Epipactis, or helleborine, is a genus of terrestrial orchids consisting of approximately 70 species. This genus is abbreviated as Epcts in horticultural trade.
Their creeping, fleshy rhizomes grow offshoots, from which then emerge the 20–70 cm long stems during the next spring.
There are four to eight alternate, lanceolate leaves, that grow progressively shorter near the top. The margins are entire, the top is acute. Species with less chlorophyll have blue-purple leaves.
Their bilaterally symmetrical colorful flowers grow from a terminal raceme. The three sepals and the two lateral petals are ovate and acuminate. Their color can vary from greenish-white to violet and purple.
The lip is divided in a bowl-shaped hypochile, with the outer surface greenish-white and threaded with dark veins. The wavy, snow-white epichile is fan-shaped.
The ovary is inferior. It produces a dry capsule with countless minute seeds.
