 樹齢は不詳ですが、これほどのウツギの大木は日本において記録がありません。ウツギはアジサイ科の落葉低木で、ウノハナ(卯の花)とも呼ばれています。5から6月に白い花を咲かせ、この花は珍しい八重咲きです。各地に野生するほか、畑の生け垣にしたり観賞用に植えたりしています。茎が空洞のため空木と呼ばれ、「卯の花」の名は空木の花の意、または卯月(旧暦4月)に咲く花ともいいます。

  While its age is unknown, there are no records in Japan for any other bridal wreaths this large. A member of the hydrangea family, it is a deciduous shrub also known as "unohana" in Japan. This variety produces uniquely doubled white flowers, which bloom from May to June. Bridal wreath grows wild around the country, and is often planted as a hedge around farm fields and in gardens for ornamental purposes. The Japanese name for bridal wreath is "utsugi", which means "hollow tree". It derives from the fact that the trunk and branches are hollow in the center.
