Characteristics: Shrub or small tree 3 to 8 metres
Seeds per packet: 5
An attractive shrub or small tree with an orange-brown corky barked trunk the Wallum Banksia can reach a height of 8 metres but typically forms a habit of a robust shrub with large stiff serrated foliage.
Upright pale cream yellow to bright yellow-orange flowers 85 mm wide and 100 - 150 mm tall occur during Autumn and early Winter.
A lignotuberous species of Banksia (the ability to re-sprout from the base of the truck after bush fires or being damaged)
Banksia aemula is one of the first banksias to be transported back to England by the early explorers, closely resembles Banksia serrata.
Occurs naturally in the swampy heathland of the coastal areas of New South Wales and southern Queensland.
Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn in temperate climates, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C
Pre-germination of seed by sowing into a closed container containing moist vermiculite or a 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: Not considered critical to germination of this species and germination will generally occur without it.
However many members of the Proteaceae family are responsive to pre-treatment of smoke. Although germination will often occur without smoke treatment it has proved to be beneficial in reducing the number of days to germination and increasing germination rates in many species of the Proteaceae family.
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.
General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they are discarded.
