Sandhill Spider Flower
Characteristics: Shrub 1.5-5 m spread 4 m
Seed per packet: 10
The Sandhill Spider Flower is a rounded shrub with long narrow leaves 10-25cm in length.
Large creamy white flowers up to 15cm long occur at the ends of the branches and cover the shrub in good seasons.
Flowers can occur at most times of the year but the best show time is winter and spring.
This handsome shrub is well suited to dry areas where it would make an excellent hedge or screen.
Endemic to the arid regions of Australia.
Prefers sandy well-drained soil in an open sunny position, drought and frost resistant. Dislikes humid areas and excessively wet climates.
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.
