Within the Aizoaceae family, there is a small group of succulents (+/- 28 species) including the genus Faucaria tigrina “Tigers Jaw Succulent” originating in the southern region of the African continent.
This group of plants is extremely popular among succulent plant collectors because of the beauty of its forms and flowering.
At present, numerous hybrids are offered because the species cross easily with natural form; This has made it very difficult to find type species (pure species can currently cost almost double or more compared to a hybrid given the low availability in the market).
They are characterized mainly by forming small compact rosettes with very succulent, opposite leaves, with or without tubers in the beam, with the presence of whitish or green spots, cylindrical to triangular and with conspicuously serrated margins (some varieties do not have a very obvious dentition ).
The shape of the leaves with the teething of the edges is very similar to an open mouth and that is why these plants are popularly known as jaws of a tiger or other animal.
The flowers are diurnal and open in the center of the rosettes. They are large compared to the size of the rosettes, arise solitary or in pairs and are bright yellow.
