Banksia integrifolia Coast (Coastal) Banksia

Genus: Banksia. 

species: integrifolia.


Common Name: Coast (Coastal) Banksia.

Etymology:  Banksia: After Sir Joseph Banks (1743–1820) patron of natural sciences who also sailed around the world with Captain Cook 1768-71.  integrifolia: entire, undivided (leaves).

Origin: Coastal Victoria to central Queensland Australia.

Description:  Medium sized tree up to 25 metres in height, but in sheltered locations it can reach 35 metres. In more exposed areas it may grow as a small, gnarled  and twisted tree, reaching no more than about 5 metres, and in highly exposed coastal headlands, it may even be reduced to a small shrub.

Foliage: Dark green above & silvery-white hairs below with prominent midrib. Leaves are 4-20 cm long & 6-35 mm wide, oblong to narrow lanceolate or wedge shaped with a short stalk. 

Bark: Hard, rough, light grey, sometimes fissured with granular appearance.      

Flowers: Pale-yellow, tubular, 22-25 mm long with wiry, straight, protruding styles, grouped in cylindrical terminal upright spikes, 5-15 cm long & 5- 8 cm diameter. Flowers mainly in Summer, Autumn & early winter.   

Fruit: Grey oblong to cylindrical cones, 7-15 cm long & 7-8 cm diameter with numerous brown protruding follicles, 8-17 mm long, usually containing 2 black winged ovate seeds, released at maturity.

Growth Requirements: Well drained sandy-sandy loam soil in sunny to part-shade position. Plant will not tolerate waterlogged soil.

Uses: Coastal, poor & sandy soils, Australian native gardens, bird attracting.

Maintenance: Little maintenance is required as plant is quite hardy. Regular deep watering will help establish plant in the first 12 months and a low phosphorus fertilizer (use Australian Native) can be used very sparingly.

Propagation: Is easy from seed. A common way to release seed is to place the ‘cone’ in an oven at 120°­140° C for about an hour. The follicles then open and the seeds can be removed with tweezers. Seeds should be sown in a very freely draining seed-raising mix which should not be allowed to dry out. As Banksia seedlings are prone to fungal attack, it is better to sterilise the seed-raising mix before planting. If this is not practical, very clean ingredients should be used. Propagation from cutting is the only reliable way to maintain a selected form, but success can often be difficult.
