Sedum nussbaumerianum, commonly know as Coppertone Stonecrop, is a low growing, evergreen, perennial, succulent subshrub with attractive rosettes of thick pointed leaves up to 2 inches (5 cm) long at maturity. The leaves are yellow-green in partial shade and turn rosy-gold to bright coppery red in full sun. Round clusters of slightly scented, white, starry flowers with pink anthers appear in spring.
Sedum nussbaumerianum is often confused with Sedum adolphii. They are similar in appearance and some botanists believe that the two should be lumped under the name Sedum adolphii. Robert Clausen in “Sedum of North America North of the Mexican Plateau” listed them as often confused but separate taxa.
Coppertone Stonecrop is best grown outdoors where it can be protected during the winter. It is hardy from USDA Plant hardiness zones 9 through 11. If grown inside, it tends not to thrive and will lose its beautiful copper color. It is a great choice for the rock or succulent garden or in a decorative container or hanging basket.
When growing Coppertone Stonecrop, keep in mind that plants need very little attention or care. A common name for Sedum is Stonecrop, due to the fact that many gardeners joke that only stones need less care and live longer.
Coppertone Stonecrop actively grows in cooler months. Tolerates light shade, but best color is obtained in the sun. It tolerates most soils but thrive in light, slightly sandy, well-draining soils. In soggy, water-logged soils, the roots rot and the plants suffer disease and pest problems.
Water as often as needed. Coppertone Stonecrop is drought tolerant once it establish a deep root system. It’s best to use the “soak and dry” method, and allow the soil to dry out completely between waterings. Fertilize annually with a balanced fertilizer. Apply the fertilizer to the soil in the spring as new growth appears, according to package directions.
Cut back stems and re-root when plants become too leggy. Divide Coppertone Stonecrop every 4 years to encourage new growth.
There are 3 ways to effectively propagate Coppertone Stonecrop: from seed, leaf cuttings and stem cuttings.
