Voices in the Dark
This year the clump has decreased and the flowers are smaller.
What causes this?

They are very pretty, Ruth. did Voices In The Dark have a great year last year? I have noticed that some of mine (not all, but many) will have a couple of down years after an exceptional bloom year. I lost a good bit of one of my excelent plants,and I blame it on the very cold winter.

Voices in the Dark is a really pretty Shooter hybrid. It's listed as a "sev" so that says not much as far as winter hardiness in your zone. I know your winter was colder then normal, but just my guess is it's not winter kill that's the problem. Could be cultural. Pot it up in some really good quality and well drained potting mix if it looks like you might be going to loose it and see if the change in growing medium helps any. If you dig it up you could also get a peek at what's going on with the roots...Maryl

Voices in the Dark is really pretty. I have the same symptoms with several of my clumps, and I blame it on the long, cold winter coupled with an extremely dry month of May.
