ここで見られる植物:モチツツジ(Big Sepal Azalea; Rhododendron macrosepalum)

モチツツジは本州や四国の低山地や丘陵地などで育つ常緑低木です。モチツツジの名は、粘り気が餅に似た、柄と萼のネバネバした表面から来ています。高さはおよそ60cmから2mまでと大きくばらつくこともあり、枝の先には楕円形または細長い葉が密生しています。4月から6月の間に新芽が出ると、それと同時に葉のわきに淡赤紫色の花が咲きます。花は漏斗状の形をしており、内側の上面には蜜標とよばれる、虫を引き寄せる働きをもつ特徴的な赤い斑点模様があります。


Local Plants: Mochitsutsuji (Big Sepal Azalea; Rhododendron macrosepalum)

This evergreen shrub grows in low mountainous regions and hilly areas on the islands of Honshu and Shikoku. The mochitsutsuji name comes from the sticky surface of the stem and calyx, resembling the stickiness of mochi rice cakes. The height may vary considerably, between roughly 60 centimeters and 2 meters, with oval or elongated leaves clustered together at the ends of its branches. In April to June, at the same time as new shoots appear, light red-purple flowers bloom beside the leaves. The flowers feature a funnel-like shape with a distinctive red-speckled pattern on the upper part of their interior, called a nectar guide, that attracts insects.
