Perennial herb to 60 cm high with unbranched, short, erect stems. Leaves all near the basal, sometimes forming a rosette, sessile, oblanceolate to spathulate, shallowly obtuse-lobed, to 6 cm long and 1.5 cm wide. Inflorescence solitary on a long stalk with large white ray florets and yellow disc florets. Flowering between August and October. Fruits are brown daisy head. Seeds are flat brown, ovoid seed to 3 mm long and 2.5 mm wide, with a broad wing and scattered hairs on the margin. Central part covered in scattered hairs and a minute pappus at one end. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between October and December. Pick heads that are maturing, drying off, with brown seeds that dislodge easily. Place the seed-heads in a tray and leave to dry for a week. Then gently rub the heads 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. From one collections, the seed viability was average, at 55%. This species may have physiological dormancy that needs to be overcome for the seed to germinate. Germinates well at cool temperatures (between 7 oC and 17.5 oC).
