Banksia sceptrum is one of the most striking yellow flowered banksias of all. Its tall bright yellow spikes are terminal and well displayed. Flowering is in summer, mainly December and January.
Grows naturally as a shrub to 6 metres in deep yellow or pale red sand in tall shrub land and commonly found on dunes. In exposed areas it is often found smaller.
Endemic to the mid west sandplains around Geraldton in Western Australia.
Prefers a light well-drained soil in an open sunny position, avoid waterlogged soils. Drought tolerant but frost tender.
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-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 were discarded.
