This beautiful well behaved grass has the effect of a small bamboo in the northern garden. The leaf blades are in constant movement with the wind.

After a frost it turns a red-mahogany color but falls apart shortly thereafter so the beauty is evanescent. One of my favorites.

Admittedly it does look terrible if allowed to get severely dry but it is tough and is not easily killed. This plant propagates by seed or division.
