Carpobrotus acinaciformis: complete guide

Overview

Carpobrotus acinaciformis, commonly known as Red Hottentot Fig or Griffe de sorcière, is a striking succulent from the Aizoaceae family (ice plant family). This plant is native to South Africa, growing primarily in the Cape Province. The plant stands out for its fleshy, juicy leaves and brilliant magenta flowers that appear throughout summer.

Appearance & Bloom Cycle

The Red Hottentot Fig forms low mats of 10 to 30 cm height with a spread that can reach meters. The leaves are long, compressed, and saber-shaped, grayish-green in color with reddish tints. The large flowers (3 to 4 cm wide) are bright magenta to purple and appear from April to October under favorable conditions, especially May through June. The flowers open in the morning and close in the afternoon - typical for Carpobrotus species.

Ideal Location

This plant thrives in very sunny, dry locations. Plant it on rock gardens, steep slopes, roof gardens, or in containers on sunny terraces. The plant refuses to grow in shade and requires full sun for optimal flowering. Strong wind poses no disadvantage. Ideal for Mediterranean gardens and coastal gardens.

Soil Requirements

Carpobrotus acinaciformis demands sandy, well-draining soils. pH can be neutral to slightly alkaline (6.5 to 8.0). Heavy soils almost certainly lead to rot. Add abundant gravel, sharp sand, and some organic material. Potting soil for cacti and succulents is suitable. Fertilizer need not be added.

Watering

This succulent is extremely drought-tolerant. Water only during very dry periods and then sparingly. During the growing period (April through October) watering can be done once every two to three weeks in very dry conditions. In winter, do not water - the plant rests. Excessive moisture causes root rot.

Pruning

Pruning is not necessary. However, you can remove old, dead, or damaged branches to shape the plant. Broken leaves can be removed. The plant naturally grows low and compact.

Maintenance Calendar

February-March: Planting season for mild climates.

April-June: Peak flowering period; minimal maintenance needs.

July-October: Continuous flowering; water only during extreme drought.

November-January: Rest period; no water; no maintenance needed.

Winter Hardiness

Carpobrotus acinaciformis is hardy to approximately -5°C (USDA zone 10). In temperate climates, it grows best in containers that can be protected or brought indoors during winter. In milder coastal regions, it can grow in the ground. Protection from cold and moisture is essential in wetter zones.

Companion Plants

This succulent works well with other Mediterranean and dry garden plants. Combine with Echeveria, Sedum, Sempervivum, and other succulents. Plant with dry grasses such as Festuca and silver-leaved plants such as Senecio. Bees and insects readily visit the flowers.
