A perennial plant of the orchid family (APG classification: Orchidaceae). A type of oriental orchid. The leaves are slender, 50 cm long, dark green, glossy and leathery. The linear leaves grow straight up, and the tips are flexibly curved. The flower stalk grows in clusters between the leaves from November to January of the following year, reaching 40 to 50 cm, and produces 5 to 12 flowers in a cluster. The flowers are fragrant, 5 to 6 cm in diameter, and have reddish-brown stripes. The thin, pointed outer petals spread out, and the inner petals protrude. The ligule is three-lobed, and the anterior lobe curves backward from the bottom. It grows wild from the southern part of the Chubu region of Honshu to Okinawa, but is becoming less common. Horticultural varieties include Gekko, which has sandy spots scattered on the ligule, Sekko, which has a white border, Hiragasane, as well as Nankoku and Orizuru. Repotting should be done in April, May or October. [Masao Inomata May 21, 2019] Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
