Hi Kevin,
I doubt you'll get much of a response on this forum. I looked the plant up, and it seems pretty neat. I'm surprised how few hits came up on google about it. Anyway, the forums I would post on are the Native Plants, Seed Trading, and Winter Sowing forums.
Good Luck,
Remy

Thanks Remy, I'll do that.
I used to grow this plant recently, found the seeds two years ago, but now it seems to have disappeared off the face of the earth.
