Alternanthera ficoidea

Japanese: アキランサス（英語表記）Alternanthera ficoidea

A perennial plant of the genus Alternanthera in the Amaranthaceae family. Its Japanese name is Moyoubiyu. In horticulture, it is known by the name of a closely related genus, Akilanthus. It is also sometimes sold under the old genus name Terranthera. It has long, spatula-shaped leaves that grow opposite each other, and many species have red or yellow leaves or spots. It is often used as a supporting plant in flower beds from summer to autumn, but you can also enjoy its beautiful leaf color by planting it densely in a carpet-like pattern. It is naturally evergreen, but is not cold-resistant. It stops growing when the temperature drops below 10°C, and dies quickly if exposed to frost. To overwinter, keep it in a bright room at 5°C or higher. The leaf color becomes more vivid when exposed to direct sunlight. It can be propagated by cuttings from spring to summer.

ヒユ科アルテルナンテラ属の多年草。和名モヨウビユ。園芸的には近縁の別属名のアキランサスと呼ばれる。また，旧属名テランセラの名で流通することもある。細長いへら状の葉が対生し，葉が赤や黄に色づいたり，斑 (ふ) が入る種類が多い。夏から秋にかけての花壇の脇役としてしばしば縁植えなどに使われるが，毛氈状に一面に密植しても，美しい葉色を楽しめる。本来常緑であるが耐寒性はない。 10℃以下になると生育が止り，霜に当るとたちまち枯死する。越冬させたいときは，明るい室内で5℃以上に保つ。直射日光に当てると，葉色はより鮮かになる。春から夏にかけては挿木でふやすことができる。
