindale neighborhoods of Boston, Massachusetts. The landscape was designed by Charles Sprague Sargent and Frederick Law Olmsted and is the second largest "link" in the Emerald Necklace. The Arnold Arboretum's collection of temperate trees, shrubs, and vines has a particular emphasis on the plants of the eastern United States and eastern Asia, where Arboretum staff and colleagues are actively sourcing new material on plant collecting expeditions. The Arboretum supports research in its landscape and in its Weld Hill Research Building.
The H. H. Hunnewell estate in Wellesley, Massachusetts was the country home of H. H. Hunnewell (1810–1902), containing over 500 species of woody plants in 53 families. The estate remains in the family, and includes the first (1854) topiary garden in the United States, featuring intricate geometrically clipped native Eastern white pine and Eastern arborvitae. A collection of specialty greenhouses feature over 1,000 plant species. The estate has been cared for by six generations of the Hunnewell family.

Ulmus laevisPall., variously known as the European white elm, fluttering elm, spreading elm, stately elm and, in the United States, the Russian elm, is a large deciduous tree native to Europe, from France northeast to southern Finland, east beyond the Urals into Kyrgyzstan and Kazakhstan, and southeast to Bulgaria and the Crimea; there are also disjunct populations in the Caucasus and Spain, the latter now considered a relict population rather than an introduction by man, and possibly the origin of the European population. U. laevis is rare in the UK, however its random distribution, together with the absence of any record of its introduction, has led at least one British authority to consider it native. NB: The epithet 'white' elm commonly used by British foresters alluded to the timber of the wych elm.
Bailey Arboretum is a 42-acre (17 ha) arboretum located in Lattingtown, New York, a small village on the North Shore of Long Island.

The Guelph Arboretum of the University of Guelph is an arboretum modeled after the Arnold Arboretum of Harvard University, which was founded in 1872. The Arnold Arboretum is privately endowed as a department of Harvard just as the Guelph Arboretum is a department of the University of Guelph. The University of Guelph Arboretum was founded in the early 1970s and plantings started in 1971 which have developed into specialized gardens, botanical collections, and gene conservation programs. These Arboretums are demonstrations of American gardening which did not come into its own until the late 19th century. With Industrialization, cities grew in size with a need for natural areas, which were included through the creation of public parks. Views of botanical gardens began to change as they became sources for new material of potential horticultural use rather than only public spaces. Today these spaces act in the propagation of plants that have the potential as attractive and functional ornamentals.
The Gothenburg Botanical Garden is located in Gothenburg, Sweden, and is one of the larger botanical gardens in Europe.
Ulmus castaneifoliaHemsley, the chestnut-leafed elm or multinerved elm, is a small deciduous tree found across much of China in broadleaved forests at elevations of 500–1,600 metres (1,600–5,200 ft).
Ulmus uyematsuiHayata, commonly known as the Alishan elm, is endemic to forests at elevations of 800–2,500 metres (2,600–8,200 ft) in Alishan, Chiayi County, central Taiwan, where it is considered one of the minor tree species. The tree was first named and described by the Japanese botanist Bunzō Hayata in 1913, in the aftermath of the First Sino-Japanese War, when Formosa was ceded to Japan.
Ulmus lamellosa, commonly called the Hebei elm, is a small deciduous tree native to four Chinese provinces, Hebei, Henan, Nei Mongol, and Shanxi, to the west and south of Beijing.
Ulmus chenmouiW. C. Cheng, commonly known as the Chenmou, or Langya Mountain elm, is a small deciduous tree from the more temperate provinces of Anhui and Jiangsu in eastern China, where it is found at elevations below 200 m on the Langya Shan and Baohua Shan mountains. The tree was unknown in the West until 1979, when seeds were sent from Beijing to the De Dorschkamp research institute at Wageningen in the Netherlands.

This lush 300-acre (1.2 km2) “urban garden” of native and exotic flora serves as a laboratory for the study, conservation and enrichment of plants, trees, flowers, grasses and many other plants.

The Volčji Potok Arboretum was opened to the public in 1952. It originally formed part of the Souvan family estate in 1885, which was taken over by the University of Ljubljana in 1952 and legally declared a place of cultural and natural heritage of national importance. Now independent of the university, it is the most visited botanical garden in Slovenia and in recent years has become well known for its spring flower shows. The arboretum is primarily a botanical garden for woody plants, the only one in Slovenia.
The elm cultivar UlmusDensa was described from specimens growing near Ashkabad as U. densaLitv. in Schedae ad Herbarium Florae Rossicae (1908). Litvinov, reporting it growing wild in the mountains of Turkestan, Ferghana, and Aksu, as well as in cultivation, considered it a species, a view upheld by the Soviet publications Trees and Shrubs in the USSR (1951) and Flora of Armenia (1962), and by some current plant lists. Other authorities take it to be a form of U minor, distinctive only in its dense crown and upright branching. The Moscow State University herbarium gives (2020) Ulmus minor as the "accepted name" of U. densaLitv..
The U.S. Virgin islands dry forest is a sub-tropical dry forest spanning the United States Virgin Islands with varying degrees of coverage on each island. A dry forest is a habitat type defined by the World Wide Fund for Nature as being a predominantly deciduous forest located in a climate that is warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons which last several months. Dry forests can receive 850-1100mm of precipitation per year. In the case of the U.S. Virgin islands forest high quantities of sea salt from the ocean decreases the growth height of the trees, aiding in the creation of two canopy layers that are commonly found at an elevation below 300 meters. Additionally the unique wind pattern that the islands create may have added to this effect.
