Very showy upright grass with seed heads that last well into the winter. Semi evergreen with medium green foliage. Flowers appear on 3-4 foot stalks above the foliage in May-June that bleach to a buff color.

This is a clump forming cool season grass.

Prefers moist rich soil in full sun but will tolerate heavy soils and and heat if watered. Shade tends to cause the foliage to flop over. Cut back in spring before new growth starts.
