Plant description

Erect perennial herb or subshrub to 60 cm high, aromatic with stems and branches covered in cottony or cobwebbed hairs. Leaves very variable, often dimorphic; those of successive seasons or of vegetative and flowering stems differing in length and tomentum; linear to oblong, mostly to 50 mm long and 4 mm wide, acute to apiculate; base broad, margins flat, recurved or revolute; surfaces both grey-cottony or upper surface glabrescent, sometimes scabrous. Flower-heads in clusters with golden-yellow or brownish daisy-flowers. Flowering between October and December. Fruits are pale brown fluffy daisy-head. Seeds are brown ovoid seed to 1 mm long and 0.3 mm wide, covered in small tubercules and with pappus bristles finely barbellate and white for two-thirds of their length, upper third bright yellow. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between January and March. Collect whole heads that are brown and fluffy or collect just the seeds by plucking it off with your fingers. Mature seeds are easily removed. Place the heads in a tray for a week to dry. Then pluck the seeds from the head with your finders. Viable seeds will be fat 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. From one collection, the seed viability was low, at 15%. Seeds are non-dormant, viable seed should germinate readily.
