Cassiope mertensiana is a species of flowering plant known by the common names western moss heather and white mountain heather. This heather is native to subalpine areas of western North America, from Alaska to the mountains of California. It is a small, branching shrub which forms patches along the ground and in rocky crevices. The short, erect, snakelike stems are covered in tiny leathery scalelike leaves only a few millimeters long. From between the layers of scale leaves emerge reddish pedicels each bearing a petite, hanging, down-facing, bell-shaped flower. The bractlets are red and the contrasting flower is white.
