Cold Hardy Hedges

This is a message of hope for anyone living in a cold climate who has given up hope of being able to grow an interesting hedge: you have options! Yes, cherry laurel, yew, and beech are extremely popular in the Zone 5 and up crowd, but don’t think for a moment that there aren’t beautiful choices for the Zone 4 and below folks as well.

These are our favorite cold-hardy hedge varieties:

Hardy to USDA Zone 4 (winter temperatures down to -30°F)

Flame Amur Maple (Acer ginnala ‘Flame’) has lush, green foliage in the spring and summer with vibrant fall colors in hues of yellow, red, and orange (hence its name). It has a quick growth rate and creates a nice privacy screen in summer, while allowing light through its bare branches in the winter. It hedges very well and has a naturally multi-trunked habit. It grows well in full sun to partial shade, is more drought tolerant than most maples, has fair deer-resistance, and does not have any major disease issues. Flame make an excellent privacy hedge for the spring and summer months and adds wonderful seasonal interest to a landscape.

Emerald Green Arborvitae (Thuja occidentalis ‘Smaragd’) is a variety of American Arborvitae that is prized for both its tall, narrow habit and its foliage that stays bright green year-round, with no winter bronzing. It is an extremely popular hedge. One big benefit to using Emerald Green as a hedge is it is very low-maintenance due to its slow and upright growth. Pruning can easily be limited to a light trim once every few years. Its narrow habit also is wonderful in small spaces where a small footprint is desired. It is not deer-resistant, but it has no serious pest or disease issues otherwise.
