I'm embarrassed to even ask this question, but I can't seem to find the answer online or in my books. I was outside today trimming Ornamental Grasses and Autumn Joy's for spring, but I'm not sure what to do with the Dragon's Blood Sedum I planted last year.

I would think that I should cut them down, as you do most (or all?) perennials, but I don't want to kill them as I planted nearly 2 dozen plants! Thanks in advance for your help!
