Caucasian Stonecrop Phedimus spurius 'John Creech'

John Creech Sedum is a herbaceous perennial succulent in the stonecrop family (Crassulaceae). It is evergreen in warm winter climates. It is native to Caucasus which is a region between Eastern Europe and Western Asia. The genus name derives from the Latin word sedeo which means to sit referring to their growth habit of sitting and sprawling over rocks. The specific epithet means false. It was collected at the Central Siberian Botanic Garden in 1971 by John Creech, former director of the U.S. National Arboretum.

It tolerates any soil including dry, poor soil that is not too moist in full sun. The John Creech Sedum grows best in sandy or gravelly soils to prevent overwatering. The plant will reach 6” tall and should be planted 12” apart. It spreads quickly to 24” due to stems that easily root with soil contact. Once it is established, it is drought tolerant. Light fertilization will quicken its growth. You can easily propagate it by division or cuttings planted in the soil.

This sedum is virtually disease and pest-free. It is resistant to deer and rabbits. The small star-shaped pink blooms occur in fall. The foliage is showy year-round (in warm winter climates). The leaves turn burgundy in the fall.

The John Creech Sedum can be used as a ground cover in naturalized areas, sunny slopes, rock gardens, and roof gardens. Due to their small size, it is best to plant in groups or masses. They can fill a border along a pathway or cascade over stone walls and containers.

Insects, Diseases, and Other Pest Problems: No significant problems. Slugs, snails, and scale can cause minor problems.
