About
Rhodiola integrifolia is a species of flowering plant in the stonecrop family known by the common names ledge stonecrop, western roseroot, and king's crown. It is native to north-easternmost Russia, including Kamchatka, and western North America, where it grows in mountainous habitat in subalpine and alpine climates, including meadows, cliffs, and talus. It is a perennial herb producing a stout stem from a fleshy, branching caudex, reaching a maximum height near 30 centimeters. The fleshy leaves are alternately arranged on the stem, widely lance-shaped to oval and pointed, flat but upcurved toward the tip, reaching 2.5 centimeters long. They are green when new and age to orange, rose, or red. The inflorescence is a dense cyme of up to 50 flowers with fleshy petals in shades of bright red to deep purple. The fruits are red, rounded ovals with pointed tips.
