Privet - "Drought-resistant and easy to trim. Fast-growing and long-lived. Glossy foliage frames 3-inch clusters of white flower in May and June, keeps its rich green color late into fall. Bears ebony berries in late fall that cling all winter long. Grows to 10 feet but is easily squared off for a manicured look. Produces a solid screen in a year. Zones 3--7."
