Additional comments: Star jasmine is less refined and more coarse textured than T. asiaticum. But ohh!! what flower fragrance. To use as a ground cover,  space one gallon container transplants at about 2 to 3 feet on center for eventual full cover.

Star jasmine weeps a heavy, sticky, and milky-in-appearance latex exudate from any cut stem. Be careful of this when pruning star jasmine. Milky latex is a skin irritant to some.
