I've never grown it, but I know its growth habit - it does trail and droop, so I think you've done absolutely the right thing, otherwise it can make a rather messy thicket of stems with tumbling new flowering growth on the outside.Unlike the more common Buddleia davidii, I expect you know this one needs pruning immediately after it's flowered - cut back flowered stems by at least half and reshape if necessary. And please post a photo when it's in flower!

it is a beautiful shrb but i have never had much success with it. post the pictures as you go. sounds really good.

I don't know a lot about them but my understanding is that,they flower on last years stems, you should prune old flowering stems about a third,immediately after flowering, by the way do not prune in spring as with other buddlea, older stems cut down to the ground, and make shore that it has a good thick stake for surport.

We grow it as a thicket as we have enough room to do that. The flowers are not spectacular but there are plenty of them and bees adore them. Never actually bothered pruning ours as I wanted it to get big. Certainly hardy if it survives in our garden.

Take lots cuttings from the bits that you prune off. I'm sure everyone will want one. It is impressive when in flower and attracts lots of comments. No-one knows what it is!

There is a lovely monograph on Buddlejas with lots of species I wish I could a. grow or b get hold of. Buddlejas by David D. Stuart. RHS Plant Coolectors Guide. One in particular is a real want. B. fallowiana. The leaves and stems are pure white with hairs. It has flowers like B. alternifolia. There is a magnificent specimen at Powys Castle Gardens. They never have any on sale though. Despite its looks it is supposed to be hardy.

Thank you everyone for your goo advice "as always!"

I will keep you updated with it's progress and a pic too!

good advice too! "what is goo advice? it's knowing what to do for a sick cream egg!..................
