Pogonatherum paniceum

Pogonatherum paniceum (Lam.) Hack. (golden hair grass, jin si cao 金丝草) is a tufted perennial grass of the Poaceae (Andropogoneae) native to tropical and subtropical Asia, from southern China and Taiwan through Southeast Asia to the Indian subcontinent. It typically grows on damp rocks, cliff faces, ravine walls and stream-side boulders from low to mid elevations. Plants form dense, fine-textured tussocks 10–30 cm tall, with slender, wiry culms and short, narrowly linear, soft leaf blades 1–5 cm long. The inflorescence is a slender, golden-tinged, spike-like raceme 2–6 cm long, the spikelets paired with one sessile and one pedicelled, each bearing a delicate, fine, long awn that gives the whole plant a silky, hair-like appearance — the basis of both the Latin and Chinese names. It is also widely cultivated as a miniature ornamental grass.
