They might bloom. Mine reseed themselves and grow with no help from me. They were late to sprout this year, but have been blooming now for about a week or so. They often continue to bloom through early to mid-June some years if I keep them deadheaded. Yours likely will bloom if May stays cool and mild ,but are less likely to bloom if it gets hot early.

Mine reseed too although not as much as formerly because I didn't let as many go to seed last year. Mine have been blooming for only a few days. I have seen very short ones bloom so maybe yours will at least bloom some.

This is Barbara, Neil's wife. Mine reseed too. But to start them in the beginning, I just throw the the seeds where I want them between late July and October. I've never "planted" them. They are profuse.

Haha ... I had no idea what I was doing. I should've done more research. Maybe I better start on next year :)
