Banksia marginata

Banksia marginata.
Banksia marginata, the silver banksia, is a species of tree or woody shrub found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including Eucalyptus forest, scrub, heathland and moorland. B. marginata varies widely in habit, ranging from a small shrub, 20 cm (7.9 in) high, to a large tree, 12 m (40 ft) tall. Its narrow leaves are linear. Its yellow flower spikes appear in late summer, eventually fading to brown and then grey and developing woody follicles bearing the winged seeds. Many species of bird, in particular honeyeaters, forage at the flower spikes, as do native and European honeybees. Although the silver banksia has been used for timber, it is most commonly seen as a garden plant, with dwarf forms being commercially propagated and sold.
