These are very interesting plants, stemless, and forming clumps. They have very fleshy roots. The growths form rosettes of 6 to 8 glaucous green to purplish leaves, covered with roundish warts. The flowers are yellow or orange. The growing period is in summer and all species require as much light as possible. Water can be given frequently in summer, but they should be kept dry in winter. They are easily propagated from seed.

The compost should be very sandy. The genus is native to S. Africa and Great Namaqualand.

Titanopsis calcarea. An interesting species, the leaves having the appearance of pieces of limestone. It forms rosettes of grey-green to purple leaves with whitish or rosy warts towards their broadened tips. Great care should be exercised to see that no water lodges between the leaves, for these will rot. The flowers are orange, and produced on short stalks.

Titanopsis Fulleri. A beautiful plant with rosettes formed of 5 or 6 pairs of leaves, which terminate in a roundish triangular tip; the backs of the leaves are roundly keeled, the upper surface flat and slightly concave. The leaves are a beautiful blue-green with a reddish tinge, the surface covered with dark dots. This wart-like roughness can vary in colour from almost pure white to purple. Flower, yellow.

Titanopsis setifera. This is a distinctive species, having leaves thicker and greener than the others in the genus. The little warts are not so prominent, but small teeth protrude on the edges, and also a few on the upper and under surfaces.
