DesertAddie, I just asked the same question last week LOL! I guess great minds think alike!

Desert Addie & Trolip.. I did that about 3-4 weeks ago. Collected the pods after they dried from the main plant. Tons of seeds from each pod. Mixed 1 part vermiculite & 1 part Perlite. Punched hole at ottom of 5 oz plastic drinking cups. filled with the mixed mediuim, dropped 4-8 seeds on top, covered with thin layer of medium. seeds were burried about 1/4" top. Placed on window sill (got 3-4 hrs sun daily). They sprouted from 7-10 days and are now about 2 inches tall. They say they should be "hardened" prior to planting oudoors by placing them outdoors for around 2 hrs per day (i don't know how long) prior to planting. At this time I don't know how long I'll wait to plant so still on window sill. Let me know if you do it...
