Mine all bloomed in the Spring, and they weren't very tall. Some get to 4 feet tall or more! Some of the summer blooming ones are hardy to zone 4. There are many to pick from, for every planting situation. Some like more shade, and others like full sun. I don't know why I didn't think about getting some for here. They would be perfect!
I think they are all known as Windflowers though. Not positive, but pretty sure.
