Everyone is familiar with our common holly, Ilex aquifolium, with its glossy evergreen leaves and red berries. But there are lots of other varieties to grow, some with attractive foliage and berries that range in colour from orange to purple.Hollies are generally male or female, so check before you buy. If you want berries on a female plant, you will need to plant a male nearby. Some cultivar names can be confusing: for example, Ilex aquifolium ‘Golden Queen’ is male, while Ilex x altaclerensis ‘Golden King’ is female.
