About this species

Common holly, Ilex aquifolium, is the most widely grown holly in British gardens but there are 500 to 600 other species worldwide. Common holly is a hardy tree or shrub, capable of surviving in most conditions, except where it is extremely wet. Its distinctive spiny leaves deter grazing animals and protect birds from predators as they feed on its bright red berries. It is dioecious, meaning it has separate male and female plants.

The white flowers appear in May and pollination is generally performed by bees and other insects. The berries develop on female plants by late November. 'Holm' is an old name for holly and is seen in place names such as Holmwood and Holmsdale.
