Zone 1 plants are tough, vigorous, and adaptable to cold extremes. Surprisingly, many of these are also xeriscape plants with high drought tolerance. The Yukon, Siberia and parts of Alaska are representatives of this harsh planting zone. Gardening in zone 1 isn’t for the faint of heart. Planting choices must be acclimated to the tundra and harsh conditions. Read on for a list of cold hardy plants that can withstand temperatures of – 50 degrees Fahrenheit (-45 C.) in winter.

Zone 1 Perennial Plants

Even extreme northern gardens should have some perennials and annuals. Plants for extreme cold are rare, but the first choices to look at are the native specimens.

Adaptable plants for extreme cold regions will do best if allowed to adjust to the harsh conditions. They may also require a bit more babying to thrive, such as heavy winter mulch, supplemental water, and a sheltered location.

Gardening in zone 1 doesn’t have to be limited by the weather patterns, either. Place your selections in containers so that when a killing frost or other weather event threatens, you can whisk your babies indoors. Some non-native but hardy specimens for sound and movement in the landscape might be:

Keep in mind that many of the northernmost territories are also wild, meaning deer, moose, rabbits and other wildlife are always ready to munch on your plants. Use fencing to limit their browsing in the garden and protect your new plants.
