17 Exceptional Winter Hardy Roses for Cold Climates
Cultivars thriving in subzero lows offer effortless upkeep and vibrant blooms.
Growing roses in areas with frigid winters might seem daunting, but with the right varieties, your garden can flourish with color and fragrance even after temperatures plummet. This comprehensive guide explores winter hardy roses that can withstand intense cold, including those bred to thrive in USDA hardiness zones 2 and 3. Learn how to select, plant, and care for these resilient beauties so you can enjoy their blooms season after seasonâno matter how harsh your winter may be.
Understanding Winter Hardy Roses
True winter hardy roses are bred and selected to endure prolonged cold, heavy frost, and dramatic temperature swings. They exhibit remarkable traits such as:
- Survival in extreme cold: Many withstand temperatures down to -40°F and persist even after deep freezes in zones 2 and 3.
- Reduced maintenance: Less need for winter protection, mulching, and covering than traditional varieties, making them suitable for busy or new gardeners.
- Disease and pest resistance: Many cold hardy varieties show resistance against common rose ailments, further simplifying care.
- Bloom resilience: Ability to flower again and again despite environmental stress.
Most importantly, for gardeners in cold climates, roses grown on their own roots are highly recommended, as grafted varieties can experience winter die-back to the rootstock, especially in extreme chill. Select own-root roses for the best chance of perennial return and vigor.

Tips for Growing Roses in Cold Climates
Even with tough varieties, a few extra precautions ensure survival and maximize performance:
- Buy own-root roses: Avoid grafted plants, as cold may kill the graft and revert the shrub to a less desirable rootstock. Own-root roses reliably return each spring.
- Mulch heavily: Apply 2â4 inches of organic mulch (leaves, bark) around each rose in late fall to help insulate roots and retain soil warmth.
- Plant deeply: Bury the crown 1â2 inches below ground level in very cold zones to prevent freeze damage.
- Water well before freeze: A thorough watering in late fall protects roots from winter dehydration.
- Select a protected site: Where possible, plant roses with windbreaks or near structures/south-facing walls to buffer wind-chill and temperature extremes.
- Minimal pruning: Wait until spring to prune dead wood, as winter dieback can be unpredictable.
- Snow cover is beneficial: Natural insulation from snow helps safeguard stems, buds, and roots.

Frequently Asked Questions (FAQs) About Winter Hardy Roses
Q: Can roses really survive temperatures below -40°F?
A: Yes, many winter hardy varieties, such as Explorer and Parkland roses, are bred for survival in zones 2 and 3, which endure such temperatures. Selecting own-root, cold-bred varieties is crucial for extreme climates.
Q: Are hardy roses also disease resistant?
A: Many shrub and rugosa hybrids are both winter hardy and naturally resistant to diseases like black spot and powdery mildew, reducing the need for sprays and intensive care.
Q: What’s the difference between own-root and grafted roses?
A: Own-root roses are grown from cuttings and will regrow true to type even after severe winter dieback. Grafted roses are grown on the rootstock of a different variety and, if winter kills the top, new growth may not match the original rose. Own-root is strongly recommended for cold climates.
Q: How should I prepare my roses for winter?
A: Mulch deeply around the base, water thoroughly before freeze, and delay spring pruning until new growth appears. In very exposed sites, consider additional protection like burlap wraps.
Q: Can I grow winter hardy roses in containers?
A: It is possible, but more challenging: containers freeze solid and offer less insulation than ground soil. Choose the hardiest possible cultivar, use large insulated pots, and move them to sheltered spots, or overwinter in a cool, protected garage.
