Tiger’s Jaw [Faucaria tigrina] lives up to its common name. The sharp spines that edge the pairs of speckled leaves look like the teeth of a ferocious tiger. Their unusual leaves make a spectacular addition to a succulent dish garden.
These South African succulents grow in clumps of stemless, star-shaped rosettes in its dry, rocky native habitat. Yellow, daisy-like flowers may appear on plants that are a few years old.
