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:
The seeds from this species require no pre-treatment and germinate in 21 to 42 days. When sowing at the wing point upwards and keep warm and moist but not wet.

Botanic information
Leaf: The dark green linear leaves up to 12 mm (˝ in) long by 1 mm wide and have revolute margins. The upper surface is glabrous and the underside is woolly and the apex is obtuse. They are arranged alternately pointing forward and densely along the branchlets.

Flower: The golden-yellow perianth segments are up to 10 mm (? in) long and hirsute on the outside and the protruding straight or curved bright yellow pistil is up to 25 mm (1 in) long. The flowers are arranged densely in a terminal or lateral squat-cylindrical spike that is up to 25 mm (1 in) long by 50mm (2 in) wide. They appear from summer to early winter and sporadically throughout the year. The old flowers soon fall from the plant.

Note:
Generally Banksia flower spikes are composed of hundreds of small individual tubular flowers (florets) that are densely arranged around a single cylindrical axis.

Fruit: The numerous elliptical follicles are up to 17 mm (? in)long by 3 mm (? in) high and 7 mm (Ľ in) wide and are smooth and hirsute. They are arranged in a golf-ball size spherical woody cluster that persists on the plant and opens after fire to release smooth cuneate seeds that are up to 20 mm (ľ in) long. The smooth seed body is cuneate to oblong, up to 11 mm (? in) long by 4 mm (? in) wide and has a wing to 12 mm (˝ in) wide.

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 an 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.
