Plant description

Perennial shrub to 3m high, predominantly dioecious, with lower branches decumbent. Leaves broad-elliptic with the lamina to 35cm long and 4cm wide. Male and female flowers on separate plants.

Seeds are shiny brown, circular reniform seed to 2mm wide. Seed embryo type is peripheral

Seed collection and propagation

Collect seeds between January and December. Collect spongy dried fruit either directly from the bush or from the ground underneath. Place the fruits in a tray and leave to dry for one to two weeks. No cleaning is required if only the fruits are collected. The seed can be stored in the fruit or can be clean further. Rub the fruit 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.
