Anyone tried growing Triteleia?

I've been researching native american food sources lately, and I keep finding references about eating Triteleia laxa and Triteleia grandiflora bulbs. Has anyone tried growing these? It might be interesting to attempt to breed a variety with larger bulbs as a food crop.

Also if anyone has info about the edibility of other triteleia species and their interbreeding potential, I would love to hear about it.
