Banksia spinulosa was first collected by John White (surgeon of the First Fleet) in 1792. It would have been native to the site of the first white settlement in Sydney Harbour. B. spinulosa is pollinated by many species of birds and mammals. It has a lignotuber which means it can re-sprout from ground level after the above-ground parts are destroyed by a bushfire.

It is a very ornamental species and several varieties and natural hybrids are recognised. Grows successfully in sandstone soils as well as rocky clays and loams. Plants are resistant to phytophthora and prefer moist, well drained soils.

Grows successfully from seeds or cuttings.

Not known to be weedy.

Widely available in nurseries.
