They have been in their respective spots for 2 years now. They are about a foot across, size wise. They both get approximately half day sun, but they have never flopped,.. thankfully!
Usually when I split a root mass, I just split the *back* side away and replant. Then it doesn't usually show. These plants are viewed all the way around however, so I'm taking your advice. I'll just clip small stems and try to root them.
After I pot up the cuttings should I set them in partial shade until they root?
