Another JC Raulston Arboretum selection from the same Ilex verticillata and Ilex serrata cross that produced Carolina Cardinal, Carolina Sentinel takes a dramatically different shape. Where Cardinal spreads low, Sentinel rises narrow and columnar, capable of reaching eight to twenty feet in height with a density of deep green, nearly blue-green foliage that makes it one of the more striking evergreen verticals available for southern gardens. Female plants carry a heavy crop of red berries from fall into winter, the fruit persisting against the dark leaves long enough to provide genuine winter interest.

Its cultural adaptability is considerable. The plant tolerates heat and humidity, becomes drought tolerant once established, and accepts most soils except waterlogged ones. The spiny leaves make it a serious barrier hedge, particularly effective in narrow spaces where a broader plant would not fit. Pruning in late winter keeps its size in check without disrupting the following season's fruit. One practical note: mature plants resent root disturbance, so choosing its permanent position thoughtfully at planting saves trouble later. A site with some winter protection during the first year or two gives it the best start in colder reaches of its range.
