Plant description

Shrub to 2.5 m tall, with erect branches. Leaves opposite, semi-terete, usually with a fine recurved point; to 7mm long. Flowers solitary or rarely in pairs; axillary, 5 white petals. Flowering between September and January. Fruits are woody grey-brown capsule with 3-5 valves. Seeds are seeds are angular, pale-brown, less than 1mm.

Seed collection and propagation

Collect seeds between February and April. Collect mature capsules, those that are hard with non-open valves. Place the capsules in a tray and leave to dry for a week or two. This allows the valves on the fruit to open and release the seeds. Separate the seeds by placing all the materials into a bucket and shaking it to dislodge the seeds. Pass the material through a sieve to separate the unwanted material. The finer material will contain both seeds and frass usually distinguishable from each other. With finer sieves, the seeds can be separated from the frass but this is not essential for storage or propagation. 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 high, at 95%.
