Japanese Water Iris (Iris Ensata) ハナショウブ（花菖蒲）

英語の後に日本語が続きます。

This is a Japanese water iris (Iris ensata). The contrast between deep purple and yellow is so beautiful. The irises grow in wet land and flower in June and therefore its name "hana shoubu" is used as a kigo (i.e., a word or phrase associated with a particular season used in haiku) that represents early June to early July. Japanese water irises produce flowers of more than 500 colors.

I saw this Algerian iris (Iris unguicularis) in Central Tokyo. The contrast between pale purple and yellow is so beautiful. I thought it strange for an iris to flower in winter, but it's understandable. Algerian irises produce flowers in winter and that's why they're called "iris flowering in winter" in Japanese.
