About
Ilex serrata, commonly known as Japanese winterberry or Fine-tooth holly (Ume-modoki in Japanese), is a deciduous holly native to Japan, China, and the Korean Peninsula. The plant is dioecious — only female plants produce the abundant small red berries that are the species' signature attraction. From late autumn through winter, the bare branches are densely studded with bright red berries, creating a striking 'coral in winter' effect highly valued in bonsai display. White-berried ('Shiro-ume-modoki') and yellow-berried forms also exist. The species requires ample sunlight for good berry production and prefers moisture-retentive soil.
