Coast Silktassel
Garrya elliptica
  
46 Nurseries Carry This Plant

About Coast Silktassel (Garrya elliptica) 46 Nurseries Carry This Plant Coast Silktassel (Garrya elliptica) is a common evergreen shrub native to the coastal ranges of southern Oregon and California, south to Los Angeles County. It is one of a small biological family of approximately 20 known species in the family Garryaceae, most of which are Garrya. Female and male sexual organs of all the Garrya are found on separate plants. All Garrya are associated with warm temperate regions of North America.

This native plant's attractiveness and neat growing habit make it appealing as a landscape species. Many commercial plant nurseries stock it, and it is a widely used Garrya for landscape purposes.

Coast Silktassel has a multi-branching structure yielding an almost spherical form. All plants in the genus Garrya have opposite leaves with a tough leathery feel, glossy green on top. The dioecious flowers are concentrated in flower clusters which cascade downward as catkins. Though the Coast Silktassel manifests separate male and female plants, the pendant male catkins are much more showy and are grey-green and up to almost 12 inches long; female catkins are shorter and silver-grey. Although the flowers bloom in January and February, dried leaves remain on the tree well into summer as light gray decorations.

The plant has smooth, dark bark, dark-greenish when young, but with age the bark roughens. New twigs are green and moderately stout.

'James Roof' is one popular horticultural variety known for its especially long tassels. To learn more, visit the Jepson Herbarium's YouTube channel and watch a short video about this species:
