Name derivation:
Luzula possibly from the Italian 'luzziola' meaning sparkle or a fire-fly or from the Latin 'luxulae 'meaning light; probably alluding to the sparkling and quivering character of the heads when wet with dew. flaccida from the Latin 'flaccidus' meaning slack or flaccid; referring to its drooping leaf-blades.
Found in the southern Mount Lofty Ranges and the lower South-east in South Australia, growing in moist rather shady sites in grassy woodland or open grassland. Also found in Queensland, New South Wales, Victoria and Tasmania.
Native. Rare in South Australia. Uncommon in Queensland. Common in the other states.

Seed collecting:
Collect fruits either by picking off the mature heads, those turning brown and come-off easily or break-off the whole spikes.
Seed cleaning:
Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Be careful, as the seeds are very small. Seeds are brown and hard. 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:
From one collection, the seed viability was high, at 100%.
