"Epipactis gigantea" is a species of orchid known by the common names stream orchid and giant helleborine. This wildflower is native to western North America from western Canada to central Mexico. This is one of the most abundant orchids of the Pacific coast of North America. This is an erect perennial reaching anywhere from 30 centimeters to one meter in height. Its stems have wide or narrow lance-shaped leaves 5 to 15 centimeters long and inflorescences of two or three showy orchids near the top. Each flower has three straight sepals which are light brownish or greenish with darker veining, each one to two centimeters long. The two top petals are similar in shape and reddish-brown with purple veins. The lowest petal is cup-shaped with a pointed, tongue-like protuberance and is brighter red-brown and more starkly veined, often with areas of yellow. The fruit is a hanging capsule 2 or 3 centimeters long which contains thousands of tiny seeds. This plant grows in wet areas in a variety of habitats, including riverbanks, hot springs, and meadows. Unlike some of its relatives, this species is an autotroph.
