Ilex verticillata 'Winter Red' (f)

RHS

A dense, suckering, deciduous shrub, growing to 2m tall. This female cultivar has dark green, spine-tipped leaves that turn yellow in autumn, and clusters of small, white flowers borne in late spring. These are followed by long-lasting, intensely-red berries if pollinated by a male plant; the berries persist until late in winter
