Holly Leaf Grevillea
Characteristics: Shrub 2-3 m spread 2 m
Seed per packet: 5
This hard to find Grevillea in another stunning flowering plant from this genus. Ornamental grey leaved shrub with greyish green oak like leaves.
Bright red or yellow flowers occurring in pendant clusters and appear during autumn and winter.
Endemic to Northern Australia.
Prefers a well-drained soil in an open sunny position, drought and frost tender.
Although seed can be sown most of the year in 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.
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.
