Mine's not the delaviyii version, but the other one, whose name I forget!
It looks exactly the same as delaviyii, only shorter.
It's looking rather sorry for itself, although it has flowered and there are a few buds still to open, but I had a red spider more infestation a few weeks back and its leaves were affected somewhat.
Do thalictrums benefit from a haircut around this time and if I chop it, will it re flower this year?
thanks to all you gardening peeps more knowledgable than me
