Red List of South African Plants: Near Threatened

A population reduction of nearly 30% is estimated based on a decline of 27% of known subpopulations and 30% habitat loss to crop cultivation and alien pine and hakea invasion in the past 60 years (generation length 20 years). Climate change models predict a population reduction of up to 50% by 2025 (Bomhard et al. 2005), but this is considered an unlikely, worst-case scenario.

The best time to sow is usually autumn or spring when the temperature range is between 16-22°C, and there is a difference of day and night temperatures of around 12°C.
If your summers are hot and dry and winter is moderate and wet, autumn is the best time to sow.
In colder climates with less harsh summers, it is usually better to sow in spring.

  1. The growing medium should be well draining but should remain damp between watering.
  2. Sow the seed equal to its side deep. Vermiculite is an excellent medium to cover the surface as it helps retain moisture and controls the temperature. 
  3. Keep moist but not too wet, as the seed may rot. Do not let the growing mix completely dry out. 
  4. Germination should occur in 30-60 days, depending on the temperature and conditions. 

Pre-treatment of smoke is recommended:
Members of the Proteaceae 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 by soaking the seed overnight or applying it to the surface after sowing; both provide good results. Smoke treatments are available by clicking here.

*Please note:

  • Please do not be too hasty to discard seeds that do not germinate; seeds will often lay dormant until the conditions are similar to their natural germination requirements.
  • As with all seeds, they must have adequate water to keep them moist but not too wet.
  • These growth notes are provided as guidance only and do not guarantee successful germination.
