coast banksia

Coast banksia (Banksia integrifolia) is a highly variable evergreen tree or large shrub in the family Proteaceae, native to the eastern coast of Australia from Queensland south to Victoria. It grows on coastal dunes, heathland, dry sclerophyll forest, and sandy soils adjacent to the sea, tolerating salt spray, poor soils, and periodic drought. One of the most widely distributed of all banksias, it bears leathery, elongated leaves that are dark green above and white or silver beneath, an adaptation reducing water loss in exposed coastal conditions. Cylindrical yellow flower spikes are produced almost year-round, providing nectar for honeyeaters, lorikeets, and invertebrates. Fruits are woody follicles containing seeds that can be released by fire or natural senescence. Coast banksia is assessed as Least Concern by the IUCN. It is among the most commonly cultivated banksias in Australian horticulture, widely used in coastal revegetation and streetscaping. Its dense growth form provides shelter for small fauna. Populations are generally stable, though localised pressures include urban expansion along the eastern coastal strip and invasion by introduced plants.
