Byakudan is a very common “string cactus”, and if you cut it vaguely and insert it in the soil, it will increase as much as you want. However, it is not easy to make flowers bloom. Even if you grow up with tender care, it does not bloom, but rather if it is completely dried by being exposed to the cold wind and even if it wilts out, you will leave it, it will bloom so beautiful now. This Byakudan has blossomed on a splendid stone wall without the master because none take care of it.

白檀はごくありふれた「ひもサボテン」で、適当に切って土に挿しておけばいくらでも増えます。しかし、花を咲かせるのは容易ではありません。可愛い可愛いと育てたからといって花を咲かせるものではなく、かえって寒風に晒されて完全に乾燥し、萎み切っても放って置くと今頃こんなに綺麗な花を咲かせます。雑草が生い茂る、主人なきこの立派な石垣にだからこそ、白檀は花を咲かせたのです。
