Historic Botanical Significance:

The Coastal Banksia holds special significance in botanical history.

As one of the original four Banksia species identified and collected by the legendary Sir Joseph Banks during his 1770 voyage along the Australian coast, this tree represents Australian botanical heritage and scientific exploration.

Its inclusion in Linnaeus's original genus description establishes its importance in plant taxonomy.

Wide Natural Distribution:

Banksia integrifolia, commonly known as the coast banksia, is one of the most widely distributed Banksia species.

It occurs between Victoria and Central Queensland in a broad range of habitats, from coastal dunes to mountains. 

his extensive natural range reflects the tree's exceptional adaptability and hardiness across diverse Australian conditions.

Distinctive Silvery Leaf Undersides:

Its leaves have dark green upper surfaces and white undersides, a contrast that can be striking on windy days. 

This distinctive two-tone foliage creates visual interest and textural appeal, particularly noticeable when breezes reveal the silvery undersides.

The contrast between dark green and silver creates an attractive ornamental characteristic.

This Australian Native tree has long green leaves with a silvery underside that produces pale yellow cylindrical flowers from January to June. 

The distinctive pale yellow flower spikes appear throughout summer and into winter, creating ornamental displays while attracting native birds and bees.

The extended flowering period ensures prolonged seasonal interest.

Bird & Bee-Attracting Properties:

The abundant flowers make the Coastal Banksia highly attractive to native Australian birds and bees.

The nectar-rich flowers provide essential food sources for local wildlife, supporting ecosystems while bringing natural bird life and pollinator activity to your garden.

Size & Growth Characteristics:

It is highly variable in form but is most often encountered as a tree up to 25 metres in height. 

Growth size typically reaches 5-20m h x 4m w, though specimens can occasionally exceed these dimensions.

The naturally developing form is attractive without requiring extensive pruning or shaping.

Exceptional Hardiness & Wind Tolerance:
