Banksia spinulosa is a variable species and not all authorities agree on the status of the various forms.
Four varieties are recognised in the Australian Plant Census:
Some intergrading between var. spinulosa and var. collina occurs where the ranges overlap and natural hybrids between B.spinulosa var. spinulosa and B.ericifolia subsp. ericifolia have been recorded in New South Wales.

The flower spikes of all forms are 75-100 mm wide, up to 450 mm long and yellow or orange in colour. This is one of a group of banksias with "hooked" styles projecting from the axis of the flower spike. In B.spinulosa these styles are often deep red or black in colour and this has given rise to the common name of "Hairpin Banksia", however, the styles may also be orange or yellow. The seeds are enclosed in follicles attached to a woody cone and are generally retained within the cone until burnt.
Despite the specific name, the foliage is not "spiny" in any sense that suggests that it is painful to touch.
Most forms of B.spinulosa have proven to be reliable in gardens in a wide range of districts. A number of select forms are becoming available, for example:

Another popular cultivar, Banksia "Giant Candles" is thought to be a hybrid with B.spinulosa as one of its parents.
Propagation from seed or cuttings is relatively easy. However, named cultivars must only be propagated from cuttings as they do not come true from seed.
