Description
Hylotelephium maximum, also known as Hylotelephium telephium subsp. maximum, is a succulent plant that forms clusters of erect or ascending stems with drab green to brown-maroon leaves. The stems grow from a tuberous rootstock and can reach up to 32 inches (80 cm) in height. The leaves are egg-shaped, have blunt teeth on their margin, and can grow up to 4 inches (10 cm) long.
The flowers are creamy white, sometimes with a greenish, yellowish, pinkish, or purple tinge. They appear in clusters from late summer to fall.
Hylotelephium maximum was formerly known as Sedum maximum or Sedum telephium var. maximum.
How to Grow and Care for Hylotelephium maximum
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. maximum in an area of your garden that gets 6 hours of sunlight daily.
Soil: H. maximum 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 cold-hardy and tolerant of heat and drought, making it a popular outdoor succulent. H. maximum 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. maximum 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 the package directions, apply the fertilizer to the soil in spring as new growth appears.
Repotting: Plants in containers require little more care than those in gardens. Repot your H. maximum 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 seeds in spring. Dividing your H. maximum is easy and can be carried out almost any time in the growing season, though it is probably best done in spring or early summer. Propagate by stem cuttings in summer.
