Sedum reflexum or Sedum rupestre, also known as reflexed stonecrop, Jenny's stonecrop, blue stonecrop, stone orpine, prick-madam and trip-madam, is a species of perennial succulent plant of the genus Sedum, native to northern, central, and southern Europe. It is also known as Petrosedum reflexum.
The Sedum reflexum 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 most other Sedum species, it has a prostrate, spreading habit.
Sedum reflexum 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.
