Charming Heart has done acceptably in 7A, but not particularly well. I planted it April 1 of this year, and it brought me a few blooms as of June 30, but just that...a few blooms. Like alilyfan, it didn't reach its height and grew to about 28". But it's a first year DL for me, so I'm waiting until next year to proclaim it as not a successful DL. It's a dormant, so I'll be interested to see how it does after this winter.
