Can’t remember what this is, any ideas?
I have several thick clumps of the plant in the photo. I guess I must have liked it as there are several dotted around. Apparently Lilly beetles love it too as I have just dispatched a bunch I found nibbling the new growth. Any ideas what it is? Also there is new growth both on the original stems and underneath, should I keep both or cut out the old growth?
