Silver banksia
Banksia marginata, family Proteaceae
A variable Australian shrub or tree with silvery leaves and yellow flower spikes
Silver banksia is a highly adaptable plant found across southeastern Australia, from South Australia through New South Wales, Tasmania and Bass Strait islands. It ranges from low coastal shrubs to tall forest trees, bearing narrow green leaves with white undersides and cylindrical yellow flower spikes that attract birds and bees.
- Leaves have white undersides that create a silvery appearance
- Flower spikes contain up to 1,000 individual flowers
- Some populations regenerate only after bushfire, others resprout
- Dwarf garden forms are commercially available
- Reported as tall as 30 metres in rare cases
What does Silver banksia look like?
Silver banksia varies greatly in size, from compact shrubs just 20 cm tall on coastal heaths to trees up to 12 metres high in forests. Its narrow leaves are dull green above and strikingly white underneath, giving the foliage a silvery sheen. Cylindrical yellow flower spikes appear from late summer to early winter, each made of hundreds of tiny flowers packed around a woody core.
Where does Silver banksia come from?
First collected near Sydney in 1793, it was named by Spanish botanist Antonio José Cavanilles in 1800. Early explorers described similar plants under different names, but these were later merged into one species by George Bentham in 1870. The name 'marginata' refers to the leaf margins that curl under, revealing the pale underside.
When and how Silver banksia blooms
It grows in many habitats, eucalypt forests, scrub, heathland and moorland, across southeastern Australia. Flowering occurs mainly from February to June in mainland states, though timing shifts in cooler areas like the Gibraltar Range. After blooming, woody seed pods develop, which may open spontaneously or only after fire, depending on the population.
How Silver banksia is used
Though occasionally used for timber, silver banksia is now mostly grown in gardens, especially dwarf forms bred for small spaces. Its nectar-rich flowers feed honeyeaters and bees. In the wild, it plays a key ecological role, with some populations relying on fire to release seeds while others resprout from underground structures.
Kinds of Silver banksia
This species shows extreme variation: tiny shrubs in Tasmanian coastal heaths, mid-sized bushes in national parks, and unusually tall trees over 15 metres in parts of Victoria and Tasmania. Despite this diversity, no formal subspecies are recognised, though experts note more study is needed.
What Silver banksia means
Known as warock in Jardwadjali (western Victoria), pitpauwe in Kaurna (Adelaide Plains), and tangan in Macquarie Harbour (Tasmania), it has long been part of Indigenous landscapes. Captain Cook noted a similar plant in 1777. Today it is valued in horticulture and conservation for its resilience and wildlife value.

What does it look like?
It ranges from a low shrub to a tall tree, with narrow green leaves that are white underneath and cylindrical yellow flower spikes in late summer to early winter.
How does it respond to fire?
Some populations die in fire and regrow from canopy-stored seeds; others survive by resprouting from underground lignotubers or roots.
Is it used in gardens?
Yes, especially compact or dwarf forms, which are propagated and sold for home gardens.
What animals visit its flowers?
Honeyeaters, native bees and European honeybees forage at its nectar-rich flower spikes.
