    Very slender leaves that are often blue-green. Stays in a dense clump. The flowers and seed heads are like eyebrows or combs, on stems that rise high above the leaves. It's one of my favorites.

    A warm-season grass. It grows in summer while temperatures are warm, and the leaves turn straw yellow through the winter. It has very low water needs once established, because it uses the C4 carbon fixation pathway, which is very efficient in hot and dry conditions.
