Leaves bright green above, greyish below during the summer months, changing to brilliant red in autumn before shedding. Flowers creamy white, 5 to 6 mm diameter, spring and early summer, in groups among new season’s leaves at the end of branchlets. Fruit, a brown berry which turns papery when ripe, hangs in clusters from autumn-winter, shed the following spring.
