GREVILLEA aurea
Golden Grevillea
Family: Proteaceae
Subfamily: Grevilleoideae
Characteristics: Tall shrub 2-6 m spread 1-2 m
Seed per packet: 5
Attractive blue-green foliage 7-16cm long, oblong-dentate with 4-12 toothed lobes per side.
Flowers hanging in pendant clusters appear mainly in autumn and winter but plants in cultivation may have some flowers for most of the year. Flower buds are coppery brown, opening to yellow-orange flowers.
As with most grevillea the flowers attract nectar seeking birds. Endemic to the Northern Territory.
Prefers well drained soils in full sun but is frost tender and not suited to cold climates.
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
Larger seed of Grevellia species can be carefully nicked with a sharp knife to expose the embryo slightly prior to sowing, this can assist with the uptake of moisture and can speed germination.
- Soak seed overnight in warm water.
- Sow seed on a porous seed raising mix and cover lightly. Do not bury seed deeply.
- Place in a warm shaded or semi shaded position to avoid dying out.
- The growing medium should be well draining but should remain damp between watering. Keep moist but not too wet as the seed may rot. Do not let the growing mix completely dry out.
- Germination should occur in 21-60 days depending on the temperature and conditions.
Pre-treatment of smoke: Not considered critical for this species but may be beneficial.
Many members of the Proteaceae 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.
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.
