General Description: Candystick has pink and white-striped stems, 1-4 dm high and 5-10 mm thick. Stems are clothed in white to pinkish, alternate, lance-shaped leaves that are largest near mid-stem. Flowers are borne in tight clusters in the axils of the upper leaves (bracts). Each flower has 5 separate white to pinkish sepals, ca. 5 mm long, and 10 purple stamens. Petals are lacking. The 5-lobed ovary matures to form a many-seeded capsule.
Diagnostic Characteristics: The pink and white stems lacking green leaves are distinctive.
Habitat Comments: Deep humus or partially decomposed logs, generally in the shaded areas of old growth coniferous forests at 2300-6700 feet.
