Holly
Most hollies have glossy, prickly foliage. The plants are dioecious, meaning there are both male and female plants. For female plants to produce their brightly colored berries, a compatible male plant must be planted nearby. There are evergreen and deciduous hollies; evergreen types tend to be less hardy than deciduous ones. Size ranges from 6 to 40 feet tall and wide, depending on the type. Evergreen hollies can be sheared into formal hedges, and holly berries attract birds.
