Propagation
Fresh seed should be sown in a well-drained media and the kept moist but not wet. Maintain a temperature of 18ş to 21ş C. (64ş to 75ş F) in an unheated glasshouse or open frame. Germination occurs within 3-weeks to 3-months depending on the species, then prick out and pot up.

Careful not to over water seedlings, as they are prone to damping off and larger plants are difficult to transplant. When removing seed from Banksia fruits it may be necessary to place the fruit in an oven for 60 minutes at a temperature of 120° C. to simulating the effect of a bushfire to opening the valves.

Note:
This species seeds will germinate in 22 to 35 days and it is will produce flowers from seed in 10 years.

General pruning information
When pruning reduce only the new growth as cutting old wood is likely to cause dieback. Limbs may be removed back to the collar.

Cultivation
Generally, Banksia species prefer a well drained, sandy soil that is tending acidic but many species from Western Australia grow on acidic top soils with alkaline subsoil. When the growing Western Australian species outside their native habitat technique of building a garden bed, of acidic soil above a layer of agricultural lime commonly produces better results particularly in raised garden beds or on slopes. During establishment, keep the soil moist but not wet and do not use fertiliser that contains phosphorus.

Botanic information
Leaf: The dark green linear leaves are up to 400 mm (16 in) long by 20 mm (ľ in)wide and have numerous triangular pointed lobes that are divided to the mid-rib (dentate). The underside is covered in greyish tomentose and the leaves have a stiff leathery texture.

Flower: The golden yellow tubulate flowers have straight pubescent perianth segments that are up to 27 mm (1? in) long and a pistil to 35 mm (1? in)long. They are arranged in a broadly ovoid spike that is 110 mm (4? in) tall by 75 mm (3 in) wide and appear on a short lateral branchlets from, autumn to early winter and the spent flowers are persistent on the plant.

Fruit: There are up to 15-curved obliquely-obovate greyish follicles that are up to 65 mm (2˝ in)long by 50 mm (2 in) high and 35 mm (1? in) wide. They arranged in a spike that is persistent of the plant. The follicles open after fire and release broadly obovate seeds that are to 12 mm (˝ in) long by 17 mm (? in) wide and have a curved notched wing up to 50 mm (2 in) wide.

Note:
Generally the fruit consists of a few very large follicles that are mottled and covered in fine greyish tomentose. The persistent fruit is squad and appears like a propeller, hence the common name.
