Summer green, flowers purple-red. Reblooming from new shoots all summer long. Leaves obovate about 4 cm long and 2 cm wide. Extremely hardy. In July 1964, Dietrich G. Hobbie found this beautiful species above the tree line at 400 m above sea level. on the Alaska Peninsula (Mnt. Katmai Nat. Monument) between dwarf willows and birches, Empetrum nigrum, Arctostaphylos and other dwarf trees in an open location on volcanic rock in humus cracks. He made another find above Nome in the Kugluaik Mts., above the gold fields in the tundra on frosty ground, combined with dwarf trees and low perennials. Temperatures there drop to 50°C and below, with little snow in the pre-winter. Rh. camtschaticum appears to us to be very valuable as a ground cover and for the rock garden, both in partial shade and in full sun, with sufficient soil moisture. Mid-June.
