Caesar! I have been trying to do my own research on differentiating and sourcing Dioscoreas (particularly edible bulbiferas) ever since I read Toensmeiers book. Your info here is quite a goldmine. You said you have shipped to Arizona before. Have you gotten any feedback on how well they have done? I recently acquired a few ‘Hawaii’ bulbils that I was nervous I lost until they finally came up about a week ago. Arizona gets so hot in the summers that I am planning on providing them some afternoon shade. I know that I would be on a waiting list, but would love to test your CV types. Let me know when you have some available and when shipping gets back to nearly normal. I’ll see if I can come up with something to share.
