Growth Habit
Faucaria tigrina is generally stemless, though older plants may develop a short, woody base over time. Its clump-forming nature makes it ideal for container gardening and rockeries.
Natural Habitat and Ecology
Native Range
Endemic to South Africa’s Eastern Cape, particularly within the Albany Thicket and Karoo Desert, Faucaria tigrina thrives in rocky, clay-rich soils with a low pH (4.7–5.7).
Adaptations
Its toothed leaves serve an essential function—trapping moisture from fog and dew, enabling the plant to survive in arid conditions. This adaptation is crucial in its native environment, where water sources are scarce.
Conservation Note
Faucaria tigrina is endangered in the wild, with fewer than 1,000 mature plants remaining across four subpopulations. Urban expansion and habitat degradation threaten its survival.
Narrative
In South Africa’s rugged landscapes, Tiger Jaws clings to life, standing as a testament to nature’s incredible resilience.
