Plant description

Annuals herb with decumbent or erect branches to 15 cm long, little- to much-branched; sometimes rooting at nodes. Leaves linear-lanceolate, to -oblanceolate, to 9 mm long and 1.5 mm wide; acute, rarely obtuse or rounded; dorsiventrally compressed, more or less convex above and usually strongly convex below. Inflorescence terminal with white to cream flowers. Flowering between August and November. Fruits are small red-brown capsules at terminal of stems.

Seed collection and propagation

Collect seeds between October and December. Collect whole plants that are drying off, turning red-brown with mature capsules. These will contain very small brown seeds when rubbed with your fingers. Place the plants in a tray and leave to dry for two weeks. Then rub the plants gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Be very careful as the seeds are very small. 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.
