Detailed Map >


About Wavyleaf Silktassel (Garrya elliptica) Garrya elliptica (Coast silk-tassel) is a common evergreen shrub native to the coastal ranges of California and southern Oregon, south to Los Angeles County. It reaches a height of two to five meters. It is one of a small biological family of approximately twenty 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. This is an example of a native plant that is sufficiently attractive and neat of growing habit to be appealing as a landscape species. It is stocked at many commercial plant nurseries, and is clearly a widely used Garrya for landscape purposes. This plant is sometimes known as Silk Tassel Bush or Wavyleaf Silktassel. All Garrya are associated with warm temperate regions of North America. Coast silk-tassel (sometimes called Wavyleaf silk-tassel) has a multi-furcate branching structure yielding an almost spherical form. The height can attain five meters, but more likely averages three meters in the wild. Coast silk-tassel, as all the genus Garrya, have opposite leaves that have a tough leathery feel, glossy green on top, but paler and duller on the underside. The dioecious flowers are concentrated in flower clusters which cascade downward as aments of approximately four to six centimeters in length. While the Coast silk-tassel manifests separate male and female plants, the pendant male catkins are much more showy and are grey-green and up to 30 centimeters long; the female ones 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.
