Ilex x 'Carolina Sentinel'

The Carolina Sentinel Holly is an Ilex cultivar resulting from a cross between I. verticillata and I. serrata. It has a narrow, dense and columnar form. For comparison, the form is more narrow and dense than the 'Nellie R. Stevens' cultivar. The Carolina Sentinel Holly is an evergreen shrub or small tree with leaves that are a deep green, almost a blue-green and inconspicuous white flowers. Female plants produce a heavy crop of red berries in the fall through the winter. The plant is dioecious (meaning individual flowers are either male or female, but only one sex is found on any one plant so both male and female plants must be grown if fruit is required). It is excellent for hedges, particularly in narrow spaces. It tolerates pruning and, in the landscape, can be grown as a hedge or trained to be a small tree. It is a JC Raulston Arboretum Selection.

This holly is tolerant of most soils except poorly-drained ones and can be grown in full to partial sun. It is tolerant of heat and humidity and is drought tolerant once established, making it a good choice for the south. Prune in the late winter to control its size if needed. The fruit and evergreen leaves make for winter interest in the landscape. The spiny leaves make this a good choice for a barrier as an impenetrable hedge. Mature plants do not tolerate root disturbance, so it is best to site the plant in its permanent position, preferably one that provides winter protection for the first year or two.
