Gardeners' Notes:

What a pleasant surprise!
I planted a small pot of this last fall, just before an 18 degree freeze. It died back, but this summer, it came back beautifully. Perhaps 12"-15" in diameter, and about 18" tall, it bloomed from June through August, and is just slowing down now.
Everyone should have this very lovely deep pink color in their garden.

Update: It's her third summer, and she's 2.5 feet wide. Ignore the spacing above. Still a stunning plant. Blooms until late fall if pruned and happy. It would make a nice low hedge in 3 year's time. Mine's about 2.5 feet tall, too.

Didn't last past its first winter - could be not enough sun or too much moisture.
