Holly Nellie R Stevens A fairly compact tree, Ilex x Nellie R Stevens is a large, evergreen, flowering shrub with tree-like habit. The spiny leaves are deep green and glossy. Small, single, white flowers appear in summer, and are great for pollinators. The flowers on female plants are followed by masses of red berries if there is a male plant nearby, which make good winter food for the birds; they are not edible for humans, though. Holly Nellie R. Stevens needs minimal pruning, and dislikes cold, windy positions.
