I think this is such a lovely plant...green and white variegated. Somehow I have had the impression that it is highly invasive. I picked apart a clump of it last spring and sprigged it along the front of my white border. By fall, I thought the armadillos had done it in, but tiny little clumps are coming back. What's your experience? Is it invasive, or does it just need a little tidying each year to keep it neat? Is it evergreen?
Thanks for your input!
