$Orchis purpurea, the lady orchid, is a herbaceous plant belonging to the genus Orchis of the family Orchidaceae. It is native to Europe, northern Africa, Turkey and the Caucasus. The lady orchid is a terrestrial plant that grows in sloping woodlands, particularly in mixed deciduous / oak forests, but occasionally occur in meadows. It prefers limestone or chalk soil and partially shaded locations at an altitude of 0–1,350 metres (0–4,429 ft) above sea level.\n\nThe lady orchid is a perennial plant that grows to a height of 30–100 centimetres (12–39 in). The leaves are broad and oblong-lanceolate, forming a rosette about the base of the plant and surrounding the flower spike. They are fleshy and bright green, and can be up to 15 cm long. The inflorescence is densely covered with up to 50 flowers. The sepals and upper petals are violaceous or purple (hence the Latin name purpurea of the species). The flower's labellum is pale pink or white, with a center spotted by clusters of violaceous or purple hairs.\n\nThe lady orchid is pollinated by bees and flies. The flowers produce a scent that mimics the pheromones of female bees and flies. When a bee or fly visits the flower, it is tricked into collecting pollen on its body. The pollen is then transferred to the stigma of another flower when the bee or fly visits it to collect nectar.\n\nThe lady orchid is a rare plant in many parts of its range. It is threatened by habitat loss, fragmentation, and overcollection. The lady orchid is a protected species in some countries, including the United Kingdom and France.$
