The plant family Ericaceae (heaths and heathers) is widespread in many parts of the globe, particularly Europe and South Africa. It contains a number of widely cultivated plants such as Erica, Rhododendron and Pieris.
Like most of Australia’s members of the Ericaceae, Leucopogon belongs to the subfamily Epacridoideae, which was formerly classified as a separate family, the Epacridaceae. Leucopogon consists of about 160 species, mostly Australian but some are also found in New Zealand and in islands to the north of Australia. They occur in a variety of habitats from sub-alpine areas to coastal heaths.
This species was previously known as Leucopogon lanceolatus but this prior name was found to
be invalid according to naming conventions.
L.affinis is a medium to large bushy shrub, usually 2 to 3 metres high but occasionally higher. The lance-shaped leaves are about 2-8 cm long with several distinct veins. Flowering is usually in spring and the small, white flowers are about 4 mm long, occurring in racemes of up to 10 or more flowers. As is typical of the genus, the flowers have hairy lobes.
Few leucopogons are seen in cultivation, mainly due to difficulties in propagation and those that have been cultivated have proven to be difficult to maintain. L.affinis is more successful in cultivation than most other species but even it is rarely seen in gardens. It seems to prefer a moist, well drained situation in semi shade.
Propagation of L.affinis is difficult. Germination of seed is usually slow and unreliable using conventional methods. Cuttings are also unreliable and may produce a limited success rate. Cuttings of firm current season’s growth are likely to give the best results and use of a root-promoting hormone is advisable.
