Asian jasmine grows very rapidly and tends to become quite dense. It reaches a height of around 6 to 12 inches and each plant spreads out to about 3 feet in all directions. The plant sends out runners, much like certain members of the grass family such as spider plants and quack grass. It is a plant that does not require a lot of maintenance after the first year. During that time, however, the jasmine is still vulnerable and weak.
Most Asian jasmine plants have deep green, shiny, oval-shaped leaves. This plant is evergreen and will retain its color and freshness throughout even the cold winter months, providing they remain relatively mild. If the weather is more severe than usual, however, it may drop its leaves temporarily, turn brown or even die. This plant tolerates shade and direct sun equally well and spreads quickly to cover a large territory. It is, in fact, likely to take over the garden area if allowed to stretch out.
This plant needs plenty of moisture to get started for the first year. If it is allowed to dry out during that time, it may not survive. After that it is drought resistant to some degree. It starts well in shady areas but is not afraid to spread to full sun areas as time goes by. This plant can be placed near a trellis and trained to climb it as it sends out runners much like grass does.
True Asian jasmine does not flower, so if the plant in question is flowering, it is another type of jasmine, such as Confederate or yellow star Jasmine and not the same plant at all. True Asian jasmine comes with plain dark green leaves, variegated leaves (green with stripes) and also grows in dwarf form. Asian jasmine is also called Japanese star jasmine and Asiatic jasmine and is native to Japan and Korea.
