It's still too early to put any of them in the ground, but I think we can safely call the winter sow experiment a success.
Despite a few wind storms, and the lawn maintenance boys intentionally aiming a leaf blower at them.... everything its doing pretty well.
The clear winner are the Mammoth sunflowers
The only ones that weren't a success were the Chives and the Sweet Peas. Both were a gamble because winter sow method is really meant for perennials. I still have half a package of both left; the Chives will probably be tossed directly in one of the gardens once the threat of frost has passed, and I'll try the Sweet Peas in a pot again (I can get them grow, just not bloom), otherwise, Bunbun just eats them
What's the garden like where you live?
