- Pennisetum ciliare is a perennial bunchgrass that can grow 3.9-59.1 in. (10-150 cm) tall in thick mats.
- The leaf blades are bluish-green in color, mostly flat, ranging from 1.2-11.8 in. (3-30 cm) long, with soft hairs on the upper surface.
- The inflorescence is generally cylindrical in outline, 0.8-5.5 in. (2-14 cm) long, and can be purple, gray or yellowish. The bloom period occurs during mid summer.
- Seed-head can vary from reddish or purplish brown when the seeds are young to a tan color when the seeds are mature.
- Ecological Threat
- Pennisetum ciliare grows densely and crowds out native plants of similar size. It’s dense roots and ground shading prevents the germination of seeds of other species. Pennisetum ciliare is native to Africa, Asia, and Europe.
