Cranberrybush is a naturalized shrub found in the high Cascade Range in spring-fed montane riparian and meadow habitats at elevations of 300 to 900 meters.

Growing with branches that reach a moderate height, the shrub has widely elliptic leaves divided into three distinct lobes with serrated edges. Its leaves feature petioles with large glands and blades 4 to 12 centimeters long, creating an intricate foliage pattern. The fruit develops as an ovoid structure 6 to 12 millimeters long, transitioning from yellow to orange-red as it matures.
