Propagation
Fresh seed should be sown in a well-drained media and the kept moist but not wet. Maintain a temperature of 18º to 21º C. (64º to 75º 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.  

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 blue green linear (needle-like) leaves are up to 120 mm (4¾ in) long by 3 mm (⅛ in) wide with an obtuse apex and revolute margins. The upper surface is pubescent when young, becoming glabrous and the underside are woolly. They are arranged alternately along the whitish woody branchlets.

Flower: The tubulate flowers have perianth segments that are up to 45 mm (1¾ in) long and a pistil to 48 mm (2in) long. They are arranged in a upright cylindrical spike that is 50 mm to 70 mm (2⅔ in) tall by 90 mm (3½ in) wide and appear on short lateral branchlets from 2-year old wood from autumn to winter. The musky scented flowers vary in colour from rusty brown to yellow-orange or golden-brown and persist on the plant and wrapping around the developing follicles.

Fruit: The smooth woody densely hirsute elliptical follicles are up to 35 mm (1⅜ in) long by 18 mm (⅞ in) high and wide. They are  embedded in a spike that is persistent on the plant and releases the seeds after fire. The obovate seeds have a cuneate body up to 18 mm (⅞ in) long by 9 mm (⅜ in) wide and a wing up to 33 mm (1¼ in) wide.
