The true demand  is for the VIGNA  Caracalla, a favorite of Thomas Jefferson's, the Corskscrew Vine, Snail Vine, or Caracalla Bean produces large clusters of fragrant white and lavender coiling buds and flowers that fade to a creamy yellow just before dropping. The Corkscrew Vine is a vigorous climber that grows from a tuberous, somewhat potato-like, root that it can return from in mild winter climates. The intricate late summer and fall blooming flowers attract a variety of pollinators, particularly larger bees. Item# 373.

There exists a "Corkscrew vine, a.k.a. Snail vine" that looks very similar to the V. caracallas vine, but has no fragrance, and can become a pest.  It is more hardy  of the two.   We do not grow it.
