Here is some info on these flowers I got off the internet. Grows in zones 3-10, so yes it does look like they will grow for you :) also says easy to grow from seed. Likes full sun or partial shade. Can be started indoors in the winter to be transplanted outdoors in spring, or can be sown directly into ground in spring and summer. Perennial, easy to grow, requires very little care. Long flowering. Grows to 36 inches tall. I have this plant, it is beautiful. The seeds I have up for auction I harvested from my own plant. Hope that helps :)
