How to Grow and Care

The various species make excellent pot subjects and have been cultivated in Europe for over 300 years. Some species, such as Faucaria tigrina, are quite hardy, while others can be prone to stem rot.

Faucarias are mostly spring and fall growers. They need good drainage, but with a little shade, they will do just fine even with extreme heat, although they do stop growing then, and they need water every few days. When they lack water, like many other mesembs, the stems die, and some of the rosettes are not connected to the roots by any living tissue. When found in time, the rosettes can be used as cuttings and keep in the shade in a barely moist medium until the temperature cools down in the fall.

They bloom for several months in the fall or the beginning of winter. The flowers open around midday and close in the late afternoon. They often don't open if the weather is cloudy or if they are in the shade. See more at How to Grow and Care for Faucaria.


Faucaria felina subsp. tuberculosa is native to South Africa (Cape Province).
