Common Problems

The bean mosaic diseases cause plants to turn a yellowish green and produce few or no pods. The leaves on infected plants are a mottled yellow and are usually irregularly shaped. The only satisfactory control for these diseases is to use mosaic-resistant bean varieties.

Bright yellow or brown spots on the leaves or water-soaked spots on the pods are signs of bacterial bean blight. Bacterial blight is best controlled by planting disease-free seed; avoiding contact with wet bean plants; and removing all bean debris from the garden.


Open pollinated means this plants flowers are fertilized by bees, moths, birds, bats, and even the wind or rain. The seed that forms produces the same plant the following year. 

All heirlooms are open pollinated, but not all open pollinated plants are heirlooms. Only a small fraction of the plant world is considered heirloom.

This variety has a history of being passed down within communities and families as early as the 1700's, similar to the generational sharing of items like jewelry or furniture.

Snap beans, string beans, and pole beans are the immature pod and beans of dried legumes. All of these will mature to produce fat seeds and tough inedible pods. The nutritional profile of mature dried beans is very different from that of green beans. Green beans are a good source of carbohydrates. They are a moderate source of protein, dietary fiber, Vitamin C and beta carotene. The beta carotene is converted to vitamin A in the body. Green beans also contain small amounts of calcium and other trace nutrients.
