I may be wrong, but it looks like a Leycesteria formosa. A beautiful shrub in the right place. A thug in the wrong garden. It does sucker at the base creating a bushy shrub, especially if pruned to clear out the dead bits. The common name that I know it by is Himalayan honeysuckle, but also pheasant berry. It used to be used, planted in wide sections along the sides of woods and fields to encourage pheasants. They use the bush as cover, but like a lot of birds eat the berries. This is how it gets propagated around the area.

I agree it's Leycesteria formosa, I also know it as Pheasant Berry, never heard it called himalayan honeysuckle before.

Agreed, and the flowers are really nice, julien.

Thanks for the very helpful info!
