Rattlesnake bean

The rattlesnake bean is an heirloom cultivar of pole bean (Phaseolus vulgaris). The pods are 6 to 8-inches long with purple markings, and the seeds are light brown with brown markings, still visible after cooking. They are named for the snake-like manner in which their pods coil around the vine.^[1]

Rattlesnake beans favor hot weather such as in American Southeast and mid-Atlantic, though they are easy to grow elsewhere as well. They have an average to long time from germination to harvest, ranging from 60 to 90 days.^[2] They should be harvested frequently for increased yields. Plant grows up to ten feet, producing purple flowers before the pods.^[3][4]

As fresh snap beans, they are sweet-tasting.^[2] Cooked dry beans have an intense flavor that combines well with strong spices, making them suitable for chili con carne.^[5]
