About

Garrya congdonii, the chaparral silktassel or Congdon silktassel, a fairly common evergreen shrub native to the northern California Coast Ranges, is one of a small biological family of approximately twenty known species in the family Garryaceae, most of which are Garrya. While the female and male sexual organs of Congdon silktassel are on separate plants, the pendant male catkins are much more showy. This plant is reasonably attractive and neat enough in its growing habit to be appealing as a landscape species. It is stocked commonly at commercial plant nurseries. All Garrya are associated with warm temperate regions of North America.

Where it grows

Congdon silktassel is found in several plant communities, principally in drier inner California Coast Ranges no more than 20 miles from the Pacific Ocean; the main associations are Coastal chaparral, mixed evergreen forest (near a chaparral area) and northern coastal sage scrub. This plant can tolerate moderately heavy clay soils and serpentine areas, but likes soils pH to lie in the range of six to eight. An example of serpentine soils habitat is in The Cedars of Sonoma County, California.
