Horned Holly Ilex cornuta 'Crimson Fire'

‘Crimson Fire’ is a female cultivar of the Chinese holly (Ilex cornuta) and a member of the holly family (Aquifoliaceae). 

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. A pollinizer is needed to ensure adequate fruit production. 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.

The spiny leaves make this a good choice for a barrier or privacy screen or use as an impenetrable hedge. It can also be planted as a specimen, used in small groups, or planted along a foundation.

Insects, Diseases, and Other Plant Problems:  Holly leaf miner, scale, whitefly, and spider mites are occasional insect pests. Powdery mildew, leaf spot, leaf rot, and tar spot are potential disease problems.  However, it is resistant to phytophthora root rot. Depending on their planting location this shrub can exhibit chlorosis, leaf drop, or leaf scorch from high pH soils. 

The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common diseases and insect pests.
