USDA Zone Map
What is a plant hardiness zone, and why is it important for you to know yours?
Unfortunately, not every plant is fit to thrive in every zone. Some plants do really well in cold climates, like Canadian roses, while others don't like temps below 40 degrees. Luckily, the USDA has mapped out each zone and categorized them by color, number and letter! When purchasing a perennial such as roses, always be sure to check what the minimum, and in some cases maximum zone your rose can handle. This will save you headaches and grief over dead roses.
Roses love the sun and warm temps, so in most cases we don't post the maximum zone as most are happy up to zone 9b! Also, an additional benefit of own-root roses is that they don't have a graft, so they are much more cold tolerant than their grafted counterparts AND they will never revert to the root stock!
