About 40 species of annual and perennial grasses spread throughout the temperate and alpine zones. They are typical grasses in leaf with somewhat flattened, simple flower spikes, each spikelet bearing long, straight whisker-like awns directed upwards, so that they look rather like a two-dimensionally flighted arrow or dart.
The species described are elegant, attractive and neat enough to justify a place on the rock garden or a pan in the alpine house. Well drained soil and a sunny site will be essential. Propagation by seed or division in spring. It might be wise to keep a careful eye on them during their first year or so in case they seed around over exuberantly.
