Hylotelephium verticillatum var. verticillatum, Hylotelephium verticillatum f. bulbiferum, Hylotelephium verticillatum f. verticillatum, Hylotelephium viridescens, Sedum shimizuanum, Sedum taquetii, Sedum telephium f. verticillatum, Sedum telephium subsp. verticillatum, Sedum verticillatum, Sedum verticillatum f. bulbiferum, Sedum viridescens
This species is native to Russia (eastern Siberia, Kamchatka, Sakhalin, Kuril Islands), northern China, Korea, and Japan. It occurs on grassland slopes, shady, moist places on the sides of ravines at elevations between 2,950 and 9,510 feet (900 and 2,900 m).
Hylotelephium verticillatum, formerly known as Sedum verticillatum, is a succulent plant with simple, erect stems and usually glaucous leaves, mostly in whorls of 4 or 5. The stems grow up to 6.6 feet (2 m) tall. Leaves are elliptic to narrowly ovate or broadly lanceolate, with sparsely toothed margins, and on up to 0.4 inches (1 cm) long petioles. They are up to 3.2 inches (8 cm) long and up to 1.4 inches (3.5 cm) wide. The basal leaves are usually in whorls of 3 or opposite. Flowers are greenish to yellowish-white and appear in terminal or axillary clusters in summer. In winter, the foliage dies back to the ground, and new growth appears in spring.
The specific epithet "verticillatum (ver-ti-si-LAH-tum)" is the neuter form of the Latin adjective "verticillatus," meaning "having whorls; verticillate" and refers to the whorled leaves.
How to Grow and Care for Hylotelephium verticillatum
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. verticillatum in an area of your garden that gets 6 hours of sunlight daily.
Soil: H. verticillatum does not need rich soil, but it does need excellent drainage. Choose a commercial potting mix for succulents, or make one yourself.
Temperature: This plant is tolerant of heat and drought and is cold-hardy, making it a popular outdoor succulent. H. verticillatum 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. verticillatum 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. Apply the fertilizer to the soil according to the package directions in spring as new growth appears.
Repotting: Plants grown in containers require a little more care than those in gardens. Repot your H. verticillatum 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. verticillatum 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.
