Hydrangea or hortensia bloom roughly around May to July during the rainy season in Japan. Most are shrub like and one to three meters tall. This mophead flower with its large round flowerhead was in bloom the other day in our neighbourhood. 
Box is popular as ornamental plant, particularly for topiary because of its leaves and evergreen foliage. Instead of box, this hydrangea, which took about a week to dry, makes a nice table decoration.

This “mophead” flower is fabulous, and of course beautifully matched to the vase but I wouldn’t expect anything less from you!
