I've got some plants I have grown from seed, looked in the cold frame, and they seem to have come through the winter (So far). Frost this morning.
This is the third year, and don,t know how old they have to be to flower, only about 4" to 6" high now. I also don't know if they come true from seed, I am assuming not, and waiting for a nice hybrid. It's half the fun.
