Kew Gardens and the Powers that Be notwithstanding, I think Vigna caracalla and Phaseolus caracalla are two entirely different plants. Not only do the flowers differ in color and structure, but also -- and most importantly, to many gardeners -- Phaseolus caracalla has no scent. The fragrance of Vigna caracalla is thick & sweet, like oriental lilies or jasmine.

In my zone 6/7, I probably need to start them in January or keep them in a container... I've started seeds in Feb., and they were barely coming into bloom when the first frost hit in early October. Heat definitely speeds germination, as does scarifying & soaking.

The Corkscrew vine is a fast growing perennial vine, twining and climbing to heights of 15 to 20 feet. Preferring full sun, humidity and temperatures above 50ºF, the vine dies back in the winter. The beautiful and fragrant blooms are produced from summer to fall and have a snail like appearance, giving it another common name of "Snail Vine".

The "Powers that be," GRIN and Kew Gardens, decided that Vigna caracalla, aka Corkscrew Vine, and Vigna phaseolus caracalla were the same species - Vigna caracalla. The flowers and buds are totally different in form.

The Snail Vine is always lavender/purple.

The Corkscrew Vine is white and lavender/purple morphing into amber as the flower ages.

A word about harvesting seeds from V. caracalla, both the Corkscrew and Snail Vines. Once the pod dries and is removed from the plant, split open the pod inside a plastic baggie because the second you split the pod it literally snaps open scattering some of the seeds.
