Saskatoon Serviceberry
Amelanchier alnifolia
  
About Saskatoon Serviceberry (Amelanchier alnifolia) 13 Nurseries Carry This Plant Saskatoon Serviceberry (Amelanchier alnifolia) is beautiful shrub that grows primarily in northern California and the Sierra mountains. It tends to grow in well draining open places and hillsides at elevations from 200-8500 feet. Saskatoon Serviceberry grows in an upright form to a height of 15-35 feet, with active growth during the spring and summer. It usually has a rounded shrubby form, though it can sometimes grow more upright especially in shadier areas. Flowers are white and striking, and bloom in the early summer. Leaves are medium green and deciduous. The serviceberry fruit tastes a lot like blueberries. It is an important food source for birds and animals, was an important food source for northwestern Native Americans and is still grown commercially for human consumption.

Saskatoon Serviceberry is a great choice for native gardens in northern California and throughout the Sierras. Great for attracting birds and other small animals. It's fairly easy to grow as long as it is in a spot with excellent drainage, though it prefers loam or sandy loam. In its natural range, it prefers full sun, needs little or no supplementary irrigation, and is fast growing and long lived - reaching 6 feet in 3-6 years and lasting about 60 years. Outside its natural range, it prefers part shade and regular supplemental irrigation, and is slow growing and short lived.

Maintenance
Maintenance
Serviceberries are prone to a number of diseases, including rusts, fireblight, powdery mildew, and Entomosporium leaf, and insects such as elm aphid, saskatoon, sawfly, mites and leaf rollers. Prune as described above to reduce chances of diseases, and plant insectary crops such as Queen Anne's lace, white clover, cowpea and yarrow nearby to keep insects under control.. Prune to an open form in order to increase light and air flow though the plant, and reduce the chances of disease. For the first three years, only remove low branches and dead, or diseased stems. In order to maximize berry production, start regular pruning after the plant reaches about 6 feet tall (3-6 years), and regularly remove older branches.

Propagation
Propagation?
Easy to propogate, and readily grows nearby seedlings. Seedling will grow about 1 foot per year. For propagating by seed: 4-6 mos. stratification ( USDA Forest Service). 4 mos. warm then 4 mos. cold stratification (Heit 1971) may improve germination.
