This beautiful semi-evergreen vine produces small, yellow, double spring flowers that bloom for weeks, scenting your garden with a sweet aroma. Train the thornless stems of this climbing vine along a fence, arbor, lattice, or other structure. It loves to climb and then hang down when it reaches the top of its destination.  It can grow as high as 20 feet and makes an impressive show cascading from a tree.  You can even create a living sculpture, training it to grow in a design against a flat wall. This fascinating plant is excellent for desert gardens because of its tolerance to drought.
