Sold by seed count.
A large shrub or small tree with rough grey bark and cylindrical greenish-yellow, maturing to bright yellow flower heads up to 40 cm long by 10 cm wide.
The large leaves are divided into triangular segments, and the young growth may be bright red.
The cones that follow the flowers are large and dense and are often used in woodturning because of their size.
Endemic to Western Australia where the species is found in the southwest corner of the State.
Prefers light to medium well-drained soil in an open sunny position. Drought-resistant. Avoid waterlogged soils.
Seed is best sown in spring or autumn in a temperate climate.
The growing medium should be well draining but should remain damp between watering.
Sow the seed 3-4mm deep. Vermiculite is a good medium to use to cover the surface as it helps retain moisture and controls the temperature.
Keep moist but not too wet as the seed will rot.
Germination should occur in 21-60 days at 18-22°C
Pre-germination of seed by sowing into a closed container containing moist vermiculite or similar material is also a useful method of germinating seeds, particularly for winter sowing when outdoor temperatures may be unsuitable. Germination usually occurs in 1-2 weeks using this method and when the root has reached about a centimetre or so in length, the seedling can be placed into a small pot of seed raising mix.

Pre-treatment of smoke: is not critical to the germination of this species. However many members of the Proteaceae family are responsive to pre-treatment of smoke
Smoke treatments are simple and can be undertaken either by soaking the seed overnight or by applying to the surface after sowing, both provide good results. Smoke treatments available by clicking here.
