I saw a buddy the other day and he told me you can purchase Dioscoria at the Grocery stores and asain markets in Seattle. Now many Dioscoria are commonly known as Yams, but the list is bewildering, sweet potato, Japanese yam, diakon root, and several I could not pronounce. And also the ends were trimmed off, with no green or root tip.
Has anybody worked with bulbs from the store and gotten them to grow?
I think some of them have "eyes" like potatoes and will shoot up a stem if put into water and get roots from the bottom. You can then take cuttings from those.. I saw one person do that with a batata sweet potato and both the blackie and the chartruce colored one, and kept the potatoes in water/container going for a couple of years, that is how she got her starts each year.
Just to let you guys know that I have NOT tried it yet. lol, but, when I read this it sparked my memory about what I had read here on DG somewhere. I am thinking that eventually maybe they will form a caudex, I did have one that did that but can't remember the name of it, it was some kind of Ivy leaf fat plant.
