Wavyleaf Silktassel

Wavyleaf silktassel (Garrya elliptica, Garryaceae) is a native broadleaf evergreen shrub from the Coast Range of southwestern Oregon to southern California, reaching about 8 feet tall and 13 feet wide with an erect, dense form. The species is dioecious; male plants produce spectacular dangling yellowish-green catkins 8 to 20 centimeters long in winter, while female catkins are shorter (5 to 9 centimeters). Wavy-margined dark green leaves are the source of the common name.

Wavyleaf silktassel grows in full sun to part shade on moist, well-drained, acidic soil (pH 4.5 to 6.0), hardy in Zones 8a to 8b. The cultivar 'James Roof' produces catkins up to 30 centimeters long and has received the RHS Award of Garden Merit. Male plants are preferred for ornamental use due to longer catkins.
