Etymology

Brachyscome from the Greek 'brachys' meaning short and 'kome' meaning hair, referring to the tuft of short bristles or hairs of the pappus. Diversifolia from the Latin 'diversus' meaning different and 'folium' meaning leaf, referring to the species having different shaped leaves on the same plant.

There is an old collection (1934) from the South-east around Lucindale but this population has not been relocated. Also found in Queensland, New South Wales, Victoria and Tasmania. Native.

Plant description

Erect perennial daisy growing to 50 cm tall with hairy serrated basal leaves. Flowers single large white daisy on a long stalk. Flowering between October and November. Fruits are dried daisy-heads containing numerous seeds. Seeds are rectangular brown seeds to 3.2 mm long and 0.5 mm wide, with short hairs at one end. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between October and December. Collect heads that are drying off and turning brown. The hard brown seeds should dislodge easily. Place the heads in a tray and leave to dry for a week. Then rub the heads gently with your hands 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 55% to 85%. This species has physiological dormancy that need to be overcome for the seed to germinate.
