This species is native to Japan (Hokkaido).
Hylotelephium cauticola, formerly known as Sedum cauticola, is a mat-forming succulent with trailing stems that bear grey-green leaves with pink-tinged margins and purplish-pink flowers. It grows up to 3.2 inches (8 cm) tall. Leaves are round, bluntly toothed, up to 1 inch (2.5 cm) long, and up to 0.7 inches (1.8 cm) wide. Flowers are star-shaped, dark pink to purplish pink, up to 0.4 inches (1 cm) across, and appear in fall arranged in compact, corymb-like clusters.
The specific epithet "cauticola (kaw-tee-KOH-luh)" means "cliff-dwelling" or "growing on cliffs" and refers to the preferred habitat of the species. It is a compound of two Latin words, the noun "cautes," meaning "a rough, pointed rock," and the suffix "-cola."
How to Grow and Care for Hylotelephium cauticola
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. cauticola in an area of your garden that gets 6 hours of sunlight a day.
Soil: H. cauticola does not need rich soil, but it does need excellent drainage. Choose a commercial potting mix for succulents or make one yourself.
Hardiness: This plant has a tolerance to heat and drought and is cold-hardy, making it a popular outdoor succulent. H. cauticola 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 H. cauticola 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 in spring as new growth appears, according to package directions.
Repotting: Plants in containers do require little more care than those in gardens. Repot your H. cauticola when it outgrows its current pot by moving it out 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 seeds in spring. Dividing your H. cauticola is very 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.
