Magnolia stellata, sometimes called the star magnolia, is a slow-growing shrub or small tree native to Japan. It bears large, showy white or pink flowers in early spring, before its leaves open. This species is closely related to the Kobushi magnolia, and is treated by many botanists as a variety or even a cultivar of that. However, Magnolia stellata was accepted as a distinct species in the 1998 monograph by Hunt.
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 Cheyenne Botanic Gardens are located in Lions Park in Cheyenne, Wyoming, with an associated High Plains Arboretum located five miles (8 km) northwest of Cheyenne at an elevation of 6,200 feet (1,900 m).

The University of Wisconsin–Madison Arboretum is a teaching and research facility of the University of Wisconsin–Madison and the site of historic research in ecological restoration. In addition to its 1,260 acres (5 km2) in Madison, Wisconsin, the Arboretum also manages 520 acres (210 ha) of remnant forests and prairies throughout Wisconsin. It was designated a National Historic Landmark in 2021, in recognition for its role as a pioneer in the field of ecological restoration.
Division, in horticulture and gardening, is a method of asexual plant propagation, where the plant is broken up into two or more parts. Both the root and crown of each part is kept intact. The technique is of ancient origin, and has long been used to propagate bulbs such as garlic and saffron. Division is mainly practiced by gardeners and very small nurseries, as most commercial plant propagation is now done through plant tissue culture.
Ulmus 'Morton Glossy' is a hybrid cultivar raised by the Morton Arboretum, Illinois. Originally named 'Charisma' until it was realized that name had already been registered for another plant, the tree was derived from a crossing of two other hybrid cultivars grown at the Morton: Accolade and Vanguard. Tested in the US National Elm Trial coordinated by Colorado State University, Triumph averaged a survival rate of 86% after 10 years. Triumph was introduced to the UK in 2006 by the Frank P. Matthews nursery in Worcestershire.
The Field Elm cultivar Ulmus minor 'Virgata' (:'twiggy') was first described, as Ulmus campestris virgata, by Pepin in Revue Horticole (1865) from a stand of some thirty trees beside a monastery at Grand-Puits near Nangis, Seine-et-Marne, said to have been planted by the friars in 1789 and propagated in 1835 by Cochet's nursery at Grisy-Suisnes. Pepin noted that in France 'Virgata' was sometimes confused with another, less vigorous elm cultivated as 'Orme pyramidal'.
Ulmus 'Arno' is an Italian hybrid cultivar derived from a crossing of 'Plantyn' with the Siberian Elm Ulmus pumila clone S.2. It was raised by the Istituto per la Protezione delle Piante (IPP) in Florence, and released in 2007. However, 'Arno' was not a commercial success; propagation had ceased by 2010, and it is no longer patent protected.
Ulmus 'Fiorente' is a hybrid cultivar elm derived from a crossing of the Siberian Elm Ulmus pumila clone 'S.10' from Lucca, Italy, with the Ulmus minor clone 'C.02' from Lungarno, Florence, by the Istituto per la Protezione delle Piante (IPP), part of the Italian National Research Council, in Florence. 'Fiorente' was patented in 2006, and released to commerce in 2012.

Quercus × warei is a hybrid oak tree in the genus Quercus. The tree is a hybrid of Quercus roburL. f. fastigiata(Lam.) O. Schwarz and Quercus bicolorWilld. . The hybrid is named for the American dendrologist George Ware, former Research Director at the Morton Arboretum, Illinois.
The Seed Herbarium Image Project (SHIP), is an initiative of the Arnold Arboretum of Harvard University to create a web-based repository of high-resolution digital images documenting the morphology of woody plant seeds and selected fruit structures. Headquartered at the Arboretum’s Dana Greenhouse facility and coordinated and photographed by curatorial assistant Julie McIntosh Shapiro, the Seed Herbarium Image Project supports the work of educators and professionals in horticulture and the botanical sciences, particularly in conservation research and management of rare and endangered species. The digitized images of seeds offer an important new aid for teaching seed identification—a fundamental skill in plant propagation, hybridization, and distribution—and serve as a resource for nurserymen, horticulturists, botanical curators, taxonomists, ecologists, and the general public. SHIP also provides an online resource for botanical institutions and nurseries to verify their collections and inventories. SHIP is made possible through the generous support of the Stanley Smith Horticultural Trust, Cabot Family Charitable Trust, and the J. Frank Schmidt Family Charitable Foundation.
The James Pass Arboretum was established by the City of Syracuse, New York through the philanthropy of Adelaide Salisbury Pass and family with the guidance and cooperation of the State College of Forestry to be a classic arboretum in the tradition of the Arnold Arboretum in Boston MA, that is, a museum of woody plants designed for education and horticultural display.

Bluebell Arboretum is an arboretum and associated plant nursery near the village of Smisby in South Derbyshire, England. It is a Royal Horticultural Society recommended garden, comprising a large selection of rare trees, shrubs and climbers growing in a woodland garden. Planting was started by the owners, Suzette and Robert Vernon in 1992 on what was then a six acre meadow, just under 500 feet above sea level. The arboretum was officially opened by Roy Lancaster, OBE VMH in 1997, and has since been expanded and is now open to the public throughgout the year, excluding Sundays during the winter months.
Jelena de Belder-Kovačič was a Slovenian-Belgian botanist and horticulturist, who worked extensively on the taxonomy and preservation of plant specimens, gaining an international reputation for her development of the Kalmthout and Hemelrijk Arboreta. Several varieties of plants she cultivated were recognized with awards from the Royal Horticultural Society in London and she was elevated to Baroness by Albert II of Belgium for her contributions to dendrology.
Sidney Waxman (1923–2005) was an American botanist and horticulturist who served as Professor of Ornamental Horticulture at the University of Connecticut's main campus in Storrs for more than thirty years (1957-1991), continuing to work on his ornamentals long after retirement. His research interests included plant photoperiodism, tissue culture, and witches’ brooms. He founded UConn's experimental plant nursery and built a national reputation for cultivation of dwarf conifers from witch's brooms, developing and naming thirty-four distinct cultivars. He also cultivated Japanese umbrella pines, larches, cinnamon bark maple, hemlocks, and azaleas. Waxman raised more than 200,000 seedlings to create a total of forty cultivars. Many of his varieties were sold in plant nurseries and garden centers.
