Grass Category
Invasive/Weed Grass, Ornamental, Erosion Control (incidental)

About This Grass
An upright or decumbent grass reaching 15-40 inches. It is most recognizable by its fluffy, reddish-pink to rose-colored feathery panicles that turn silvery-white as they age. Stems are slender and often branched at the base.
Blade Characteristics
Blades are 2-5mm wide, flat or slightly folded, linear, and tapering to a fine point. Color is a light to medium green, sometimes with reddish tints at the margins. Ligule is a fringe of hairs; auricles are absent.
Root System
Fibrous and relatively shallow. It establishes quickly from seed but does not form a dense sod or significant thatch; easy to pull manually.
Growing Information
Origin Region
Native to Southern Africa; naturalized across tropical/subtropical Americas, Australia, and Hawaii
Growth Habit
Bunch-type, slightly decumbent, sometimes rooting at the lower nodes (weakly stoloniferous)
Sunlight & Water Needs
Full Sun (highly light-demanding). High drought tolerance; thrives in disturbed, sandy, or rocky soils with low moisture and neutral to acidic pH.
Mowing & Maintenance
Not traditionally mowed. Low maintenance if used ornamentally, though it requires frequent removal if treated as a weed. Responds to disturbance with rapid seeding.
Special Characteristics
Excellent salt tolerance and colonizing ability in poor soils. High seed production. Distinctive pink inflorescence is its primary identification feature.
Ecological Information
Introduced/Invasive in many regions. It outcompetes native grasses following fires or soil disturbance. Provides minimal wildlife food value but can provide cover for small insects/reptiles in barren areas.
