The best hardy woody plants for a cold climate
If you garden in tough conditions or you live in a colder climate, take inspiration from these hardy woody plants. Words Matthew Biggs
Hostile climates come in many forms. Gardeners may face long snowy winters with a short spring, sub-zero temperatures when the ground freezes for months, exposed headlands or hillsides where the wind chill factor takes its toll, or garden at altitude in northern climes with a growing season measured in a few short weeks.
Nothing quenches our desire to create a garden, whatever the challenges.
The hardiness of woody plants is affected by the moisture levels in the soil, a combination of cold and water-logging proving fatal, with drier soils increasing the chance of survival. Even when cut back to the ground by cold weather, plants often re-grow from the base, particularly when they are mulched to protect them from freezing.
Herbaceous plants, which survive many weeks under a blanket of snow, dislike wet, frozen soil during dormancy, so true cold-climate plants need to be robust and tolerant of the conditions. Careful research and selection and 'putting the 'right plant in the right place' is essential for success.
Here's a list of some hardy woody plants to give you inspiration for your cold climate garden.

Growing information and where to see and buy hardy cold-climate plants
Cultivation
- Create windbreaks on exposed sites to provide sheltered microclimates.
- Plant woody plants on slightly raised mounds in damp soil if you are unsure of their tolerance of waterlogging.
- Plant containerised trees and shrubs in square holes, slightly larger than the pot, then tease out the roots before planting.
- When planting woody plants in clay soils, make the planting hole slightly larger than the rootball – too large and it fills with water and may freeze. In other conditions the hole should be three times the size of the rootball.
- Plant in spring so there is time for plants to become established before the onset of colder weather.
- Protect plants of borderline hardiness by mulching around the roots, covering with horticultural fleece, growing in a sheltered, sunny position or under glass in colder climates, or in containers to be moved indoors in winter.
Hardiness
Wherever possible, we’ve listed the hardiness ratings for plants, which give an indication of the plant’s ability to endure cold conditions. Although several countries have their own plant hardiness ratings, we use the United States Department of Agriculture (USDA) scale, which assigns plants to zones from 1 (very hardy) to 13 (least hardy), and the Royal Horticultural Society (RHS), which runs in the opposite direction from H7 (very hardy) to H1a (least hardy), and tries to reflect the UK’s garden conditions.
You can find out more on both here.
