Banksias were named after Sir Joseph Banks (1743-1820 ), who, in 1770, was the first European to collect specimens of these plants. The plant has no lignotuber and is regenerated from seed. In many species, the resulting structure is a massive woody structure commonly called a cone. Test your life expectancy with the Lifespan Calculator from Northwestern Mutual. Types: Scarlet banksia, golden banksia, rickrack banksia, red banksia, Ashby’s banksia, Hooker’s banksia. Leaves are green above and silvery grey below. Other associated fauna include the larvae of moths (such as the Dryandra Moth) and weevils, which burrow into the "cones" to eat the seeds and pupate in the follicles; and birds such as cockatoos, who break off the "cones" to eat both the seeds and the insect larvae. Woodturners throughout the world value Banksia pods for making ornamental objects. Occasionally, multiple flower spikes can form. Growing banksia is easy as long as you provide well-drained soil, full sunlight and excellent air circulation. If fertilised, only slow-release, low-phosphorus fertilizer should be used, as the proteoid roots may be damaged by high nutrient levels in the soil. Banksias are grown outside in field plantations, bush picking is now actively discouraged. The leaves are 25cm to 45 cm long and up to 10cm wide with deep triangular lobes. 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. This can be most spectacular in B. prionotes (acorn banksia) and related species, as the white inflorescence in bud becomes a brilliant orange. Generally slower growing than ever-popular eucalypts and acacias, and comfortingly long-lived, they maintain a more modest size than many of the speedy growers. Banksia ericifolia L.f. subsp.
