The 'Color Guard' variety doesn't take over. It produces some offsets, but not like the other kind. It also doesn't stick me like the others. It's more soft to the touch. Many people rank it among their favorite plants for year-round color.
Sedum 'Angelina' can be propagated by just pinching small pieces off and stick them where you want them. It's so easy. I even root them in July in full sun. I bought one plant last year and broke it all to pieces and it filled in around my Maple tree completely in one season. It's a good plant!
