Carpobrotus edulis, commonly known as Hottentot Fig or Sour Fig, is a creeping succulent native to South Africa. Both the edible fruits and leaves are nutritious and have been traditionally used in South Africa, where the fruits are eaten fresh or made into jam, and the leaves are used for medicinal purposes. Seeds germinate readily over a wide temperature range, requiring light and consistent moisture for successful propagation.

What to expect
Tips
Surface sow seeds on moist, well-drained compost in spring (March to June). Place under glass or in a propagator. Seeds require light to germinate, so do not cover with soil. Maintain consistent moisture but avoid waterlogging, as the species is naturally adapted to well-drained sandy soils. Lower night temperatures (3-5°C below daytime) accelerate germination. Germination typically occurs within 7-10 days at 23°C. Once seedlings develop two true leaves, prick out into individual pots and grow in a greenhouse for the first winter. Transplant to permanent locations in late spring after the last frosts. This species germinates year-round and does not require stratification or pre-treatment. Ensure excellent drainage in the final growing medium, as the plant comes from coastal dunes.
