Hydrangea,Ajisai,アジサイ

This is the second installment of a two-part series on this topic.

紫陽花 (ajisai), hydrangea, is the deciduous shrub up to five feet high with ball-shaped clusters of bluish flowers in June and July. It has become a common ornamental throughout the world.

  In Japan both 額紫陽花(gaku ajisai), H. macrophylla and 沢紫陽花(sawa ajisai), H. serrata in particular have been cultivated for so many centuries that they have become part of the culture.

          Hydrangea!  in grove, being little garden,  the detached room
