Ceratopetalum gummiferum, the New South Wales Christmas bush, is a tall shrub or small tree popular in
The specific name gummiferum alludes to the large amounts of gum that is discharged from cut bark.
Description
Plants initially grow as rounded shrubs but mature to pyramidical trees.[2] The leaves comprise three leaflets and are up to 8 cm long. The petioles are grooved on the upper side and are 10 to 20 mm long.[1] Small, white five-petalled flowers appear in sprays from October in the species' native range. As these die the sepals enlarge and become pink to red in colour, the display peaking at Christmas time in Australia.[2]
Taxonomy
Ceratopatalum gummiferum is one of nine species in the genus Ceratopetalum which occur in Australia and Papua New Guinea. The species was first formally described by English botanist James Edward Smith in 1793 in A Specimen of the Botany of New Holland[3]
Distribution and habitat
The species is endemic to New South Wales where it occurs to the east of the Great Dividing Range from Ulladulla in the south to Evans Head in the north.[1]
Cultivation
In cultivation, plants usually grow to no more than 6 metres in height.[2] Plants may be propagated from seed or cuttings, the latter method being preferred to maintain good colour forms.[4] Well-drained soil is required to avoid problems with dieback associated with root-rot fungus.[2]
