Plant description

Perennial herb to 60 cm high, with an underground rhizome. Stems sparsely branched, erect, rather weak, glabrous. Leaves radical and cauline, sessile, narrowly lanceolate to linear, entire, narrowed at the base, acute, to 9 cm long and 2.5 mm wide, glabrous, with a prominent mid-vein. Large solitary white daisy flower on a long stalk. Flowering between September and January. Fruits are brown daisy-heads. Seeds are brown, semi-flat ovoid seed to 2mm long with a smooth, broad margin, surface covered with tubercule and pappus reduced to a microscopic rim. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between November and June. 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 three collections, the seed viability was average to high, ranging from 65% to 90%.
