Description
editPetrosedum rupestre plants are typically up to 10 cm high, with sprawling stems and stiff foliage resembling spruce branches, with softer tissue. The leaves are frequently blue-gray to gray but range to light greens and yellows; the flowers are yellow. Like many Sedum species, it has a prostrate, spreading habit.
Cultivation
editPetrosedum 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.[4]
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.[5]
Petrosedum rupestre is occasionally used as a salad leaf or herb in Europe, including the United Kingdom.[6] It is said to have a slightly astringent or sour taste.
