Yes, I save seed from the HBV. I, too, am anxious to try the White Hyacinth Bean next year. I'd be happy to send you some of these white seeds. I can't yet vouch for them though since they were given to me. I can also send some of the purple HVB seeds any time a killing frost beats you to the seeds.
'Henry Eilers' is quickly becoming a fave. It preformed so admirably with no problems here in its first year. And it doesn't flop over like some of the other tall ones.
A recent photo. I'm harvesting seed pods as we speak.
