Characteristics: Tree to 8 m
Seeds per packet: 5
A large shrub or small tree with rough grey bark and cylindrical greenish-yellow, ageing to bright yellow flower heads up to 40 cm long by 10 cm wide.
The large leaves are divided into triangular segments, the young growth may be bright red.
The cones that follow the flowers are large and dense are often used in wood turning because of their size.
Endemic to Western Australia where the species is found in the south west corner of the State.
Prefers a light to medium well-drained soil in an open sunny position. Drought resistant but frost tender. Avoid waterlogged soils.
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
Pre-treatment of smoke: Not considered critical to germination of this species and germination will generally occur without it.
However many members of the Proteaceae family 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 of the Proteaceae family.
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.
