The Cut-leaf Banksia (Banksia praemorsa) is a wonderful looking banksia, even as a young shrub, when the floral spike has a more ball shaped appearance instead of the candle shape of the mature shrub. A great ornamental banksia, adaptable to a variety of well drained soils and climate zones, it is considered a medium size shrub, but has been known to grown up to 7 metres high and 3 metres wide.

The Cut-leaf Banksia have bright yellow or dark red-purple coloured flowers. The flower spikes grow from the ends of small lateral branches, with a flower spike that can be up to 27 cm long. The flower spikes are composed of hundreds of individual flowers growing out of a central woody spike.

This species can tolerate coastal exposure, winds, moderate frost and dry periods. A great plant to attract birds.


It appears that there may be one or a number of reasons why the flower spike is small and ball shape – may need to increase watering for short periods; it may be because it is a young bush (so just give it time); genetic diversity (occasionally a plant will have smaller blooms then others).


Many thanks to Ollie Sherlock from Australian Indigenous Plant Identification Facebook group, and others for identifying this plant. Also thanks to the members of Banksia lovers Facebook group including Angela N Ross Shepherd, Matthew Wisniewski and Kevkathy Collins for the additional input.
