About Holly Companions
The three commonly grown types of holly are American holly (Ilex opaca), English holly (Ilex aquifolium), and Chinese colly (Ilex cornuta). All three are evergreens that will grow in partially shaded locations.
American holly is hardy in zones 5-9, can grow 40-50 feet (12-15 m.) tall and 18-40 feet (6-12 m.) wide. English holly is hardy in zones 3-7 and can grow 15-30 feet (5-9 m.) tall and wide. Chinese holly is hardy in zones 7-9 and grows 8-15 feet (2-5 m.) tall and wide.
A few common holly companions for planting next to the shrubs include boxwood, viburnum, clematis, hydrangea, and rhododendrons.
What Can I Grow Underneath a Holly Bush?
Because holly plants are usually planted small, but eventually grow very large, many gardeners use annual plantings under holly bushes. This prevents having to dig up and move perennials or shrubs, as they holly plants grow larger. Annuals also work well as underplantings for container grown holly shrubs. Some annual holly companions include:
Impatiens Geraniums Torenia Begonia Coleus Hypoestes Inch Plant Lobelia Browallia Pansy Cleome Snapdragons
Planting under holly bushes that are more established is much easier than planting under young holly bushes. Many gardeners even like to limb up large hollies, so that they grow more in the form of a tree. Left natural, holly plants will mature into a classic evergreen conical shape. Some common perennial holly companions are:
Bleeding heart Dianthus Creeping phlox Hosta Periwinkle Sweet woodruff Creeping wintergreen Lamium Cyclamen Daylily Ivy Jacob’s ladder Turtlehead Cranesbill Coral bells Viola Painted ferns Hellebore Epimedium Hepatica Japanese anemone Spiderwort
Low growing shrubs such as gold or blue junipers, cotoneaster, and Moon Shadow euonymus provide a nice contrast to the dark green foliage of holly plants.
