Pennisetum

Fountain grasses are very well named, with masses of flowers, flowing from clumps of mounded foliage. The flower spikes can be coloured, white-cream to red, with conspicuous bristles, hence the latin name Pennisetum,  penna meaning feather and seta, bristle-like. Generally they come from tropical and warm-temperate regions, so do need a full sun, or very light shade, or grow in containers.
