Lithophytes are plants that grow in or on rocks.They can be classified as either epilithic (or epipetric) or endolithic; epilithic lithophytes grow on the surfaces of rocks, while endolithic lithophytes grow in the crevices of rocks (and are also referred to as chasmophytes).

It may be propagated readily from seed sown in the fall, or from tip cuttings taken in late spring and early summer. Space the plants about 4in apart, giving them plenty of growing room. Aurinia is widely available at garden centers, so home propagation is not really necessary unless you have an unusual form or need great numbers of plants.
Plants grown in strong light will develop hard strongly coloured skins which are resistant to damage and rot, although persistent overwatering will still be fatal. Excessive heat will kill potted plants as they cannot cool themselves by transpiration and rely on staying buried in cool soil below the surface. Commercial growers mix a mild ...
The plants cast their seeds in the soil during the growth period, but they do not germinate in the next season. Their hard coating is impermeable to the water, and thus the seeds remain dormant for a long period of time. This coating together with their small size allows these plants to establish a large seed bank rather deep in the soil.
