Family: Proteaceae
Characteristics: Groundcovering shrub to 30 cm spread 1 m
Seed per packet: 5
Sold by seed count
Protea belongs to the ancient plant family Proteaceae, which split into two subfamilies, Proteoideae and Grevilleoideae, before the separation of the Gondwanaland continent around 140 million years ago.
Protea coronata is an erect shrub that is usually around 2-3 m tall but occasionally taller. Stems have dense, long hairs, green leaves turning purplish around the flower head, and flowers are bright green with a white centre. Flowering occurs between April and September.
Prefers a rich, sandy, well-drained soil in an open sunny position, drought-resistant but frost tender.
Occurs naturally in the Western Cape of South Africa.
Near Threatened in the wild.
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.
- The growing medium should be well draining but should remain damp between watering.
- 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.
- Keep moist but not too wet, as the seed may rot. Do not let the growing mix completely dry out.
- 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 germinate; keep them moist but not too wet.
- These growth notes are provided as guidance only and do not guarantee successful germination.
- The customer should do their due diligence that they are suited to their region.
