I had to google it, since I read somewhere that Dioscorea elephantipes/Hottentotten bread is supposed to be edible after specific preparations. Hmm.
It seems Dioscorea discolor is available at certain grocery markets. Fascinating!! Surely other types of plant grown from tubers can be bought like that? https://www.missouribotanicalg...
