| Amelanchier
utahensis Koehne
by Helen Fairly,
Native Plants Class 2002
Common names: Serviceberry; also Hairy Serviceberry, Shadberry, Shadbush
or Juneberry.
Family: Rosacae.
Synonymy: None.
Etymology: The epithet utahensis refers to its type locality In
Utah.
Identification
Growth form: Serviceberry is a tall shrub or small tree, 6 to 15 feet
tall, with intricately branched and generally upward pointing growth pattern.
Roots: The root system consists of
Stem: Stems have smooth gray bark.
Leaves: Leaves are alternate, simple, deciduous, round to oval
(2-4 cm long, 1.7-2.5 cm wide), and slightly hairy. Lower leaf margins
are smooth, but upper margins are toothed.
Inflorescence/flowers: Inflorescences are tiny white, star-shaped,
delightfully fragrant flowers with five slender petals often growing in
clusters of 3 to 6. The flowers appear in spring before the plant leafs
out.
Fruit: The fruit is small, fleshy, vaguely apple-like in form,
pale orange to yellow in color and slightly sweet.
Similar species: Amelanchier alnifolia (Western
Serviceberry) is a close relative of Utah Serrviceberry. The two species
can be difficult to distinguish, and they often hybridize (4). Amelanchier
alnifolia can be distinguished from A. uthahensis by having
smoother leaves and a more tree-like growth habit, plus the fruits are
usually dark reddish-purple in color..
Ecology
Life history: Serviceberry is a long-lived perennial shrub.
Native/introduced: Native.
Photosynthetic pathway: C3
Phenology: In northern Arizona, Serviceberry flowers from late
March to May. Fruits are disseminated in June, July and August (1).
Distribution: Alaska and Yukon, east to Minnesota, south to Arizona,
and from northern California and east to the Rocky Mountains. It is usually
found growing on rocky, moist (north facing) slopes in the pinyon-juniper
woodlands and ponderosa pine forests. In Arizona, Serviceberry is usually
found between 1200-2500 m (4000-8000 feet) elevation, although it is reported
to occur as low as 600 m (2000 feet) and as high as 3050 m (10,000 ft)
(1,2) .
Uses
Wildlife: Serviceberry is an important food for over 60 species of
birds and mammal (1). The berries are eaten by birds, small rodents, and
coyotes and foliage is extensively browsed by deer and elk. The berries
were widely used by Native Americans. They were eaten fresh or dried,
crushed and caked, and stored for winter use. Shoots were used for basketmaking
by the Havasupai and Apache (1, 5). EuroAmerican pioneers used the fruits
in wines, jams and jellies.
