Leptospermum from the Greek 'leptos' meaning fine, thin or slender and 'sperma' meaning seed; referring to the narrow seeds of the type species. Lanigerum from the Latin 'laniger' meaning wooly; referring to the hairy leaves, buds and fruits.
Distribution and status

Tall shrub to 4 m high with small stems smooth and larger stems fibrous, persistent. Leaves linear or narrowly elliptic to narrowly obovate, to 20 mm long and 4 mm wide, silky on both surfaces and with a silvery sheen. Inflorescence borne at the ends of short densely leafy side-shoots with white flowers to 15 mm wide. Flowering between October to January. Fruits are woody hairy fruit to 10 mm wide, persistent. Seeds are brown narrow ovoid seed 3 mm long and 0.8 mm wide, with a linear-striate surface pattern. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between January and December. Collect mature capsules, those that are turning brown, hard with non-open valves. Mature fruits can remain on the plant unopened for sometime. 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 90%. Seeds are non-dormant, viable seed should germinate readily.
