Ilex serrata, known as Japanese deciduous holly, is a shrub native to China and Japan that reaches a height of 4.5 meters. The leaves are elliptical, with a toothed margin, and a dull green colour. The flowers are pink, and the berries are red. It is widely cultivated as a bonsai, as it tolerates pruning very well, as well as weak frosts (down to -5ºC). The most common style is the informal upright (Moyogi) although it fits many others.
