Ask a neighbor for a few seeds if they have them. Coral vine is a native with light or dark pink or white flowers which is a heavy bloomer throughout the summer. Both Heidi and Mark really like akebia as an outstanding vine. It has attractive evergreen foliage and is not overly aggressive. This is one that maybe difficult to find but well worth the effort.
Coral honeysuckle is normally evergreen and blooms throughout the summer.
It is not as aggressive as the common honeysuckle you see along the side of the roads. Mexican flame vine has orange daisy-like flowers all summer and glossy foliage. One of my favorites is passion vine. They have purple or red flowers which are breathtaking. They die back in the winter but come from the roots in the spring.
