Petrosedum forsterianum, formerly known as Sedum forsterianum, is a succulent plant with heads of yellow, star-shaped flowers at the ends of the upright branches. It grows up to 8 inches (20 cm) tall. The non-flowering shoots terminate in clusters of linear leaves (with old dead leaves persisting on the stem below). It is often mistaken for Sedum rupestre, 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 Sedums, keep in mind that these 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 because 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 usually enough to get the plant started there. They will send out roots from wherever the stem is touching the ground and root itself. If you would like to ensure further 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.
