Seeds from this very unusual and rare half hardy perennial vine Phaseolus Caracalla. In no time at all this relative of the Lima bean produces leaves in sets of three and huge lavender curly Qs that will cover a vertical surface up to 15 feet. This plant needs a trellis or other climbing structure to grow on. As the summer gets warmer, this vine seems to thrive and produce more flowers. The blossom is the shape of a contorted corkscrew or a nautilus shell. There is a light hyacinth fragrance and should be plants in full sun for maximum flower production. This vine does self seed sparsely but in very easy to transplant somewhere else or give to friends.
