Plant description
Greyish-pubescent perennial with creeping stems, rooting at the nodes. Leaves on long petioles, reniform to oblong-orbicular, to 25 mm long; rounded to emarginate, base cordate. Inflorescent small solitary pale greenish-yellow flower in axils of leaves. Flowers throughout the year but mainly between October and January. Fruits are brown hairy 2 cell capsule.
Seed collection and propagation
Collect seeds between November and March. Collect mature capsules that are drying off, turning pale brown with hard, dark seeds inside. Capsule with viable seeds maybe difficult to find. Sieve to separate any 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.
