Winter Hardiness of Holly

Ilex L.

The winter hardiness of holly is assessed using USDA hardiness zones, which reflect the ability of a particular species to withstand minimum winter temperatures.

In the reference 3 varieties crop Holly, where this is mentioned in the description.

Representatives of the genus Ilex exhibit varying temperature thresholds: Ilex aquifolium is less frost-resistant, whereas the hybrid Ilex × meserveae possesses increased cold hardiness, and species such as Ilex verticillata can tolerate conditions in zones 4–8.

Winter hardiness is a limiting factor that necessitates the selection of wind-protected sites and the implementation of agrotechnical practices such as mulching. Furthermore, plant frost resistance decreases when grown in heavy soils and due to sensitivity to the desiccation of the root system and the aerial parts.
