Petrosedum rupestre, formerly known as Sedum rupestre or Sedum reflexum, is a mat-forming succulent with much-branched prostrate stems and small gray-green leaves. It grows up to 4 inches (10 cm) tall and spreads up to 24 inches (60 cm) wide. Leaves are stiff, juicy, linear with a pointed tip, and up to 0.8 inches (2 cm) long. Flowers are yellow, star-shaped, up to 0.5 inches (1.3 cm) across, and appear in terminal cymes in summer.
USDA hardiness zones 5a to 9b: from −20 °F (−28.9 °C) to 30 °F (−1.1 °C).
How to Grow and Care
When growing Sedums, keep in mind that these plants need very little attention or care. They will thrive in conditions many other plants thrive in but do just as well in less hospitable areas. They are ideal for that part of your yard that gets too much sun or too little water to grow anything else. A common name for Sedum is Stonecrop because many gardeners joke that only stones need less care and live longer.
Sedum is easily planted. Simply laying the plant on the ground where you want it to grow is usually enough to get the plant started there for shorter varieties. They will send out roots from wherever the stem is touching the ground and root itself. If you would like to ensure that the plant will start there, you can add a very thin covering of soil over the plant.
You can break off one of the stems for taller varieties and push it into the ground where you would like to grow it. The stem will root very easily, and a new plant will be established in a season or two.
