Amelanchier, also known as shadbush, serviceberry, sarvisberry, juneberry, Saskatoon, shadblow, shadwood, sugarplum, and wild-plum, is a genus of about 20 species of shrubs and small deciduous trees in the Rosaceae (Rose family). The genus is native to temperate regions of the Northern Hemisphere, growing primarily in early successional habitats. It is most diverse taxonomically in North America, especially in the northern United States and southern Canada, and is native to every state of the United States except Hawaii. Two species also occur in Asia, and one in Europe. These plants are valued horticulturally, and their fruits are important to wildlife. The systematics (taxonomy) of shadbushes has long perplexed botanists, horticulturalists, and others, as suggested by the range in number of species recognized in the genus from 6 to 33 in two recent publications. A major source of complexity comes from the occurrence of apomixis (asexual seed production), polyploidy, and hybridization.
