'Stellar Pink'?, 'Summer Beauty'? I googled ' buy pink butterfly bush' and those 2 were the only pink cultivars that weren't dwarf selections. These are upright growers, another pink cultivar Grand Cascade has a more weeping habit.

im not sure i would call that pink ... OP will probably have to tell us how precise the pix are to actual color ....

It looks more like lavender Ken, so maybe just google purple or lavender butterfly bush, and then hit SHOPPING. I don't know if there's enough differences (if any) between these cultivars to be able to get the precise 'name'. imo

I'm not sure it is anything other than an example of the species Buddleia davidii. They self seed very freely in areas where the climate suits (like VA) and coloring can be quite variable.

That is so possible gardengal. More background information would have clarified if it was a purchase, or a self sown plant.

The self sowers do vary and even throw up a white occasionally. Impossible to name the OP’s specimen from the pictures, even if it has a name.

It was planted by a nursery two to three years ago. Thank you.
