Trachelospermum asiaticum ( Asiatic Jasmine )
A very beautiful, evergreen groundcover, reaching up to 1 foot in height, that may also become a vine, reaching up to 33 ( rarely over 20 ) feet high if provided a lattice. When used as groundcover, the stems root as they touch the ground. The Asiatic Jasmine is native from India through southern China and Korea to Japan; south to Thailand.
The elliptical leaves, up to 4 x 3 ( rarely over 3 ) inches in length, are glossy deep green.
The fragrant, creamy-white flowers, up to 0.7 inches wide, appear late spring into early summer.
Hardy zones 7 to 9 in full sun or shade on well drained soil. It is drought tolerant and moderately drought tolerant. In sun, the foliage may scorch then fall during hard winter freezes; do not declare the plant dead as regrowth is often rapid during late spring into summer.
