Allegheny Serviceberry

Allegheny Serviceberry - Amelanchier laevis
Rose Family (Rosaceae)


Introduction: Allegheny serviceberry is a multistemmed small tree reaching up to 25 feet tall. It produces large white flowers in spring and bluish green fruit.
Culture: Allegheny serviceberry grows best in partial shade; it will show signs of stress if grown in full sun in dry areas. This tree prefers well-drained, slightly alkaline to acidic loam or sand. Disease and insect problems include fire blight, spider mites and borers, which infest trees under stress from drought. Heavy nitrogen fertilization exacerbates the fire blight problem. Allegheny serviceberry is hardy in Zones 4 to 8, possibly 9.
