Orchis militaris is a plant of the family Orchidaceae that is found in Europe.
Plant is found growing in dry calcareous substrate such as unfertilized lawns, meadows, edges and light woods up to 2600 meters in altitude. It is well distributed around Europe, reaching as far north as southern Sweden, but rather rare in the Mediterranean areas. It is extremely rare in Britain and a protected species, occurring only at the Rex Graham nature reserve in Suffolk and the Buckinghamshire Chilterns.
Plant blooms in the summer with a cluster of 2cm wide flowers. This plant grows to a height of 20 to 50cm with a robust stem with rather drawn up oblong basal leaves. The inflorescence forms a purplish dense cone consisting of from 10 to 40 flowers. In each flower the sepals and side petals are gathered together to form a pointed "helmet" (whence it gets its name), a lilac colour outside and a veined purple colour inside. The central tongue finishes in two lobes separated by a tooth.
Plants prefer well-drained low-fertility soils and areas with partial shade. This species is cool to intermediate growing. Water regularly. Divide plant when flower fades.
