Petrosedum rupestre is a popular
ornamental plant, grown in gardens, containers, and as houseplants. It is drought-tolerant. There are named cultivars with
variegated (multi-colored) leaves. Through
vegetative cloning it is propagated from cuttings. This sedum is prone to
fasciation (cristate forms), which produces attractive cactus-like forms, with irregular curves. However it reverts easily, so all normal offshoots need to be removed quickly to maintain the cristate form.
Petrosedum rupestre is occasionally used as a salad leaf or herb in Europe, including the United Kingdom. It is said to have a slightly
astringent or
sour taste. ==References==
