Corkscrew Flower, Shell Vine, Caracalla Vine, Snail Vine

Description

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.Well-established, seed grown plants (ours are seed grown) will develop the tubers necessary to make these plants perennial into zone 9B with protection. Cutting grown plants do not appear to do so, at least in our experience. Corkscrew Vines should have excellent winter drainage to prevent root rot while dormant. An insulating, loose breathable mulch will further help to protect any above ground parts that could be sensitive to to hard frosts and freezes. Plant young plants in spring after the danger of frost has passed to give them a full 9 months of growth and the best chance to survive zone 9B winters and in areas where their hardiness is questionable.There is much confusion in the nursery trade between this plant,Vigna caracalla, and theSnail Vine,Phaseolus gigantea, which produces purple to lavender flowers singly or in small clusters. You can view it on our websitehere. Other synonyms forVigna caracallaincludePhaseolus caracallaandCochliasanthus caracalla. We do know the difference.
