Plant description

Erect branching shrub to 2 m high with sticky simple, broad-lanceolate to ovate leaves to 60 mm long and 25 mm wide. Fruits are maroon balloon-like three-winged fruit. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between September and October. Collect winged capsules that contain hard black seeds, usually when capsule is large and turning red or brown. Place capsules in a tray to dry for 1 to 2 weeks. Then rub the capsules 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. From one collection, the seed viability was average, at 70%. This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
