Non-invasive Buddleia varieties?
Asked December 14, 2020, 3:51 PM EST
Online I saw that Buddleia Lo and Behold do not set seeds and are therefore non-invasive. Have you done research on these varieties or others?

There's a lost of sterile butterfly bush cultivars from the Oregon Department of Agriculture:
Cultivars on this list have been researched and don't spread aggressively by seed. There are still butterfly bush plants available that spread by seed, especially for plants purchased online.
If you choose to plant a butterfly bush, choose varieties at the link above.
