A recently discovered Banksia was found only in a limited range around Mount Magnet in Western Australia. Found in the year 2000 it was only formally named in 2002. It was not until 2006 before the first flowering was observed.
A medium-sized shrub with attractive greenish-yellow flowers in bud changing to lemon yellow when mature that occur generally from July to October.
Occurs naturally over a limited area of arid lands and has the potential to become an ideal species for drier climates.
Priority 1: Poorly-known species
Prefers deep well-drained sandy soil in an open sunny position. Avoid waterlogged soils. Drought and frost resistant.
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.
