屁糞葛(ヘクソカズラ) skunk vine

　葉などを傷つけると悪臭を放つので、屁糞などという不名誉な名前をつけられました。雑草扱いですが、花自体は可愛いと思います。

　When the leaves and other parts are damaged, it gives off a bad smell, so it was called shameful name, "hekuso", it means  fart and shit in Japanese. It is treated as a weed, but I think the flowers themselves are cute.
