Cinda, it makes a great rock garden plant and it is hardy to zone 5. Would love to see photos of yours when you get one. There are some really colorful hybrids that I've seen on the internet.
I found this jewel last fall. I have to admit I was worried if it wouldn't survive our freezing and thawing and torrential rains the lasting several months. It doesn't seem bothered by it at all. I do think I will have to give it water once in awhile during our drought time (July, Aug & Sept.). I look forward to seeing it mature.
This plant gives year round interest and really wows me when in bloom.
