The Snail Vine (Vigna Caracalla) is a beautiful vine and well worth growing. It is not very hardy. It generally dies back in winter, doesn't really do well below 50 or 40 degrees. Being a fast grower, it catches up the following spring, growing fast when the weather turns warm and twining up everywhere.
The genus is named after Dominico Vigna an Italian botanist of the 17th century. The species is named after the city of Caracas in Venezuela.

Blooming Habits:
Flowers are usually pale purple, possibly with cream or yellow markings. Their shape reminds of a snail.
