Seed is usually best sown in spring or autumn in temperate climates, avoiding the coldest and hottest months of the year. The optimum germination temperature for germination of this genus is around 18-22°C
Pre-treatment of smoke is recommended for this species.
Research has shown that many members of this genus are responsive to the pre-treatment of smoke. Although germination may occur without smoke treatment it has proved to be beneficial in reducing the number of days to germination and increasing germination rates of this 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.
