What does it mean to be cold hardy?
Cold hardy is a term used to describe what is the lowest temperature a plant can withstand in the wintertime. The lower the temperature range, the more cold hardy the plant is.
What is a hardiness zone?
The USDA created specific "zones," allowing individuals to know which plants would be able to survive even the toughest winters in their region! You can search our trees and plants by zone on our website under the Hardiness Zones category tab at the top of the page. Each listing will show its hardiness zone range as well.
If the plant is cold hardy to your zone, no extra means of cold protection are necessary for it in the winter. (Some Japanese maples, particularly those in containers may be an exception.)
