Most of us know this, but in case it's news, your beautiful Rancho Gordo heirloom beans are also viable heirloom seeds.
Just toss some in the ground and cover by about half an inch, keep them moist (but not over-saturated) and within a week you'll be the proud parent of a new crop of legumes.
You can eat them as green beans, shelling beans or dried beans. They are hard to screw up. Runner beans seem to prefer cooler nights but beans are easy.
