Today, after church, I finally got the obedient plant dug up and threw it in the compost. Amazingly misnamed, and a wretched plant. I actually have a pink one, with variegated foliage, but it's not very prolific or strong. It is actually coming back as a handful of growing tips this year, which it didn't do last year, so maybe it will be better. But it's nice to have the white one gone.
I didn't get the big sedum split though. Another day.
