Plant description

Erect perennial herb to 50 cm tall with several stems, usually branched, with dense woolly hairs. Leaves oblanceolate, narrow, flat, covered with soft thick woolly fairs. Flowers white or pinkish daisies. Flowering between September and December. Fruits are white, papery daisy. Seeds are yellow or pale brown seed to 1 mm long and 0.5 mm wide, covered in tiny tubercules with a long pappus at one end. Seed embryo type is spathulate fully developed.

Seed collection and propagation

Collect seeds between November and January. Collect daisy heads that are drying off, easily removed by hand. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Viable seeds will be round and hard. 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 average, at 60%. Seeds are non-dormant, viable seed should germinate readily.
