Sedum (English spelling) Sedum; orpine; stonecrop

Japanese: セダム（英語表記）Sedum; orpine; stonecrop

A general term for the succulent genus Sedum, Crassulaceae. Approximately 500 species are known in the temperate and subtropical zones of the Northern Hemisphere. In Japan, the red-flowered Sedum, the yellow-flowered Sedum, and the stonecrop are found. The first two groups have underground rhizomes, and the above-ground parts usually die in winter. On the other hand, the stonecrop family does not have thick underground stems, is evergreen in winter, has small leaves, and is excellent as a ground cover plant. It is often used as a garden plant because there are many species that are beautiful, cold-resistant, sturdy, and easy to grow. Mexican stonecrop, which has four whorled leaves, has become particularly popular in recent years. On the other hand, Taitogome, which has alternate rice-grain-shaped leaves, grows wild on the coasts of the Kanto region and west, and is highly cold-resistant. It prefers sunny environments, many of which are drought-resistant, and can be easily propagated by cuttings.

ベンケイソウ科の多肉植物セダム属の総称。北半球の温帯から暖帯に約 500種が知られる。日本では，赤花系のベンケイソウ，黄花のキリンソウやマンネングサがみられる。前2群は地下に根茎があり，普通冬は地上部が枯れる。一方，マンネングサの仲間は太い地下茎をもたず，冬も常緑で葉が小さく，グラウンドカバー植物としてすぐれている。花が美しく，耐寒性があり，じょうぶで育てやすい種類が多いため，園芸植物としてよく利用される。葉が4輪生するメキシコマンネングサが近年は特に普及している。一方，米粒状の葉が互生するタイトゴメは，関東地方以西の海岸に自生し，耐寒性が強い。日当りのよい環境を好み，多くは乾燥に強く，挿木で容易にふやすことができる。
