I grew them in my Pennsylvania garden for a couple of summers. They are a neat, interesting plant (kind of floppy) and I loved the gray/blue leaves and blue/purple flowers. I'm not sure how well they'll do with hot, wet summers but I think it's worth a try. Maybe plant them where they'll get some shade.

I ordered them from Annie's Annuals one year. I had them in full sun. They did great until July, August when it got too hot and they died. Maybe if I had put them in an area with morning sun, afternoon shade they would have been OK. I do want to try them again in that setting.
