Thanks folks, another mystery solved.correct for ten points wpc.
so i plant this stuff every where i can its not quite as hardy or vigorus as normal purple buddlia but it better for the girls
I'm happy to send you a few hardwood cuttings later in the year, I hack it back each year so I'll keep a few bits to give away.Hmm wonder where I can find one of those buddleas. I have seen one somewhere. At the allotment i am renting there is a bank above my patch. I was strimming it and there is the ordinary buddlea. As the allotment is going to be one of my apiaries I want to put nectar plants all round and over as much as the owners land as possible. I think he would probably appreciate a bit of colour rather than just the nettles and docks that are around at present. Those buddleas would be just right for that bank.
