Sedum adolphii, Sedum nussbaumerianum
Sedum adolphi, also known as Sedum nussbaumerianum, is a lovely high-colored succulent that grows up to 8 inches (20 cm) tall. It is a rangy creeper, developing casual rosettes of yellow-green, football-shaped, up to 1.4 inches (3.5 cm) long leaves. When grown in the sun, they take on the orange-red highlights that make it a visual delight. As rosettes age, they produce new leaves at the center, shedding the oldest that drop off and root where conditions are right. From late winter to spring, appear the white, lightly fragrant flowers in flat-topped, umbel-like inflorescences.
USDA hardiness zones 9a to 11b: from 20 °F (−6.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Choose a location with full sun to filtered shade. Golden Sedums is an ideal plant for rock gardens because it spreads quickly with a trailing, low form. At maturity, it stands up to 10 inches (25 cm) tall and spread up to 2 feet (60 cm). Golden Sedum can also be used in mixed container gardens or even on walls or terraces.
This succulent tolerates most soils but thrives in light, slightly sandy, well-draining soils. In soggy, water-logged soils, the roots rot, and the plants suffer disease and pest problems. Plant Golden Sedum 2 feet (60 cm) apart. Combine this plant with other succulents or low-growing, drought-tolerant groundcovers.
Golden Sedum is drought tolerant once it establishes a deep root system. The best way to water this plant is to use the "soak and dry" method. Get the soil completely wet, and then wait until the soil is dry before watering again. Fertilize annually with a balanced fertilizer. Apply the fertilizer to the soil in spring as new growth appears, according to package directions.

Sedum adolphi is native to Mexico (Veracruz).
The late Henk 't Hart and Bert Bleij wrote the Sedum section in the lexicon "Illustrated Handbook of Succulent Plants: Crassulaceae" and noted Sedum nussbaumerianum to be very similar if not identical to S. adolphi. In "Sedum of North America North of the Mexican Plateau," Robert Clausen treated them as separate species in his book based on small differences in the inflorescences (S. nussbaumerianum has flowers all in the same plane, while S. adolphi has petals at different levels in cymes). However, the facts indicate that S. nussbaurianum should be regarded as a synonym of S. adolphi. The two plants have the same chromosome count, they came from plants grown from the same source (seeds gathered by Carl Purpus in 1907), and both have corymbiform inflorescences. With a priority of 12 years, Sedum adolphi is the valid name.
Though often seen with 2 "i"s, this epithet's proper spelling should have a single "i" as this is the genitive form of Adolphus, the Latinized name for Adolf Engler.
