Tongue-orchid
Serapias lingua L.

Serapias lingua, commonly known as the tongue-orchid, is a species of orchid native to the Mediterranean and parts of southwestern Europe. It is characterized by its distinctive tongue-like labellum and vibrant purple flowers. This orchid thrives in damp grasslands, marshes, and maritime sands, and is distributed across countries such as Portugal, Spain, France, Italy, and North African regions like Algeria and Morocco. The species was first described in 1753 by Carl Linnaeus and is a member of the Orchidaceae family.
Description
Serapias lingua is a terrestrial orchid with 2 to 5 tubers, one of which is sessile and the others attached to stolons, typically ovoid to subglobose in shape. The stem ranges from 10 to 25 cm in height, occasionally reaching 60 cm, and is marked by green, unspotted basal sheaths. The inflorescence is an elongated spike bearing 2 to 9 flowers, with bracts that are equal in length to the flowers and colored purple or, less commonly, greenish. The flowers measure 15 to 25 mm in size, with outer perianth segments that are ovate-lanceolate, acute, and concave, often displaying violet or purple hues, occasionally with greenish markings. The inner lateral segments are slightly shorter than the outer ones. The labellum is approximately twice the length of the other segments, featuring a solitary black ridge at its base. The lateral lobes are rounded and dark purple, hidden by the galea. The epichile is ovate-lanceolate, acuminate, and narrower than the hypochile, often directed forward, with a color range from violet to reddish, and occasionally yellow or white.
Habitat
Serapias lingua is typically found in damp grasslands, marshes, and maritime sands. These habitats are often characterized by high moisture levels and well-drained soils, which are essential for the orchid's growth and development. The species is adapted to the Mediterranean climate, with warm, dry summers and mild, wet winters, and is commonly found in coastal and lowland areas.
Cultivation
Cultivating Serapias lingua requires careful attention to its natural habitat conditions. It thrives in well-drained, moist soils with a high organic content. The plant prefers partial shade to full sun and benefits from a humid environment. When grown in cultivation, it is essential to mimic the natural seasonal variations, including a dry summer period to induce dormancy. Propagation is typically done through division of the tubers or from seed, though seed germination is challenging and requires specific mycorrhizal associations. Providing adequate air circulation and avoiding waterlogging are crucial for successful cultivation.
Uses
Serapias lingua is primarily valued for its ornamental beauty and is often cultivated in specialized orchid gardens and botanical collections. It is not widely used for commercial purposes, but it is appreciated by horticulturists and orchid enthusiasts for its unique floral structure and vibrant colors. In some regions, it may be used in ecological restoration projects to enhance native biodiversity in suitable habitats.
