Leaves spreading, linear, more or less decurrent; obtuse, to 10 mm long and 1 mm wide; upper surface glabrous or subglabrous, green, lower surface with creamy hairs, almost wholly obscured by the recurved margins. Inflorescence a leafless pyramidal spike; dense to loose, erect to drooping, with buff-coloured flowers. Flowering between January and April. Fruits are loose golden daisy heads. Seeds are brown cylindrical seed to 1 mm long and 0.4 mm wide, with long white pappus at one end. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between March and June. Collect heads that are matured,golden brown and contain brown seeds. Place the heads in a tray for one to two week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a sieve to separate any unwanted material. Viable seeds will be small and brown. 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. Seeds are non-dormant, viable seed should germinate readily.
