Plant description

Decumbent to ascending perennial herb with stems to 50 cm long, with sparse to dense, short hairs. Leaves opposite, ovate to orbicular or reniform in outline, to 2 cm long and 3 cm wide, with hairs on both surfaces, deeply 5-7-lobed or dissected, each lobe divided into 3 narrow lobes. Flowers sometimes solitary or usually paired with bright pink to magenta petals. Flowering between June and February. Fruits are brown fruit to 15 mm long with 5 hairy mericarps. Seeds are dark brown-black subglobular seed with small rectangular cells on the surface

Seed collection and propagation

Collect seeds between October and March. Collect matured fruit, those that are turning brown and the mericarps are starting to curl and peeling off the fruit stalk. Place the mericarps in a tray and leave to dry fro 1 to 2 weeks. If only the mericarps are collected, no further cleaning is required and it can be stored as is. Alternatively, you can clean to seed by gently rubber the mericarps with a rubber bung, then use a sieve to separate unwanted material. Store the mericarps/seeds with a desiccant such as dried silica beads or dry rice, in an airtight container in a cool and dry place.
