Funny thing about lisianthus seeds. I had a plant with blooms expire in my GH a couple of years ago and it sort of just sat there over the summer (in that super heated GH; I close it up in the summer and let it get really hot to sort of disinfect everything--hot enough to melt a plastic clock I'd left in there!) and the following winter. The next spring, I was cleaning up and saw what looked like seeds. So I sprinkled them over some potting soil, and lo! I got several plants from those poor neglected seeds!
