Characteristics: Small spreading or erect shrub 30 cm - 1.5 m
Seed per packet: 5
A small spreading or erect shrub with a rounded growth habit that varies in size depending on the conditions of its location. Typically grows to around 1.5 m tall although it can attain a height of only 30 cm in exposed or harsh conditions.
Blue green holly-like foliage and small pendent spider like cream-yellow flowers from early winter to mid spring. An attractive Grevillea and can be used as a low hedge.
Endemic to the wheatbelt region east of Perth Western Australia.
Grows in a range of well-drained sandy or gravelly soil in a sunny position. Drought and frost tolerant.
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 is recommended for this grevillea.
Pre-treatment of smoke:
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.
