Grows well in poor soil, likes full sun. Typically 5-6 foot vines with somewhat sparse leaves. Very attractive to bees and other pollinators.

Prolific producers of seed pods that look like small versions of their domestic pole-bean cousins. Competes well and can form fairly dense mats if it can't climb, although it does not seem to crowd out other vegetation.

Pretty small pink flowers bloom throughout late summer and fall. Harvest is extended, with pods ripening from mid summer to mid fall, the plant will continue blooming until frost and will have pods in various stages of ripening throughout the harvest period.

Care should be take to pinch off at the stem when harvesting mature pods, as clipping off the top of the pod will cause the p... read more

This plant growing wild reaches 8 to 10 feet and does not have dense foliage. When grown in flower beds with regular feeding and watering, this plant has fairly dense, attractive foliage and grows very rapidly in warm to hot weather. The blooms start when daytime highs reach the mid 80s. Once heavy blooming occurs, the growth slows.
In my flower bed it was growing at a rate of more than 4 feet a day and started blooming in a very short time, less than 3 weeks. The seed pods are like small green beans. They turn brown, then when ready to pick, turn tan.
