Plant description

Much-branched woody and woolly perennial herb to 40 cm high. Leaves sessile, oblong to narrow-obovate to 30 mm long and 8 mm wide, apex acute, margins crinkly. Flower-heads terminal on slender naked peduncles to 8 cm long, heads to 20 mm diameter, involucre spreading from base, white to pale pink. Flowering between May and September. Fruits are dry daisy head to 20 mm wide. Seeds are narrow cylindrical brown achene to 2 mm long and less than 0.5 mm wide with a feathery pappus to 6 mm long. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between September and November. Collect heads that are round and brown. 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 long, fat 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 low, at 30%. This may reflect the low seed set of daisies or maybe due to the timing of the seed collection. Seeds are non-dormant, viable seed should germinate readily.
