General Landscape Uses:
Primarily recommended for natural landscapes and habitat restorations. Also provides a good base for wildflower gardens.
Ecological Restoration Notes: An occasional understory grass in a wide variety of pinelands. Rarer in the southern part of peninsular South Florida in marl prairies.
Availability:
Commonly available at native plant nurseries in central Florida.
Description: Medium to large herbaceous grass.
Dimensions: Typically 2-4 feet in height; to 6 feet when in flower. A clumping grass about as broad as tall except when flowering.

Soils: Moist to dry, well-drained sandy soils, without humus.
Nutritional Requirements: Low; it grows in nutrient poor soils.
Salt Water Tolerance: Low; does not tolerate flooding by salt or brackish water.
