Another threat to Banksia is the water mould Phytophthora cinnamomi, commonly known as "dieback". Woodturners throughout the world value Banksia pods for making ornamental objects. The flower spikes are conspicuous and contain between 100 and 6000 individual flowers. It produces spectacular red and white spikes of bottlebrush-shaped flower heads in spring and summer. [1] Banksia species that grow as shrubs are usually erect, but there are several species that are prostrate, with branches that grow on or below the soil. The Fishbone Banksia is a prostrate shrub. Most species do not grow well near the coast, notable exceptions being the southern Western Australian species B. speciosa, B. praemorsa and B. repens. Conferta is a dense shrub growing to around four metres tall. The remaining species usually survive bushfire, either by resprouting from a woody base known as a lignotuber or, more rarely, epicormic buds protected by thick bark. All you need to do is give that bunch of flowers the TLC they need to achieve their maximum longevity. Banksia is a genus of around 170 species in the plant family Proteaceae.These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. Austin Mast and Kevin Thiele published the official merging of Dryandra within Banksia in 2007, recalibrating the genus into subgenus Banksia and subgenus Spathulatae.[14]. Prickly Banksia is a bushy shrub with prickly serrated leaves. It has oval serrated leaves and lemon yellow flowers.

They are all woody evergreen plants, ranging in habit from prostrate shrubs to trees up to 30 metres tall. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of Dryandra (now Banksia) sessilis (Parrotbush) and D. (now Banksia) pellaeifolia. Southwest Western Australia is the main centre of biodiversity; over 90% of all Banksia species occur only there, from Exmouth in the north, south and east to beyond Esperance on the south coast. ericifolia. The flowers are arranged in flower spikes or capitate flower heads. Also on the south coast of Papa New Guinea and the Aru Islands tropical banksia species are grown. It has also been used to make keels for small boats. A number of Banksia cultivars have also been developed. As the flower spikes or heads age, the flower parts dry up and may turn shades of orange, tan or dark brown colour, before fading to grey over a period of years. Banksia plants are naturally adapted to the presence of regular bushfires in the Australian landscape. Brown ignored Knight's name, as did subsequent botanists. The fruit of Banksia is a woody follicle embedded in the axis of the inflorescence. They may need extra water during dry spells until established, which can take up to two years. Specimens of Banksia were first collected by Sir Joseph Banks and Dr Daniel Solander, naturalists on the Endeavour during Lieutenant (later Captain) James Cook's first voyage to the Pacific Ocean.

An Australian native plant named after 18th Century botanist, Sir Joseph Banks, Banksias are extremely diverse, ranging from prostrate shrubs to tall trees. All respond well to some form of pruning. Popular garden species include B. spinulosa, B. ericifolia, B. aemula (Wallum Banksia ), B. serrata (Saw Banksia), Banksia media (Southern Plains Banksia) and the cultivar Banksia 'Giant Candles'. The leaves are 25cm to 45 cm long and up to 10cm wide with deep triangular lobes.
