Plant description

Very slender, erect, tufted annual to 45 cm high with smooth or finely scabrous culms smooth. Leaf-blades folded, almost capillary, to 20 cm long and 0.5 mm wide; ligules obtuse, lacerated, mostly to 6 mm long. Inflorescence an open panicle usually at least half as long as entire culm, branches widely spreading at maturity and often purplish. Flowering between October and March. Fruits are compact, purple-brown fruit-spike. Seeds with one short awn. Seed embryo type is lateral.

Seed collection and propagation

Collect seeds between November and April. Use hands to gently strip seeds off the mature seed spike that are turning purple-brown. Mature seeds will come off easily. Alternatively, you can break off the whole seed spike. Place the seeds/spike in a tray and leave to dry for two weeks. No further cleaning is required if only seed collected. If seed spikes collected, use hand to strip off the mature seeds. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seed viability is usually high.
