Banksia sceptrum, the Sceptre Banksia, occurs in Western Australia near the central west coast from Geraldton north through Kalbarri to Hamelin Pool. It extends inland almost to Mullewa.

In nature, it grows in deep yellow or pale red sand in tall shrubland, commonly on dunes, being found as a shrub to 6 metres (20 ft) high, though often smaller in exposed areas. It is killed by fire and regenerates by seed. Follicles open with fire. Banksia sceptrum is one of the most striking yellow-flowered banksias of all. Its tall bright yellow spikes are terminal and well displayed. Flowering is in summer, mainly December and January, though occasional flowers are rarely seen at other times.

Ecology

An assessment of the potential impact of climate change on this species found that its range is unlikely to contract and may actually grow, depending on how effectively it migrates into newly habitable areas.[1]

Cultivation

It is principally used in the cut flower industry, with the immature spikes being commonly sold in florists around Australia. It is occasionally grown in gardens, but requires a Mediterranean (dry summer climate) and good drainage as it is sensitive to dieback.

Seeds do not require any treatment, and take 26 to 47 days to germinate.[2]
