Origin
Rhodiola cranging native to central Asia, western Siberia, and western and central China. It grows on stony soils and rocks in alpine regions at elevations ranging from 8,530 to 16,080 feet (2,600 to 4,900 m).
Description
Rhodiola coccinea is a cushion-forming succulent with thick rhizomes basally tapering into carrot-like roots and 2 to 10 simple flowering stems from each rhizome branch. The flowering stems are erect, brownish or purplish-red, and can reach up to 2 inches (5 cm) tall. Old flowering stems are persistent. The leaves are smooth, green, linear to linear-lanceolate, measuring up to 0.3 inches (0.7 cm) long and 0.06 inches (0.15 cm) wide.
The flowers are unisexual, 4- or 5-merous, red or rarely yellow, and appear in terminal, few-flowered clusters in summer.

How to Grow and Care for Rhodiola coccinea
Hardiness: USDA hardiness zones 4a to 9b: from -30°F (-34.4°C) to 30°F (1.1°C).
When growing Sedums, keep in mind that these plants need very little attention. They will thrive in conditions in which many other plants thrive, but do just as well in less hospitable areas. They are ideal for that part of your yard that gets too much sun or too little water to grow anything else. Sedum is commonly called Stonecrop because many gardeners joke that only stones need less care and live longer.
Sedum is easily propagated. Simply laying the plant on the ground where you want it to grow is usually enough to get it started for shorter varieties. They will send out roots from wherever the stem touches the ground and the root itself. If you would like to ensure the plant starts there, you can add a very thin layer of soil over it.
You can break off one of the stems for taller varieties and push it into the ground where you want to grow it. The stem will root very easily, and a new plant will be established in a season or two.
