Hylotelephium spectabile 'Carl', Sedum 'Carl', Sedum spectabile 'Carl'
The parentage of this hybrid is unclear but thought to be a result of the cross between Hylotelephium spectabile and Hylotelephium telephium. It was found amongst a batch of Hylotelephium spectabile 'Meteor' and introduced by Joe Sharman, who owns Monksilver Nursery in Cottenham, a village in Cambridgeshire, England.
Hylotelephium 'Carl', formerly known as Sedum 'Carl', is a succulent plant that forms a compact clump of thick fleshy gray-green leaves on upright stout reddish stems. It grows up to 18 inches (45 cm) tall with a spread of 24 inches (60 cm). The leaves are rounded and slightly serrated. Clusters of long-lasting brilliant magenta-pink star-shaped flowers appear on reddish stems from late summer to fall.
How to Grow and Care for Hylotelephium 'Carl'
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. 'Carl' in an area of your garden that gets 6 hours of sunlight a day.
Soil: H. 'Carl' 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. 'Carl' 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. 'Carl' 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. 'Carl' 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. 'Carl' 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.
