Hardy Pampas Grass has an upright to open habit with large, white plumed flowers. Flowers appear in fall from late September to late October. Because of its large size it is very effective as a specimen plant or screen. It forms large clumps up to about five feet in diameter. It is often used as a substitute for pampas grass in northern growing areas. The stems are weaker than pampas grass and have a tendency to break in high winds. It performs best in as sunny site in moist, well-drained soils. Wet sites shorten its life considerably and leads to extensive winter injury.
