- 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. However, it is also a popular garden lawn species in Australia and South Africa because it is cheap and drought-tolerant. In addition it is useful as pasture for livestock grazing. Pennisetum clandestinum is a rhizomatous plant, in the Poaceae (grass) family, that has 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 to 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, unvalidated, 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. The aggressive colonisation of natural habitat has resulted in this grass becoming naturalised in regions such Southwest Australia. It has high invasive potential due to its elongate rhizomes and stolons, with which it penetrates the ground, rapidly forming dense mats, and suppressing other plant species. It grows from a thick network of rhizomatous roots and sends out stolons which extend along the ground. It can climb over other plant life, shading it out and producing herbicidal toxins that kill competing plants. It prevents new sprouts of other species from growing, may kill small trees and can choke ponds and waterways. It is resistant to mowing and grazing due to its strong network of roots, which easily send up new shoots. It springs up in turfs and lawns, and can damage buildings by growing in the gaps between stones and tiles. The plant is easily introduced to new areas on plowing and digging machinery, which may transfer bits of the rhizome in soil clumps. While the grass spreads well via vegetative reproduction from pieces of rhizome, it is also dispersed via seed.
- Pennisetum clandestinum es una especie perenne tropical de Poaceae con varios nombres comunes, kikuyo, grama gruesa, pasto africano, que proviene de la región de África Oriental, hogar de la nación Kĩkũyũ. Posee rápido crecimiento y agresividad, por lo que se lo categoriza como una maleza en algunas regiones (estando prohibida su presencia en áreas de EE. UU.. Sin embargo, es también un pasto popular de céspedes en Australia y en Sudáfrica debido a su baratura y tolerancia a sequía. Además es muy usada como pastura de ganadería, con calidad baja, pero muy rica en proteína. Fue introducida a través de África, Asia, Australia, América, y el Pacífico. Tiene alto potencia invasivo debido a sus agresivos rizomas y estolones, con los que penetra la tierra, formando rápidamente densas matas, y suprimiendo a otras especies. Posee matas de hojas laminares, bien angostas y de 11 a 15 cm de longitud; alcanzando como planta 10 a 13 dm de altura. Es nativa del trópico de baja elevación en Kenia y alrededores, creciendo en calor húmedo, como ocurre eu sus áreas costeras húmedas. Puede trepar sobre otras plantas, sombreándolas, y además produce toxinas herbicidas que matan otras plantas competitivas. Puede matar hasta pequeños árboles, y sobrevivir aún en charcas y corrientes. Es resistente al pisoteo y al pastoreo, debido a su fuerte red de raíces, que fácilmente crea renovales aéreos de tallos. Se dispersa por trozos de rizomas y por semilla. Se establece a partir de trozos de estolones plantados a 5 × 5 dm .
- Pennisetum clandestinum, le kikuyu, est une espèce de plante de la famille des Poaceae (Graminées). Elle est originaire d'Afrique centrale et est très utilisée comme gazon dans la région méditerranéenne.
