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 Kĩkũyũ tribe.
Because of its rapid growth and aggressive nature, it is categorised as a noxious weed in some regions.^[1][2]
However, it is also a popular garden lawn species in Australia, South Africa and Southern California because 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.^[3]
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.^[4] It occurs in sandy soil and reaches a height of between 70 to 150 millimetres. The species favours moist areas and frequently becomes naturalised from introduction as a cultivated alien.^[5] 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.
