I have raised Psoralea pinnata from seed. No special requirement needed except to nick the seet coat at time of sowing. Maybe Ps. onobrychis is similar in that respect, but I have not tried that species. Is the seed hard? Andrew San Diego From: pbs-bounces@lists.ibiblio.org [mailto:pbs-bounces@lists.ibiblio.org] On Behalf Of Dennis Kramb I suppose this species is borderline geophytic. It's rhizomatous, anyway. So here goes... I've tried, and failed, to establish this wildflower in my prairie garden. All my attempts were with using nursery propagated seedlings of local populations (from prairie remnants in Dayton Ohio). I'm trying again by seed, from a new source. Does anyone know of any special requirements for success? I'm also going to try Zigadenus elegans from seed. Thanks! Dennis in Cincinnati
