CHEIRANTHERA preissiana

Although seed can be sown most of the year in many parts of Australia seed is generally best sown in spring or autumn, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C for this species.

1. Sow seed on a porous seed raising mix and cover lightly. Do not bury seed deeply.
2. Place in a warm shaded or semi shaded position to avoid dying out.
3. The growing medium should be well draining but should remain damp between watering. Keep moist but not too wet. Do not let the growing mix completely dry out.
4. Germination should occur in 21-42 days depending on the temperature and conditions. 

Pre-treatment of smoke: Not considered critical for this species but some research has shown it may be beneficial.
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.
