Plant description

Shrub or small tree 6 m high, with corky bark; glabrous except for young shoots with white hairs. Leaves alternate, narrowly ovate, to 8 mm long and 3 mm wide, acuminate-acute and inflexed at the apex; obscurely 3-nerved and punctate-glandular below. Inflorescence a terminal globular head to 15 mm wide, generally wider than long, with 4–9 pink to purple flowers. Flowers in spring. Fruits are grey-brown scaly spherical capsule to 6 mm diameter; truncate, slightly compressed; in globular clusters on leafy or woody stems. Seeds are dark brown ovoid or pyramidal-shaped seed to 1.2 mm long and 0.7 mm wide. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between January and December. Collect capsules that are large and hard, with closed valves. Place the capsules in a tray and leave to dry for at least two weeks or until all the valves are open. Then place all the capsules into a bucket with a lid if possible and shake hard to dislodge the seeds from the capsules. Use a sieve to separate the seeds from the capsules. The fine material will contain the seeds and other flowering material. It is very difficult to separate the seeds from this other material as the size, shape and weight are very similar, however the seeds will be a darker brown. 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 100%. Seeds are non-dormant, viable seed should germinate readily.
