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.

Conservation code:
Priority 1: Poorly-known species
Species that are known from one or a few locations (generally five or less) which are potentially at risk. All occurrences are either: very small; or on lands not managed for conservation, e.g. agricultural or pastoral lands, urban areas, road and rail reserves, gravel reserves and active mineral leases; or otherwise under threat of habitat destruction or degradation. Species may be included if they are comparatively well known from one or more locations but do not meet adequacy of survey requirements and appear to be under immediate threat from known threatening processes. Such species are in urgent need of further survey.

Prefers deep well-drained sandy soil in an open sunny position. Avoid waterlogged soils. Drought and frost resistant.

The best time to sow Banksia seeds is autumn or spring. Sow in contains and transplant when they are big enough to handle.
The growing medium should be well draining but should remain damp between watering. Banksia dislikes wet roots, so don't overwater them, or they will rot.
Sow the seed flat around 5mm deep. Vermiculite is an excellent medium to cover the surface as it helps retain moisture and controls the temperature.  
Germination should occur in 14-40 days at 20-25°C

Pre-germination of seeds by sowing into a closed container containing moist vermiculite or similar material is also helpful for 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 the pre-treatment of smoke.
Smoke treatments are simple and can be undertaken by soaking the seed overnight or applying it to the surface after sowing; both provide good results.  Smoke treatments are available by clicking here.

*Please note:

  • Please do not be too hasty to discard seeds that do not germinate; seeds will often lay dormant until the conditions are similar to their natural germination requirements.
  • As with all seeds, they must have adequate water to germinate, keep them moist but not too wet.
  • These growth notes are provided as guidance only and do not guarantee successful germination.
  • The customer should do their due diligence that they are suited to their region.
