Small shrub with pink or mauve flowers conspicuously displayed on the ends of the branches during late winter and spring. The flower clusters are around 50mm in diameter and are followed by the spherical barrel-shaped seed pods.

Typical form is a slender stem and spreading branches with leaves that are divided with needle like segments 100 mm long.

Native to the central west coast to the Goldfields region of Western Australia.

Prefers a light to medium well-drained soil in an open sunny position, drought and frost resistant. 

Seed is usually best sown in spring or autumn, avoid 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 to be responsive to pre-treatment of smoke. Although germination may occur without smoke treatment it has proved 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 to the surface after sowing, both provide good results. Smoke treatments available by clicking here.

  1. Sow seed on surface of a porous seed raising mix. The seed will lodge in the the pores of the mix once watered.
  2. Sprinkle a light covering of the seed raising mix over the seed.
  3. Water with fine mist spray to avoid disturbance of the seed.
  4. Place in a warm shaded or semi shaded position to avoid dying out.
  5. Keep warm & moist, avoid drying out or waterlogging the growing mix.
  6. Germination generally occurs in around 21-42 days in the right conditions.

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.
