Rare colored lima bean nonexistent in cultivation in the US to my knowledge. Perennial vines are long season subtropical vines that will continue many years if conditions are frost free. Vey beautiful jewelry grade beans are edible and delicious, but like all Limas special attention must taken to leach the toxins. *Never eat any part of plant except the seed. And insure you boil them, well pour off water then cook again as you wish.
