GREVILLEA bipinnatifida

A very attractive prostrate shrub with a 2 metre spread that produces large pendant red-orange flowers 20 cm long. Flowering occurs during most of the year but occur more profusely during late autumn through to mid-summer putting on a magnificent display.
The vigorous growth habit of forming a dense trailing mat makes a great ground covering shrub. Grows equally as well if tubs and containers.

This Grevillea is parent to several commercially grown Grevillea's including Grevillea Robyn Gordon, Grevlliea Superb and Mason's Hybrid often referred to as Grevillea Ned Kelly. 

Prefers a light to medium well-drained soil in an open sunny position. Drought and frost resistant.

Occurs naturally in the South-West Province of Western Australia.

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 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.

1. Soak seed overnight in warm water.
2. Sow seed on a porous seed raising mix and cover lightly. Do not bury seed deeply.
3. Place in a warm shaded or semi shaded position to avoid dying out.
4. 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. 
5. 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.
