Anyway, this is a "Lilium auratum", a type of lily which is called "yama yuri" in Japan. The name yuri is used to describe all lilies and comes from an old word, yuru, which means "swing". The lily was named for the way it swings in the breeze. Lilies were considered to be sacred in ancient times and there are festivals dedicated to the flower. Fifteen of the world's ninety six lily species are indigenous to Japan. Yama yuri means "mountain lily" as that is where it is often found, though it is also the most common lily here on the main island of Honshu.
The blossoms have a nice, light, sweet fragrance. Now that I know we have a yama yuri, I'll wait until it's done blooming and then move it to a more visible location - perhaps outside the kitchen sliding glass door - where we can enjoy it more.
