GREVILLEA eriostachya 5g
Yellow Flame Grevillea
Family: Proteaceae
Sub-family: Grevilleoideae
Characteristics: Shrub 1.5-2 m spread 2 m
Seed per packet: 5
Seed per gram: Approx. 28
Grevillea eriostachya is a spectacular ornamental bushy shrub to 2 metres with tall spectacular golden yellow flower stems emerging 30 cm above the foliage, usually in late winter and spring.
The foliage is grey-green, long, and fine with short dense hairs on the upper surface.
Endemic to a large area of Western Australia.
Prefers sandy well-drained soil in an open sunny position, drought, and frost-resistant. Dislikes humid areas and excessively wet climates.
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
Larger seeds 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.
Pre-treatment of smoke is recommended for this grevillea.
- Sow seed on a porous seed-raising mix and cover lightly. Do not bury the 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:
Many members of the Proteaceae are responsive to the 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 it 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 were discarded.
The best time to sow Grevillea seed is autumn or spring; avoid the hottest and coldest months of the year in cool temperate climates.
There are two main methods to assist germination.
- For larger seeds, the most usual pre-treatment method is to ‘nick’ or peel off the seed coat with a sharp blade(razer blade or shape knife to allow moisture to reach the embryo. This needs to be done with care to avoid damage to the embryo.
- For smaller seeds with thin walls, pour hot but not boiling water over the seed and allow them to soak for a day or two.
- 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 14 days too servel months depending on the temperature and conditions.
Pre-treatment of smoke: Not considered critical for this species but may be beneficial.

Please note:
- Please do not be too hasty to discard seeds that do not germinate; seeds will often lay dormant until the conditions are similar to their natural germination requirements.
- As with all seeds, they must have adequate water to germinate, keep them moist but not too wet.
- These growth notes are provided as guidance only and do not guarantee successful germination.
- The customer should do their due diligence that they are suited to their region.
