Best serviceberry cultivars
*Amelanchier* -- serviceberry, shadblow, juneberry, or saskatoon depending on region and species -- is one of the most ecologically valuable genera of woody plants native to North America. Per Missouri Botanical Garden, the genus contains 20--25 species of shrubs and small trees, nearly all North.
Amelanchier — serviceberry, shadblow, juneberry, or saskatoon depending on region and species — is one of the most ecologically valuable genera of woody plants native to North America. Per Missouri Botanical Garden, the genus contains 20—25 species of shrubs and small trees, nearly all North American natives, that provide white flowers in early spring (before most other trees), followed by small blue-purple berries in June, then orange-to-red fall color.
Per Xerces Society research, Amelanchier species host 124 species of Lepidoptera (caterpillars) and are visited by hundreds of native bee species for pollen and nectar. The fruit is consumed by at least 35 bird species.
Species overview
Amelanchier canadensis (Shadblow serviceberry)
Native to eastern North America from Newfoundland to Georgia; zones 3—7. Per Missouri Botanical Garden, it grows 6—20 ft in a multi-stemmed, suckering habit, tolerates wet soils, and blooms in April (coinciding with the migration of shad fish, hence "shadblow"). No widely grown named cultivars; usually sold as straight species.
Amelanchier laevis (Allegheny serviceberry)
Native to eastern North America; zones 4—8; grows 15—25 ft as a single-trunk small tree or large shrub. Per NC State Extension, it has the most distinctive bronze-red new foliage at bloom time, which contrasts with the white flowers. Fruit is sweet and abundant. Less suckering than A. canadensis.
Amelanchier arborea (Downy serviceberry)
The largest of the eastern serviceberries, reaching 15—25 ft, occasionally 40 ft; zones 4—9. Per Missouri Botanical Garden, it grows on dry, rocky hillsides and is the most drought-tolerant eastern species. Fruit is less sweet than A. laevis.
Amelanchier × grandiflora (Apple serviceberry)
A natural hybrid of A. arborea × A. laevis, the most widely planted serviceberry in the nursery trade. Per Cornell Cooperative Extension, it combines the upright-to-arching habit of A. arborea with the superior fruit quality of A. laevis. Most named cultivars in the trade are selections of this hybrid; zones 4—9.
Amelanchier alnifolia (Saskatoon serviceberry)
Native to western North America from Alaska to the northern plains; zones 2—6. Per Oregon State University Extension, saskatoon produces the largest fruit of any serviceberry (up to 3/4 inch diameter), and has been developed into a commercial fruit crop in western Canada. Not well-suited to humid eastern climates (more susceptible to fire blight and rust diseases than eastern species).
