The different species and cultivars within the Ilex genus vary in size, shape, and leaf coloration, offering a wide range of options for various gardening preferences.

Hollies are generally hardy and adaptable plants, capable of growing in different soil conditions and light exposures. They can be pruned and shaped to suit specific requirements, making them suitable for hedges, borders, or as standalone specimens.
