Holly, Ilex aquifolium
Holly trees are distributed throughout North-West Europe, although dense populations of these trees mainly occur in Britain. The leaves are dark green and leathery, often with spines. The berries are usually red, although sometimes can be found in a yellow form.
Growing and sourcing
