It's kind of a battle trying to keep some around the yard, but not letting them get out of hand. But the butterflies love them so much, I can't bring myself to eradicate them. Not that I think I could eradicate them to begin with. Plus, as a native plant lover, I realize they were here way before me and obviously serve a purpose in my ecosystem. Luckily, I'm on a corner lot so I can kind of let them grow down by the street and no one cares.
Glad I could help with the article! Even I was surprised by the variety of butterflies I had pictures of on this plant!
