Cornus amomum

Common Name(s):

Phonetic Spelling
KOR-nus ah-MOH-mum
Description

Silky Dogwood is a large deciduous shrub that is typically found in moist lowland areas, swamp borders, floodplains, shrub wetlands, and along streams and ponds in Eastern North America. Its preference is for part shade in rich moist soils but will tolerate almost full shade. If the stems touch the ground they will root and the plant can form thickets in the wild.

The showy white spring flowers are followed by blue fruits that the birds will happily eat. 

Problems: Susceptible to scale. Other insect pests include borers and leaf miners. Infrequent disease problems include leaf spot, crown canker, blights, root rot and powdery mildew.
