Viburnum sargentii

Viburnum sargentii or Kamboku (scientific name: Viburnum opulus var. sargentii ) is a deciduous shrub/small tree of the family Adoxaceae, native to East Asia. In Japan, it grows naturally in moist mountainous areas north of Hokkaido and central Honshu. It is 3-5 m tall and is a shrub in forests. The leaves are 5-11 cm long with serrated margins. The inflorescence is opposite, inverted egg-shaped, and has three large lobes at the tip. In June, it produces a diffuse inflorescence with bisexual flowers (0.4 cm in diameter) and 5-petaled ornamental flowers (2 cm in diameter). Both flowers are white. In September, it produces red spherical fruits with a diameter of about 0.8 cm, but they are not edible. The fruit contains many small seeds that are dispersed by the wind. Propagation is done by cutting or dividing the plant. It is used as a garden and park tree, and its wood is used for tools and toothpicks, and its fruits for medicinal purposes.

"Sargentii" commemorates the American botanist "Charles Sprague Sargent".
