Hmmm.... in truth I'm worried about all my perennials this year. Last year we had such an awful drought, coupled with extremely hot temps. Things went down the tubes fast in late summer. I hoped they were just going dormant a little early, but it really could have been the beginning of their demise. By fall the only things I my yard that looked good were my coleus. I did take cuttings of those and so far, I haven't killed those yet.
