About Faucaria Bosscheana
Faucaria bosscheana · also called white tiger jaws, Bossche's tiger jaws · houseplant
Faucaria bosscheana is a small South African mesemb that forms tight clumps of triangular leaves edged with soft, tooth-like projections resembling open jaws. The white-margined teeth give it the name white tiger jaws. A compact, slow-growing succulent, it produces large yellow daisy-like flowers in autumn and needs sharp drainage and a cool, dry winter.
Preferred mix: Very gritty mineral cactus mix
Watch for — Stretched, splayed leaves: Etiolation from too little light. The clump opens out and loses its jaw-like form. Move to full sun and reduce watering to encourage compact, firm growth.
Why faucaria bosscheana needs this mix
Faucaria Bosscheana is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Faucaria Bosscheana is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons faucaria bosscheana struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates faucaria bosscheana's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for faucaria bosscheana.
