How to care for Tiger Jaws
Faucaria tigrina · Aizoaceae
Pairs of thick triangular leaves lined with soft, harmless teeth open like gaping jaws, giving this small South African succulent real character in a tiny pot. The 'fangs' are actually flexible hairs that help condense fog in habitat. In autumn, good light is rewarded with surprisingly large golden-yellow flowers. Water roughly every 16 days while it's growing (about every 35 in winter), give it direct sun, kept above 45°F (7°C) — dry air is fine for it.
Care at a glance
Water deeply once the soil has been dry for a few days, easing off sharply in winter.
A few hours of direct sun keeps the rosettes tight and triggers autumn flowering; a south or west sill is ideal.
Dilute cactus fertilizer once or twice during spring and summer.
Mistakes that kill this plant
- Winter watering at tropical-houseplant frequency.
- Dense, peaty soil around the fleshy base.
- Dim placement that slowly starves and stretches it over a season.
Seasonal tips
- Expect flowers in autumn — they open in afternoon sun and close at night.
- Keep it cool and quite dry in winter; it tolerates chilly bright rooms well.
- Repot rarely and shallowly in a gritty mix; it resents root disturbance.
