Faucaria tigrina – Tiger Jaws: An In-depth Look

Faucaria tigrina, commonly known as Tiger Jaws, is a distinctive succulent known for its unique appearance and easy care. It is characterized by its thick, triangular leaves that resemble an open animal jaw, complete with “teeth” along the edges. These teeth are actually soft, harmless spikes. The leaves are green to bluish-green with a slightly rough texture.

Native: This plant is native to South Africa, where it grows in arid regions, and thrives in rocky and sandy soils. Tiger Jaws belongs to the fig-marigold family, Aizoaceae, which contains 135 genera and about 1800 species, such as Lithops (Living Stones), Delosperma (Ice Plant), Aptenia cordifolia (Baby Sun Rose), Lampranthus spectabilis (Trailing Ice Plant) or Sesuvium portulacastrum (Sea Purslane).

Plant Type and Habit: It is a clumping perennial succulent that grows in rosettes.

Size: The plant typically reaches about 4 to 6 inches in height (10-15 cm) and spreads similarly around 6 inches (15 cm) wide.

Flowers: Tiger Jaws produces daisy-like, bright yellow flowers, 2 inches across (5 cm), that open in the afternoon sun and close in the evening or on cloudy days. The flowering season is mainly in the fall, though it can occasionally bloom into early winter. Following blooming, the plant produces small, capsule-like fruits that split open when dry, dispersing seeds.

Foliage: The foliage is the most striking feature, with thick, fleshy, triangular, gray-green leaves adorned with white or translucent “teeth” along the edges, giving it a fierce appearance.

Award: Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.

Hardiness: Tiger Jaws is hardy in USDA zones 9 to 11. It can tolerate temperatures down to about 25°F (-4°C) for short periods if kept dry.

Uses: It is primarily grown as an ornamental plant, ideal for rock gardens, succulent gardens, or as a potted houseplant. Its unique appearance makes it a popular choice for succulent collections.

Toxicity: There is no known toxicity to pets or humans, making it a safe indoor and outdoor plant.

Drought: Faucaria tigrina is extremely drought-tolerant, storing water in its leaves to survive long periods without rainfall.

Invasiveness: This succulent is not invasive; it grows slowly and is easily controlled in a garden setting.

Benefits: Its drought resistance and low maintenance make it an excellent choice for water-wise landscaping or for adding a structural element to rock gardens. It is also suitable for xeriscaping.

Tiger Jaws: How to Grow and Care

Growing and caring for Tiger Jaws can be straightforward with the right conditions. Here are essential tips to ensure a healthy plant:

Light: Tiger Jaws thrive in full sun to partial shade. In cooler climates, provide as much sunlight as possible. If grown indoors, place near a south-facing window to ensure it receives ample light.
In very hot climates, protect the plant from the intense midday sun to prevent scorching.

Soil: Use a well-draining sandy or gritty soil mix, ideally formulated for cacti and succulents. Good drainage is crucial to prevent root rot.

Water: Water the plant sparingly. Allow the soil to dry out completely between waterings. During the winter months, reduce watering even further to mimic its natural dormant period. Watch out for soft, mushy leaves which might indicate too much water.

Temperature: Tiger Jaws prefer warmer temperatures but can tolerate temperatures down to 25°F (-4°C) for short periods. They are not frost-tolerant, so bring them indoors if the temperature drops below freezing.

Humidity: This plant tolerates dry air but thrives in a moderate humidity environment.

Fertilizer: Feed with a diluted low nitrogen fertilizer during the growing season (spring to early fall). Avoid fertilizing in winter when the plant is dormant.

Pruning: Minimal pruning is required. Remove dead or dying leaves to keep the plant healthy and tidy.

Repotting: Repot every two to three years or when the plant outgrows its pot. Repotting provides fresh soil and room for growth.

Propagation: Easily propagated by seed or leaf cuttings. Allow any cut surface to callous over for a few days before planting in well-draining soil.

Pests and Diseases: Watch for common succulent pests like aphids, spider mites, or mealybugs. Treat infestations with insecticidal soap or neem oil. Be vigilant against fungal diseases, especially in humid conditions.
