Summary

Stomatium agninum, commonly known as Lamb’s Tongue, is an evergreen succulent native to the arid regions of South Africa, particularly the Eastern Cape. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), forming a low, spreading mound. The plant is characterized by its fleshy, tongue-shaped leaves that are often covered with fine hairs, giving it a distinctive texture. During the summer months, it produces bright yellow flowers that open at night and may attract nocturnal pollinators.

Lamb’s Tongue is valued for its drought tolerance and unique foliage, which adds textural interest to rock gardens, succulent collections, and xeriscaped areas. It is well-suited to cultivation in Mediterranean climates and other regions with dry summers. While it thrives in full sun or part shade, it requires well-draining soil to prevent root rot. Overwatering should be avoided, especially during the winter months when the plant is dormant. Lamb’s Tongue is relatively low-maintenance, making it a good choice for gardeners seeking water-wise plants.CC BY-SA 4.0
