A spreading shrub that produces bright yellow flower clusters may be up to 80 mm in diameter and occur at the ends of the branches in spring. Dark brown bracts which occur at the base of the flower heads give them a very attractive appearance.

The foliage consists of stiff leaves about 100mm long with toothed margins, the new growth is a bronze colour and adds to the attraction of the plant.

Dryandra occurs naturally only in Western Australia.

Note: Formally known as Dryandra quercifolia.
Dryandra was considered a separate genus until early 2007 when it was merged into Banksia.

Prefers a light to medium soil in an open sunny position, drought resistant but frost tender.

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-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: 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 are discarded.
