About This Grass

Forms a flat, circular mat radiating outward from a central taproot. Features small, opposite oval leaves often with a dark reddish-purple spot in the center and milky sap when broken.

Blade Characteristics

Not a grass; has small, oval, opposite broadleaf leaves rather than grass blades.

Root System

Deep central taproot with branching surface stems, making hand-pulling necessary to remove completely.

Growing Information

Origin Region

North America, widely naturalized globally

Growth Habit

Prostrate, mat-forming annual weed spreading via surface stems

Sunlight & Water Needs

Thrives in full sun and dry, compacted soils; highly drought-tolerant once established.

Mowing & Maintenance

Low-profile growth allows it to survive low mowing; controlled best by pre-emergent herbicides and hand-pulling.

Special Characteristics

Produces a milky, irritating latex sap when broken; highly prolific seed producer capable of invading thin turf and landscape beds.

Ecological Information

Acts as a troublesome agricultural and turf weed, though provides minor ground cover in disturbed native soils.
