I'd take to whole spent bloom head when gathering the seed - since it is really little

Greg you don't remember what the seeds looked like do you?

Nope they seemed too small to see (but then again I wasn't really looking for them) I wish these were more readily available, I don't understand why they aren't since mine bloomed alot and there seemed to be lots of seed (I'm just not a seed person lately, so didn't pay attention)

Okay, I'll try to get some photos of seeds.

I am wondering if any of you have debudded the plants to get them to multiply vegetatively?
The seeds seem hard to come by, so maybe this would be a way of propagating them?

Caroline, I did not try it this time around. I wish I had, but I was afraid of losing the plant and having no seed. If I can get several plants from the seed I will give the debudding method a try.

I been reading what I can find on these plants, what I did see they are biennials so debudding is probably not going to work. I'm beautiful then just died during the winter last year. I guess it didn't get the right conditions to bloom here in my garden.

This time around I kept mine in a container on the covered deck, with first have day sun and very limited on water through the winter seasons. Seems to work very well.
