Christmasbush

Christmasbush (Ceratopetalum gummiferum) is a small tree or large shrub in the family Cunoniaceae, native to New South Wales, Australia. It is perhaps the best-known plant associated with the Australian Christmas season, as its small white flowers are replaced in summer by persistent, enlarged, bright red sepals that give the plant a highly ornamental appearance around the Christmas period. The species grows naturally in dry to wet sclerophyll forests and woodlands on sandstone and related soils along the coast and tablelands of New South Wales. It is a popular cut flower and is harvested commercially and from private gardens throughout the state. The genus Ceratopetalum contains several species, all endemic to Australia and New Guinea. Christmasbush is also widely cultivated in gardens for its ornamental value. It plays a modest ecological role in woodland communities, supporting insects and birds. The species tolerates a range of soil conditions but generally performs best in well-drained, acidic soils. Its drought tolerance once established makes it suitable for low-water gardens. Harvesting of branches for the cut flower industry and garden collection has not significantly threatened wild populations, which remain widespread throughout suitable habitat in New South Wales.
