Phedimus kamtschaticus, formerly known as Sedum kamtschaticum, is an attractive low-growing succulent that forms a mat of fleshy, rich green leaves on numerous spreading-ascending stems. It is a very variable species that grows up to 6 inches (15 cm) tall and spreads up to 18 inches (45 cm) wide by short, woody rhizomes. Leaves are about 2 inches (5 cm) long, usually with serrated edges. Most of the foliage disappears in the cold winter months. Flowers are star-shaped, bright yellow with orange anthers, and appear in clusters in summer.

The specific epithet "kamtschaticus" refers to the Kamchatka Peninsula.

How to Grow and Care for Phedimus kamtschaticus

Light: These light-loving plants will tolerate light shade or partial shade, but they prefer full sun and grow best in warmer environments.

Soil: Phedimus thrive in any well-drained soil. Good drainage is critical for preventing root rot or fungal diseases.

Hardiness: Phedimus kamtschaticus can withstand temperatures as low as -30 to 30 °F (-34.4 to -1.1 °C), USDA hardiness zones 4a to 9b.

Watering: The best way to water your Phedimus is to use the "soak and dry" method. Get the soil completely wet and then wait until the soil is dry before watering again.

Fertilizing: Feed with low-balanced fertilizer to keep your plants happy and healthy. Use a diluted dose of half the strength recommended on the package.

Repotting: Repot your plants when they outgrow their current pot by moving them out to a larger container to hold the plant better.
