This is a beautiful and fairly well-behaved plant here in Middle Tennessee although it does also spread by rhizomes and can become invasive. However, it is easy to cut back and well worth the effort. The variegation is lovely and the interesting seed heads nodding in the breeze are delightful. I enjoy it very much.
