お茶室のわきでカヤツリグサが見られます。道端などに生えるカヤツリグサ科の一年草です。和名は蚊帳吊り草の意味で、茎を両端から割くとできる四角形を、蚊帳を吊る四角い枠組みに見立てたものです。

"Kayatsurigusa" plants can be seen by the tea house. They are annual plants in the Cyperaceae family that commonly grow along roadsides. The Japanese name comes from the fact that, when the stem is split from both sides, it forms a square shape resembling the frame of a traditional mosquito net, which is called "Kaya" in Japanese.
