Leaves densely clustered; opposite and with a broad ciliate sheath at the base in a sparse basal rosette, becoming scattered, alternate and without a sheath on the inflorescences; linear to linear-oblanceolate, to 45 mm long and 3 mm, usually bluntly acute, rarely rounded. Inflorescence terminal, with widely-spaced small tubular white flowers. Flowering between June and November. Fruits are woolly fruit with 2 mericarps. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between October and January. Collect maturing fruits, those turning pale straw colour and contain hard seeds inside. Collect individual fruit or collect the whole plant. Place the fruits/plant in a tray and leave to dry for two weeks. Then rub the fruits gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. 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.
