Epipactis is a terrestrial orchid native to European forests; the epipactis genus includes about forty species, generally terricolous, originating in Europe and central-northern Asia. They produce a large fibrous root, which over time extends to form dense colonies of plants, consisting of long erect, slightly arched, fleshy, bright green stems, slightly pubescent at the base, 60-70 cm high, at the apex of the which bloom in July-August, numerous flowers, up to thirty for each individual inflorescence, with greenish petals and sepals and characteristic cup-shaped labellum, slightly fleshy, pinkish-green in color; under each flower there is a small elongated bract of bright green color. At the base of the stems numerous arched leaves, linear, often with a dusty aspect, 10-15 cm long. E. gigantea has yellow flowers and stems even one meter long; E. mairei is native to China, with brown, yellow or greenish-white flowers.
These orchids need to be grown in a very bright location, even in full sun if the constant presence of water can be guaranteed, for example near a small pond; if grown in a container it is good to keep them in a bright but shady place, to avoid even short periods of drought. In general, epipactis do not fear the cold.
