Greetings, I collected seeds of Hesperocallis undulata in Anza-Borrego Desert State Park in March of 2009. The seeds are flat and matte-black and do not appear it first to be particularly durable. I was unable to plant these seeds in fall of 2009 and was doubtful they would be viable after a year and a half in storage (which consisted of a dish in a drawer in my unheated greenhouse). I decided to give them a try this year and planted them during a seed-sowing stint earlier this fall. I checked the pot today and the seeds are sprouting very well - greater than 50% at this point. Apparently the seeds are tougher than they appear! If anyone missed-out on the recent offering of these seeds I have some I can share. Please email me privately if so. -|<ipp
