History

A brief account

Tiger Jaws is one of the most playful-looking succulents, with thick, triangular leaves that look as though they have been edged with a row of little teeth. Native to the Eastern Cape of South Africa, it grows in nutrient-poor soils where morning dew and occasional rain are precious, so its unusual leaf structure helps collect and guide moisture toward the center of the rosette. That clever adaptation makes it both visually distinctive and highly suited to dry conditions. The genus Faucaria was first described in 1790, and the plant’s name reflects the open-jawed appearance of its paired leaves, which are soft rather than sharp but still give the plant a fierce, almost predatory look. Its compact rosette shape and bright yellow flowers have made it a favorite among succulent collectors who enjoy plants with both personality and ecological cleverness. In cultivation, Tiger Jaws prefers a very bright position, a gritty mineral mix, and careful watering. It does best when it is watered sparingly during active growth and left dry in the hottest or coldest seasons, as too much moisture can quickly cause rot. It can be propagated from seed or by dividing established clumps in spring, though it remains a slow-growing plant.

How to care for

Place Tiger Jaws according to its light needs: Bright direct sun. For watering, sparingly in spring and autumn; rest dry in summer and winter. For the potting medium, use very gritty mineral mix. Good drainage is essential: let surplus water escape freely and never leave the roots standing in a wet saucer. 10–28°C. Tolerates light frost when bone dry. Check the compost before watering instead of following a rigid calendar, since light, temperature, pot size and season all affect how quickly it dries. During slower growth, reduce watering and wait longer between drinks.

How to propagate

Grow from seed or divide established clumps in spring with care. Propagation is most reliable during the plant's active growing season, when warmth and good light help new roots establish. Start with clean tools and healthy material, and keep the new plant in conditions appropriate for the parent. Where a cutting or division creates a wound, allow the surface to dry before planting unless the method calls for immediate rooting in water or moist mix. Once roots form and fresh growth appears, gradually move the young Tiger Jaws into its normal watering routine; excess moisture is especially risky while the root system is still small.
