Amelanchier
Amelanchier (/æməˈlænʃɪər/ am-ə-LAN-sheer), also known as shadbush, shadwood or shadblow, serviceberry or sarvisberry (or just sarvis), juneberry, saskatoon, sugarplum, wild-plum or chuckley pear, is a genus of about 20 species of deciduous-leaved shrubs and small trees in the rose family (Rosaceae).
Amelanchier 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 northeastern United States and adjacent southeastern Canada, and at least one species is native to every U.S. state except Hawaii and to every Canadian province and territory. Four species also occur in Asia, and two in Europe.
A pome fruit, the berries are commonly consumed by wildlife and picked by humans for uses in baked goods. The Canadian city of Saskatoon, Saskatchewan is named after a Cree term for the berry.
The various species of Amelanchier grow to 0.2–20 metres (1⁄2–65+1⁄2 ft) tall; some are small trees, some are multistemmed, clump-forming shrubs, and yet others form extensive low shrubby patches (clones). The bark is gray or less often brown, and in tree species smooth or fissuring when older. The leaves are deciduous, cauline, alternate, simple, lanceolate to elliptic to orbiculate, 0.5–10 by 0.5–5.5 centimetres (1⁄4 in–4 in × 1⁄4 in–2+1⁄4 in), thin to coriaceous, with surfaces above glabrous or densely tomentose at flowering, and glabrous or more or less hairy beneath at maturity.[citation needed]
The inflorescences are terminal, with 1–20 flowers, erect or drooping, either in clusters of one to four flowers, or in racemes with 4–20 flowers. The flowers have five white (rarely somewhat pink, yellow, or streaked with red), linear to orbiculate petals, 2.6–25 millimetres (1⁄8–1 in) long, with the petals in one species (A. nantucketensis) often andropetalous (bearing apical microsporangia adaxially). The flowers appear in early spring, "when the shad run" according to North-American tradition (leading to names such as "shadbush"). The fruit is a berrylike pome, red to purple to nearly black at maturity, 5–15 mm (1⁄4–5⁄8 in) in diameter, insipid to delectably sweet, maturing in summer.
Amelanchier plants are valued horticulturally, and their fruits are important to wildlife. Some orchards are cultivated in the Canadian Prairie provinces, which are subjected to severe winter cold of −60 °C (−76 °F), indicating the hardiness of the plant having a lifespan up to 50 years.
The taxonomic classification 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 hybridization, polyploidy, and apomixis (asexual seed production), making species difficult to characterize and identify.
