Wavy Leaf LigustrumGrown as a medium sized evergreen for quick screening or hedges. If used as a formal (trimmed) hedge, expect to prune plants twice a year for the neatest look. If used for informal (untrimmed) screening, plants require no pruning whatsoever to keep full and healthy. Leaves cover the plants year round and fragrant white flowers appear in late summer. Wavy Leaf ligustrum grows a bit smaller than Wax Leaf ligustrum and is reportedly a bit more cold hardy.
