Banksia Paludosa

Banksia paludosa, commonly known as the marsh or swamp banksia, is a species of shrub in the plant genus Banksia. It is endemic to New South Wales, where it is found between Sydney and Batemans Bay, with an isolate population further south around Eden. Two subspecies are recognised, the nominate of which is a spreading shrub to 1.5 m (5 ft) in height, and subsp. astrolux is a taller shrub to 5 m (16 ft) high found only in Nattai National Park.

Native mammals, such as the Brown Antechinus and Sugar Glider, are important pollinators of Banksia paludosa. Several species of honeyeaters visit the flower spikes, as do ants and the European honeybee. The response to bushfire depends on the subspecies; subspecies paludosa regenerates from underground lignotubers, while plants of subspecies astrolux are killed by fire and regenerate from large stores of seed which have been held in cones in the plant canopy. Banksia paludosa is sometimes seen in cultivation, with dwarf forms being registered and sold.
