I wintersowed once and was unsuccessful. Perhaps it's my zone. I grow them in baggies inside, transplant into pots, then grow in pots for a year before transferring outside into garden soil. I summer all the pots outside on my deck.
I have been attempting different methods to see what results and how fast. If you know anything about my patience, well, uh, I lack it, so the faster they grow up, the better.
Let us keep up with your progress Neal. We have a nice lily from seed area here for you to show off too.
