BANKSIA serratuloides syn Dryandra serratuloides

Banksia serratuloides typically grow to around 50 cm in height and produce attractive yellow and pink flowers head from July to September. Foliage consists of dark-green serrated leaves.

Occurs naturally in the regions of the Avon Wheatbelt, Jarrah Forest, and the Swan Coastal Plains of Western Australia. 
Occurring over only 9 small populations in Western Australia Banksia serratuloides is classified as Rare and Threatened.

Previously known as Dryandra serratuloides. Dryandra was considered a separate genus named Dryandra until early 2007 when it was merged into Banksia.

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

Grow notes:

Although seed can be sown most of the year in many parts of 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

1. The growing medium should be well-draining but should remain damp between watering.
2. 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. 
3. Keep moist but not too wet as the seed may rot. Do not let the growing mix completely dry out. 
4. Germination should occur in 21-60 days depending on the temperature and conditions. 

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 are 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 have been discarded.
