Etymology
The specific epithet "caucasicum (kaw-KAS-ee-kum)" means "belonging to the Caucasus" and refers to the Caucasus, also known as Caucasia, which is the natural habitat of this species.
Origin
Hylotelephium caucasicum is distributed mainly in the Caucasus region. So far, it has been reported from Armenia, Georgia, Russia, Iran, and Turkey.
Description
Hylotelephium caucasicum, formerly known as Sedum caucasicum, is a succulent plant with fusiform roots and unbranched, erect to ascending stems with 9 to 20 pairs of opposite green or purplish leaves. The stems can grow up to 20 inches (50 cm) long. The leaves are obovate, moderately auriculate at the base, with margins obscurely and irregularly crenulate. They can measure up to 2.8 inches (7 cm) long and 2 inches (5 cm) wide.
The star-shaped flowers are greenish-white and appear in a dense corymbose panicle in summer and fall. In winter, the foliage dies back to the ground, and new growth appears in spring.
Hylotelephium caucasicum is closely related to Hylotelephium telephium. They look similar, and it is often difficult to distinguish one from another.
How to Grow and Care for Hylotelephium caucasicum
Light: This succulent prefers full sun. It tolerates light to partial shade in hot summer climates but will produce weak, floppy growth when grown in too much shade. Plant your H. caucasicum in an area of your garden that gets 6 hours of sunlight daily.
Soil: H. caucasicum does not need rich soil but requires excellent drainage. Choose a commercial potting mix for succulents, or make one yourself.
Temperature: This plant is cold-hardy and tolerant of heat and drought, making it a popular outdoor succulent. H. caucasicum can withstand temperatures as low as -30 °F (-34.4 °C). USDA Plant Hardiness Zones 4a to 9b, -30 to 30 °F (-34.4 to -1.1 °C).
Watering: The best way to water H. caucasicum is to use the "soak and dry" method. Get the soil completely wet, and then wait until it is dry before watering again.
Fertilizing: Feed annually with a balanced fertilizer. According to package directions, apply the fertilizer to the soil in spring as new growth appears.
Repotting: Plants in containers require little more care than gardens. Repot your H. caucasicum when it outgrows its current pot by moving it to a larger pot to hold the plant better. Spring is the best time to repot this plant. Make sure the soil is dry before you begin the repotting process.
Propagation: This succulent can be grown from seeds, division, or stem cuttings. Sow the seeds in spring. Dividing your H. caucasicum is easy and can be carried out at almost any time in the growing season, though it is probably best done in spring or early summer. Propagate by stem cuttings in summer.
