Faucaria felina subsp. tuberculosa, Mesembryanthemum tuberculosum
Faucaria tuberculosa, also known as Faucaria felina subsp. tuberculosa, is a clump-forming succulent that grows up to 6 inches (15 cm) tall. Leaves are dark green with whitish dots and patches, scattered in rough white tubercles over the upper surface, and have edged with soft white structures that look like teeth. They are ovate-triangular in the top view, up to 1 inch (2,5 cm) long, up to 0.8 inches (2 cm) wide, and arranged in opposite pairs. Flowers are yellow, daisy-like, and up to 1.6 inches (4 cm) in diameter.
This species is very similar to and often confused with Faucaria tigrina. It can be identified by the tubercles on the leaves, which are unique in the genus.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
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 tuberculosa is native to South Africa (Cape Province).
