Japanese snowball bush; Viburnum plicatum var. plicatum
A deciduous shrub with showy, spherical clusters of white flowers. The name literally means 'golden-leaf handball', referring to the leaf color and flower shape.
I planted a Japanese snowball bush in the garden.
大手毬 (Viburnum plicatum var. sterile) has larger, sterile flower clusters and does not produce fruit, while 金葉手毬 is the fertile wild type with smaller blooms.
Compound of 金葉 (きんば, 'golden leaf') + 手毬 (でまり, 'handball'), referring to the golden-tinged foliage and the ball-shaped flower clusters.
