It is native to northern China and along the Pacific coast of Siberia including Kamchatka Peninsula.\nThick, triangular, succulent, spatulate to obovate, semi-evergreen, dark green leaves are deciduous at the stem bases but tend to be evergreen at the tips. Tiny, star-shaped, yellow flowers bloom in flat cymes in June-August. Flowers give way to small fruits which turn red in fall.
