This subspecies is native to meadows and river margins in northeastern Europe.
Hylotelephium telephium subsp. ruprechtii, also known as Hylotelephium maximum subsp. ruprechtii, is a succulent plant with opposite nearly circular leaves lobed like the shape of a heart and wrapped around the decumbent or procumbent stems. The stems grow up to 16 inches (40 cm) long. Leaves are glaucous blue-green, tinged red on the margins ranging from almost entirely to quite deeply toothed on the same plant. Flowers are whitish to yellow-white with pink-tinted edges and appear from late summer to fall. In winter, the foliage dies back to the ground, and new growth appears in spring.
The subspecific epithet "ruprechtii (roo-PREK-tee-eye)" honors Franz Josef Ruprecht (1814–1870), an Austrian-born physician and botanist active in the Russian Empire, where he was known as Frants Ivanovič Ruprekht.
How to Grow and Care for Hylotelephium telephium subsp. ruprechtii
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. telephium subsp. ruprechtii in an area of your garden that gets 6 hours of sunlight a day.
Soil: H. telephium subsp. ruprechtii 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 is tolerant of heat and drought and is cold-hardy, making it a popular outdoor succulent. H. telephium subsp. ruprechtii 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. telephium subsp. ruprechtii 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. telephium subsp. ruprechtii 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. telephium subsp. ruprechtii 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.
