A large annual grass with green strappy leaves which can grow up to 2.5 metres. It is native to Africa, and has flower spikes are covered in small, yellowish-green flowers, followed by bushy pale to brown-red flowerheads of edible, starchy grains. The seeds can ripen in the UK if given a long hot summer, but it can also be grown as a tender bedding plant. Grows quickly in moist but well-drained soil, although it is tolerant of dry conditions. Requires a warm, sheltered position in full sun.
