- Description
-
Silky Dogwood is a deciduous tree that may grow 10 to 15 feet tall. The leaves are alternate and acutely veined with a smooth margin. The bark is smooth and red-purple in young trees. As the tree ages, the bark turns brown and develops shallow fissures. In late spring, small, white flowers mature in clusters. The small tree produces berries that develop in flat-topped clusters.
Tolerates close to full shade. Benefits from a 2-4” mulch which will help keep roots cool and moist in summer. Branches that touch the ground may root at the nodes. When left alone, this shrub may spread to form thickets.
Good shrub for moist to wet areas of the landscape. Not overly ornamental. Somewhat wild and unkempt for placement in prominent areas. Good selection for moist woodlands, naturalized areas, along steams/ponds or for erosion control.
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.
