Ixia; African corn lily

Japanese: イキシア（英語表記）Ixia; Aflican corn lily

A general term for the Ixia genus of the Iridaceae family. It is a bulbous plant with about 30 species that grow naturally in South Africa. It is easy to crossbreed, and many horticultural varieties have been developed. It has sword-shaped leaves and wire-like stems, and the flowers form spikes or panicles. The flowers of the almost same size and shape come in a wide variety of colors, including white, pink, red, scarlet, yellow, purple, and blue-green. Ixia viridiflora I. viridiflora is characterized by its metallic blue-green color, which gives it a metallic and mysterious look. It is cultivated as a semi-cold-hardy bulbous plant in flower beds and pots, and is also produced as cut flowers. The English name African corn lily comes from the fact that it is a weed in corn fields in its native land. It is planted in October, covered with about 5 cm of soil. During the frost season, frost protection such as a frame is necessary. If it is a potted plant, it should be brought indoors in winter. After flowering, when the leaves turn yellow, dig up the bulbs and store them.

アヤメ科イキシア属の総称。南アフリカに約 30種が自生する球根植物。交雑しやすく，多くの園芸品種が作出されている。剣状の葉と針金状の茎をもち，花は穂状または円錐花序を形成。ほぼ同形同大の花被片の色は，白，桃，赤，緋，黄，紫，青緑などと非常に多彩。なかでもイキシア・ビリディフローラ I.viridifloraは金属光沢のある青緑色で，金属的で神秘的な花色に特徴がある。半耐寒性球根植物として花壇や鉢植えで栽培されるほか，切り花としても生産されている。アフリカン・コーン・リリーの英名は，原産地でトウモロコシ畑の雑草になっているためという。 10月頃，5cmほど覆土して植付ける。霜のおりる季節は，フレームなどの霜よけが必要。鉢植えの場合は，冬期は室内に取込む。開花後，葉が黄変したら球根を掘上げ，保存する。
