Plant description

Perennial colony-forming herb with fibrous roots; generally evergreen, sometimes dying back over summer to a dormant, stipule-covered bud to 3.5 mm diameter. Stem short, enclosed by persistent leaf bases. Leaves many in a convex rosette; orbicular, peltate attached near the margin, to 2 mm diameter. Central leaves in winter modified to form deciduous propagules (gemmae). Inflorescence very slender, glabrous with 1 4- petalled flower; sepals oblong to elliptic, glabrous; petals elliptic-spatulate, white. Flowering between September to January. Fruits are brown ovoid capsule to 2 mm diameter, erect.

Seed collection and propagation

Collect seeds between November and December. Collect mature capsules, those that are fat, hard, turning brown and contain black seeds inside. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently 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.
