Plant description

Tall weeping perennial grass with erect or arching culms to 120 cm tall. Leaves mostly basal with blades narrow, fiat or filiform, scabrous on the edges. Inflorescence a 25 cm spike with numerous fertile spikelets on each. Flowering between July and December. Fruits are brown spike-head containing numerous individual seeds.

Seed collection and propagation

Collect seeds between October and February. Use hands to gently strip seeds off the mature seed spike that are turning straw colour. 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.
