Zone Hardiness Information
Find Roses For Your Climate
Zone 7: 10 to 0 Degrees // Zone 8: 10 to 20 // Zone 9: 20 to 30 // Zone 10: 30 to 40
Alert gardeners will see that plants are well watered before a freeze hits. Roses in pots that are less hardy may be moved into a cold structure that provides some warmth against extreme temperatures, or at least a roof. Move them right back outside as soon as the extreme weather stops, otherwise you will need to observe them carefully all winter. Plants moved indoors must be kept moist. Infestation of spider mites, aphids, or other insects should be prevented by regular application of a systemic pesticide that also contains a fungicide. Moving plants outdoors again is best if just a few plants are involved. Consult successful rose gardeners or organizations in your area for special outdoor techniques used in extreme cold.
Further Notes on Zone Hardiness
The coldest Zone in which it is possible to grow roses at all is Zone 3. Please note that, while the zone ranges given on each individual rose page for that variety are helpful for finding roses appropriate to your area, they are not a guarantee of hardiness.
Occasionally any zone may experience weather outside its normal range. Colder zone gardeners sometimes extend their range of choices by experimenting with various types of winter protection methods and devices and by making good use of any warmer microclimates in their gardens such as a wind protected south wall. For Zones 3-5, we recommend planting into the ground just as soon as freeze danger is past. The good news is that roses on their own roots often will often regenerate if frozen to the ground. Feel free to email us if you have any questions about the hardiness of a rose your are considering. Our guarantees do not apply to winter survival.
We have not included Zone 7 and warmer zones in our drop down searches below because most varieties may be grown in those zones. In Zone 7 the microclimates of the garden need to be taken into consideration in order to grow more tender varieties. Also, when pushing zone limits, one needs to remember that a West Coast Zone usually has less extreme weather than the same East Coast Zone, and, certainly, than the same Central Zone. Other considerations, not covered here, have to do with limitations for extremely southern climates on growing some of the antiques that require a period of winter chill to flower well. If you live in an extreme southern zone and are concerned about having enough chill for flowering, send us an email at firstname.lastname@example.org.
Fall planting is a good thing to do in Zones 7 and warmer. An exception is that we do not recommend planting the Teas, Noisettes, and Chinas after mid summer in Zones 7 and 8a. If you prefer delayed shipping, we will overwinter your order and ship in the spring on the date you specify. Bands and 1 gallon plants can also be potted into 5 gallon or larger pots for overwintering in Zone 7 and up. Colder zones may require taking roses into a cold garage for a brief time during hard freezes.
