Petrosedum forsterianum is a succulent perennial up to 8 inches (20 cm) tall, with heads of yellow, star-shaped flowers on the ends of the upright branches. The non-flowering shoots terminate in clusters of linear leaves (with old dead leaves persisting on the stem below). Often mistaken for Sedum rupestre, which is a similar but more robust species found in identical habitats, and differing in having no dead leaves below the terminal clusters.

How to Grow and Care

When growing Sedum, keep in mind that Sedum plants need very little attention or care. They will thrive in conditions that many other plants thrive in, but will 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, due to the fact that many gardeners joke that only stones need less care and live longer.

Sedum is easily planted. For shorter varieties, simply laying the plant on the ground where you want it to grow is normally enough to get the Sedum plant started there. They will send out roots from wherever the stem is touching the ground and root itself. If you would like to further ensure that the plant will start there, you can add a very thin covering of soil over the plant. For taller Sedum varieties, you can break off one of the stems and push it into the ground where you would like to grow it. The stem will root very easily and anew plant will be established in a season or two… – See more at: How to Grow and Care for Sedum.


Native in southern Great Britain and the European continent. Established on old stone walls.
