Has anyone heard of this plant or know anything about it? I got it free from my nursery & the don't know much about it at all. They are giving it out free & asking us to give them feedback on it. All I know is that it is a perennial for our zone 4 and that it is to be planted in a sunny area. It is suppose to have compact button like flowers, but I don't know that for sure. When it flowers I'll get a photo.
