Leucadendron R.Br.

Gold Tips

Greek leukos — white, dendron — tree, referring to the visual impression given by L. argenteum.

Evergreen trees and shrubs to 10 m tall, but mostly much smaller. Leaves alternate, entire, leathery, those below the flower heads often brightly coloured and petal-like. Flower clusters axillary and terminal, the sexes on separate plants. Male flowers loose, spherical, fluffy, not cone-like. Female flowers cone-like, formed of overlapping bracts. Fruit a broad nut.

Grown for the impressive flower heads with leafy bracts at the base of the flowers, mostly coloured in winter and spring in shades of yellow or grey and tinged with pink; they make exceptional cut flowers.

The variability of species in the trade, variability of male and female plants, and technical difficulty of characters make an identification key impractical.

80 species from S Africa.

Seed, as soon as produced and most species also from hardwood tip cuttings.

Male and female flower clusters occur on separate plants; fruit hidden within the bracts of the mature female head.

Mt Lofty Bot. Garden, Adelaide, had 38 taxa in 1991.
