A slender tree or shrub with red and yellow flowers occurs in pendant clusters from May to August in their native range with sporadic flowering throughout the year.
Typically grows with an erect stem and an open-textured crown. Leaves are pinnate with oblanceolate leaflets.
Endemic to northern Australia.
Prefers light to medium well-drained soil in a protected sunny position, drought, and frost tender.
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 grevillea 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: Research has shown although not critical smoke treatment may assist with the germination of this grevillea.
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.
