Pennisetum clandestinum

Kikuyu, in Latin Pennisetum clandestinum, is an evergreen grass of subtropical origin used as an alternative to turf in regions unaffected by heavy frosts. It has broad and hairy foliage and forms a dense, greasy-looking carpet that withstands trampling and drought if not too prolonged. The plant is sensitive to heavy frosts and its foliage may turn yellow in winter in the case of persistent frost. This grass, which tolerates salt spray, will work wonders on the Atlantic coast of our country, or in slightly watered gardens in the Midi. The seeds are sown in spring after frosts, in the sun, in a rather rich and well-prepared soil, preferably not too chalky.

Pennisetum clandestinum belongs to the large family of Poaceae, it is a perennial grass native to Central Africa frequently used in green spaces in Mediterranean climates, as it appreciates heat and has relatively low frost resistance. Kikuyu takes a little time to establish, but it has long trailing rhizomes that can quickly colonize the area once well established. Its foliage consists of fairly wide leaves, covered in hair and of a bright green colour. If not mowed, it forms a carpet 30 to 60cm (12 to 24in) high, which persists in mild winters. This plant adapts to dry summers: a lack of water slows down its growth, greatly reducing the number of mowing required in summer. By reducing water inputs, it is possible to maintain the carpet at an average height of 8 to 15cm (3 to 6in). It is advisable not to mow a Kikuyu lawn too often or too short. It can be mixed with semi-trailing fescue seeds for faster establishment.

Composition:

• 100% Pennisetum clandestinum

Usage and dosage:

• Sowing rate: 10 to 15g/m2

In our driest regions, watering once a week can be beneficial to maintain a vibrant green colour in the Kikuyu lawn. The plantation should be regularly watered and cleared of "weeds" during the establishment period. Once established, the plant can become invasive in hot and humid climates. Ideal for small city gardens, kikuyu is useful for covering slopes, effectively stabilizing the soil and limiting erosion phenomena.
