Culture
Easily grown in average, dry to medium, well-drained soils in full sun. Thrives in sandy to gravelly soils of moderate to low fertility. Tolerates some light part shade in hot summer climates, but will produce weak floppy growth when grown in too much shade or in overly rich soils. Needs good soil drainage to perform well. Drought tolerant. Propagate by divisions in spring or stem cuttings in summer. Detached leaves can be rooted in soil to form new plants. Plants may be cut back in late spring to control height.
Noteworthy Characteristics
Hylotelephium is a genus of about 33 species of drought-tolerant herbaceous perennials native to Asia, Europe and North America. They are commonly called stonecrop and are excellent plants for fall gardens. Many species and hybrids were formerly place in the genus Sedum.
Genus name probably honor Telephus, King of Mysia and son of Hercules.
Many hylotelephiums and sedums are commonly called stonecrop in reference to the frequent sighting of the genus in the wild growing on rocks or stony ledges.
'Pure Joy' was bred by Brent Horvath of Intrinsic Perennial Gardens in Hebron, Ill. in 2005 and introduced in 2011 by Proven Winners®. It was raised as a seedling from open pollinated seed sown from an unnamed, unpatented Sedum tatranowii and is a member of the Walters Garden, Inc. ROCK 'N GROW® series. In spring, 'Pure Joy' forms a compact mound of blue green foliage that matures to a semi-upright clump of lighter gray green foliage. In late summer, it is covered with bi-color pink flowers followed by deeper pink seed heads. 'Pure Joy' grows 3/4 to 1 ft. tall and 1 1/4 to 1 3/4 ft. wide. It may also be sold under the name Sedum 'Pure Joy'. United States Plant Patent #PP24,194 awarded January 21, 2014.
Problems
Slugs, scale, mealybugs, nematodes, aphids and weevils may appear. Rotting out is possible in wet and/or poorly drained conditions. Taller sedum hybrids with large flower heads are susceptible to flopping. This can be avoided by providing full sun conditions and planting in soils that are not too moist or rich. Pinching in spring can also force stems to grow thicker and bushier.
Uses
Rock gardens or border fronts. Specimen or groups. Containers.
