トキワツユクサの来歴
トキワツユクサはツユクサ科の常緑多年草。原産地は南米です。日本へは昭和時代の初期に園芸植物として渡来。当初は葉に白い斑が入っていましたが、逸出後に変異し、斑が消えました。樹下や水辺など湿気の多いところから、野原や畦道など日当たりの良いところまで広範に自生。
トキワツユクサの名前
トキワツユクサの名前の由来は冬に地上部が枯れない露草だから。常磐は「常緑」という意味です。日本に移入されたときは「白斑葉博多唐草」でしたが、野生化して白斑がなくなり、「野博多唐草」に。英名の「彷徨えるユダヤ人」は赦されるまで地上を歩き続ける伝説上の人です。

Wandering Jew
History of Wandering Jew
Wandering Jew is an evergreen perennial of the Commelinaceae family. The place of origin is South America. It came to Japan as a horticultural plant in the early Showa period. Initially, the leaves had white spots, but after they escaped, they mutated and the spots disappeared. It grows widely from humid places such as under trees and waterside to sunny places such as fields and ridges.
Name of Wandering Jew
The origin of the name of evergreen dayflower is that the above-ground part does not die in winter. When it was introduced to Japan, it was “Variegated leaf Tradescantia fluminensis”, but it became wild and the variegation disappeared, and it became “Tradescantia fluminensis”. The English name “Wandering Jew” is a legendary person who keeps walking on the ground until he is forgiven.
Figure of Wandering Jew
The stem of Wandering Jew crawls on the ground and roots from the node. The leaves are long, pointed oval and opposite. It is similar to the dayflower. The flower has a floral pattern from the axil and is a small triangle with three white petals. There are 8 stamens. The filaments are white, the anthers are yellow, and the long cilia are dense. The flower language is “respect”, but it is a foreign organism that needs attention.
