Plant description

Small annual to 22 cm high, with woolly to glabrescent, reddish, wiry stems that are sparsely branching. Leaves woolly with basal leaves dying early. Stem leaves lanceolate to 4 cm long and clasping the stem. Involucral bracts with linear glandular claws and broad ovate, smooth lamina to 4 mm long. Florets pale yellow to yellow. Flowering between August and October. Fruits are white fluffy daisy-head. Seeds are brown ovoid seed to 2.5 mm long and 1 mm wide, smooth with few short feathered-like pappus at one end. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between September and December. Collect heads that are fluffy. Either pick off the whole heads or use your finger and pull off the seeds from the head. Mature seeds will come off easily. Place the heads in a tray for a week to dry. No cleaning is required if only pure seeds are collected. If heads are collected, then rub the heads gently with your hands to dislodge the seeds. Viable seeds will be fat and hard. 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 eight collections, the seed viability was high, ranging from 90% to 100%.
