The striking purple color of Amethyst draws attention at farm stands and farmers' markets. Amethyst is a purple podded specialty bean that is produced on a vigorous bush plant. The round pods are 5 to 5-1/2" long completely stringless, and if the plants are kept picked, they produce continuously over a long period. The attractive and straight pods also have a uniform color. Pods lose their color when cooked in hot water.
