Phedimus kamtschaticus, formerly known as Sedum kamtschaticum, is a compact, low-growing groundcover that typically forms a foliage mat up to 6 inches (15 cm) tall and spreading indefinitely by trailing stems up to 18 inches (45 cm) wide. The leaves are thick, triangular, succulent, scalloped, dark green, and up to 1.5 inches (3.8 cm) long. They are deciduous at the stem bases but tend to be evergreen at the tips. Clusters of bright yellow, star-shaped flowers appear in summer. Flowers give way to small fruits, which turn brown-red in fall. Most of the foliage disappears in cold winter months.

How to Grow and Care

Phedimus will thrive in conditions that many other plants thrive in, but will do just as well in less hospitable areas. These succulents have a slow to moderate growth rate, making them a popular choice for growing as a groundcover. They also grow well in containers.

These are light-loving plants, growing best in full sun but also grow in light shade or partial shade. They grow best in warmer environments. Plant Phedimus in an area of your garden that gets 6 hours of sunlight a day.

The soil does need to be well-drained. Very good drainage is important for preventing root rot or fungal diseases.

The best way to water these plants is to use the "soak and dry" method. Get the soil completely wet and then wait until the soil is dry before watering again. Phedimus are drought-tolerant, so they bear well if you neglect them for a while.
