Pennisetum clandestinum Hochst. ex Chiov. |
The tropical grass species Pennisetum clandestinum is known by several common names, most often kikuyu grass, as it is native to the region of East Africa that is home to the Gĩkũyũ tribe. Because of its rapid growth and aggressive nature, it is categorised as a noxious weed in some regions. However, it is also a popular garden lawn species in Australia, New Zealand, South Africa and the southern region of California in the United States, as it is inexpensive and drought-tolerant. In addition, it is useful as pasture for livestock grazing and serves as a food source for many avian species, including the long-tailed widowbird. The flowering culms are very short and "hidden" amongst the leaves, giving this species its specific epithet (clandestinum).
Pennisetum clandestinum is a rhizomatous grass with matted roots and a grass-like or herbaceous habit. The leaves are green, flattened or upwardly folded along the midrib, 10-150 millimetres long, and 1–5 mm wide. The apex of the leaf blade is obtuse. It occurs in sandy soil and reaches a height of between 70 and 150 millimetres. The species favours moist areas and frequently becomes naturalised from introduction as a cultivated alien. Rooted nodes send up bunches of grass blades. It is native to the low-elevation tropics of Kenya and environs, where it grows best in humid heat, such as the wet coastal areas.
The description of this species was published by Emilio Chiovenda in 1903, and acknowledges an earlier, invalid, description made by C. F. Hochstetter.
It has been introduced across Africa, Asia, Australia, the Americas, and the Pacific, where it is subject to eradication through management practices. The ease of cultivation, and the thickly matting habit, have made this species desirable for use as a lawn. In southern California in the United States, the grass is commonly used on golf courses since it is drought resistant and creates challenging rough. The famed Riviera Country Club and Torrey Pines Golf Course both use this grass and host tournaments on the PGA Tour. Other minor golf courses in southern California have kikuyu grass, many are in Long Beach: Lakewood, Skylinks, Big recreation, Little recreation, El Dorado, and others.
