20171202 OIKOS Tree Crops order 4 tubers to fight stilt grass
Grown From Seed -Fertile Flowers - Edible Peas
Virginia is a mix of diploid selections which then produces edible seeds as well as tubers when pollinated by another fertile diploid. We include at least 2 types in each packet of tubers. We were fortunate to grow this strain from seed that are known to be diploids which produce the pea pods and tasty peas along with good tuber production. Most of them come from Afton, Virginia. Each plant is genetically different with different types of tubers from small to medium size. We have made some selections with this seed strain and have found the tubers are in often in dense clusters along the root, making harvesting easier. Tubers are 1- 2 inches in size and have a smooth thin skin. Keep in mind the tubers on Virginia are much smaller than the other selections we have, yet are very fruitful and high yielding. It is possible some selections will be produced much like potatoes in more dense clusters making harvesting much easier. That was our goal when we started growing the seedlings. Available starting in fall of 2017.

The flowers are edible raw or cooked and the seeds are edible cooked, shelled first. Some writers say the tubers are edible raw but that only tells me they never tried to eat one raw, or coped with the gas that produces. Groundnuts have a bitter latex in them and should be cooked first…. . I enjoying slicing up boiled A. americana and frying them — http://www.eattheweeds.com/groundnuts-anti-cancer-treat/

Tubers are planted intact. The buds that give rise to the shoots and rhizomes occur at the distal end of the tubers. The potential of dividing tubers into sections prior to planting needs evaluation. Generally the larger the tuber, the more rapid the early growth

Seeds may be harvested from the time the pods first begin to dry. If left on the vine too long some pods will shatter Tubers are harvested after frost. Since most of the plants are different (originating from seeds), the tubers are harvested with a shovel to insure that genotypes can be evaluated individually. Fortunately, tubers can remain in the soil for extended periods without rotting even under water-logged conditions, thus allowing an extended harvest period.— From "Purdue’s new crop proceedings of 1990" per
