Garrya elliptica From Wikipedia, the free encyclopedia Garrya elliptica (Coast silktassel, Silk Tassel Bush or Wavyleaf Silktassel) is a common evergreen shrub native to the coastal ranges of California and southern Oregon, that 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. All Garrya are associated with warm temperate regions of North America. Female and male sexual organs of all the Garrya are found on separate plants.

The height can attain five meters15 feet, but more likely averages three meters10 feet in the wild. Coast silktassel, 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. Flowers [edit] Kingdom: Plantae (unranked): Angiosperms (unranked): Eudicots (unranked): Asterids Order: Garryales Family: Garryaceae Genus: Garrya Species: G. elliptica Binomial name Garrya elliptica The dioecious flowers are concentrated in inflorescences which cascade downward as aments of approximately four to six Dougl. ex Lindl. centimeters in length.[1] While the Coast silktassel manifests separate male and female plants, the pendant male catkins are much more showy and are greygreen and up to 30 centimeters long; the female ones are shorter and silvergrey. Although the flowers bloom in January and February, dried bracts remain on the tree well into summer as light gray decorations. The plant has smooth dark bark, darkgreenish when young, but with age the bark roughens. New twigs are green and moderately stout. For pistillate flowers, above each small bract there is a solitary flower inside the inflorescence. This plant produces tiny dark seeds that can become airborne as small fluffy windblown cotton .The ripened purplish black fruit of about one centimeter in diameter has a hard desiccated coating, but is rather fleshy on the interior. In the case of stamenate infloresences, there are a total of four stamens per flower; moreover, above each bract pair there is a triplet of flowers. The cultivar "James roof" has catkins up to 12 inches in length Leaves [edit] The unique characteristics of Garrya elliptica are its waxy convex leaves with wavy leaf margins, coupled with dense individual hairs on the leaf undersides that are scarcely distinguishable with a hand lens. Its leaf blades are six to eight centimeters in length, and has petioles which range in length from six to twelve millimeters. For identification purposes Congdon silktassel (Garrya congdonii) is most closely related. Congdon silktassel has the same leaf appearance, but leaf hairs are distinguishable with a hand lens and both leaf blades and petioles are about two thirds the size of Coast silktassel. Both Fremont silktassel (Garrya fremontii) and Ashy silktassel (Garrya flavescens) have similar fruit characteristics, but have a flat leaf margin. Distribution and habitat [edit] Garrya elliptica is found in several plant communities, principally in drier coastal California and southern Oregon no more than 20 miles from the Pacific Ocean; the main associations are coastal sage and chaparral ecoregion, Northern coastal scrub, Mixed evergreen coastal forest and Northern coastal sage scrub. [2] This plant can tolerate moderately heavy clay soils and serpentine areas, but likes soils pH to lie in the range of six to eight. This plant is not grazed to a great degree by deer or rabbits, and is hardy to cold temperatures of about 15 degrees Fahrenheit. It is moderately drought tolerant, but is more luxuriant with rainfall of about 25 inches per annum. Coast silktassel is usually found at elevations above 200 meters. This species is usually found within the mountains of the Pacific Coast range, such as Montara Mountain, San Bruno Mountain and the coast range in Napa County. Cultivation [edit] Garrya elliptica is appealing as a ornamental plant with a neat growing habit, and is a widely used Garrya for landscape purposes.[3] Cultivars include: G.elliptica "Evie" G.elliptica "James Roof" References 1. 2. 3.
