Could you please show the flowers close up? It looks as if it could be Buddleja alternifolia but not showing its natural arching habit because of ill-advised pruning.

Here's a close up:

@floral_uk - yes, it is a buddleia alternifolia. We bought a house 2 years ago with large gardens but head-scratching placements. This beauty is in a back corner of one of the beds that get am sun that turns into shade around noon and then gets late day sun around 5-6 to sunset. When we first moved in and cleared out the 5' tall weeds that had overtaken the beds (the house was vacant for over 3 years), there wasn't a single bloom on this plant. The second year there was one. This year - you can see how many blooms there are now. I read that this can be "sloppy looking" which I can see how that is. I was trying to prune it to be bushier, but I've seen pictures of buddleia alternifolia (fountain butterfly bush) where the branches have a weeping or fountain-like look. That will now be my goal.

Yes - this one will never be bushy. It's natural growth habit is very lax. In fact it might even need a stake to keep the main stems up straight so the 'fountain' can cascade down effectively. Yours appears to be growing back into its natural form now. It can look great planted on top of a retaining wall and allowed to hang down. When not in flower it is a bit drab but still provides a nice foil for other stuff.
