What does it look like?

Plant: Stout, perennial grass, grows in clumps 3 to 4 feet tall.
Leaves: Grayish to bluish green blades, 15 inches long.
Flowers: Arranged in dense cone-shaped heads, 2 to 5 inches long, at the end of a tall flowering stem. Flower heads turn green to creamy white from May to June.

Where is it found?

Coastal valleys, grasslands and disturbed sites such as roadsides. Often found in relatively moist areas but a deep root system allows it to survive in drier areas. It is common in parts of the western Santa Monica Mountains including Rancho Sierra Vista, Rocky Oaks and La Jolla Valley.

Why worry?

Harding Grass forms dense patches, displacing native plants by depriving them of water and nutrients. In the summer, dry foliage is a fire danger.
