ISOPOGON dubius - Pincushion Coneflower 2g

Isopogons are related to Grevilleas and Banksias.
A compact shrub with rose-pink pincushion-like flattened flowers occurs in spring followed by rounded nutlets. Attracts birds.
Typically with an erect and branching stem with a closely textured crown with bluish-green deeply divided prickly leaves.

Native to the South-West Province of Western Australia.

Prefers light to medium well-drained soil in a protected sunny potion, drought and frost resistant.

Grow notes:

Seed is usually best sown in spring or autumn, 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.

1. Sow seed on the surface of a porous seed-raising mix. The seed will lodge in the pores of the mix once watered.
2. Sprinkle a light covering of the seed-raising mix over the seed.
3. Water with a 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, and 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.
