Neal, I'm going to have to dig up some perennials, too, to try to remove the larkspur volunteers. They're between and among a couple of coreopsis moonbeam, and so many in a liriope that I might just give up on the lirope. They're within the area where my butterfly weed will emerge, too, but I know I can't move the butterfly weed. I'll just have to do my best. Hopefully, after the rain we're to get tonight and tomorrow, those larkspur might be easier to remove.
I put down a lot of cardboard yesterday in attempt to smother larkspur, but unfortunately ran out of cardboard before I ran out of larkspur...
