學名：Liparis nigra Seidenf.
A perennial herb in the genus Liparis, native to the foothills of the Himalayas and the Indochina Peninsula, also distributed in Taiwan. The terrestrial orchid is 15~25cm tall, with cylindrical fleshy stems up to 1 cm in diameter. Leaves 3~6, oblique ellipse, ovate ellipse or ovate oblong in shape, 9~17cm long and 3.5~10cm wide. Racemes, more than 20 flowers in each inflorescence, dark purple-red. The linear petals and calyx petals are narrow while the oval labellum petals are about 1cm wide. Flowering from late spring to early summer.
The terrestrial orchid thrives in a warm and partial-sun environment and prefers media such as loam mixed with mulch and peat soil to increase organic matter. Water once the soil slightly dries. Apply a slow-release compound fertilizer once in spring and autumn. Propagated by division.
The hardy plant is easy to bloom and is an excellent ground cover plant for shady spaces, especially in building shades and atriums. The peculiar shape and unique color of the flowers is distinctive among the common orchids. Cultivars with variegated foliage are bred to increase the ornamental value.
