It reaches a mature height of 0.5–1.2 m (approximately 1–3 feet). In early spring, it produces pinkish-purple
flowers in clusters of 2–6 together; each flower is 2–3 cm (approximately 1 inch) in diameter, with a five-lobed purple
corolla. The flowers are unusual in comparison with other species of the genus
Rhododendron found in northeastern North America. Most rhododendrons of the region have tubular flowers with 5
stamens each, while
R. canadense has 10 stamens housed inside a
zygomorphic corolla. The
leaves open only after the flowers have bloomed and wilted; they are narrow oval, 2–6 cm long and 1–2 cm broad. When not in flower, it can still be identified by its peculiar, orange-brown
seed cases, 1–1.2 cm long. == Distribution and habitat ==
