What is a hardiness zone?

A hardiness zone is a geographic area defined by average annual minimum winter temperatures, helping gardeners determine which plants can survive in their region. Developed by the USDA, the 13 numerical zones indicate cold hardiness—for example, a plant "hardy to zone 10" tolerates minimum temperatures of 30 to 40 °F (−1.1 to 4.4 °C).

How to use it when you shop

Set your zone with the Find Your Zone button and every plant on the site shows a green check if it grows in your zone or a red X if it does not. Each product page lists the zones the plant tolerates, and the Shop by Zone menu gathers everything for yours in one place. A plant "hardy to" your zone survives your winters; give it the sun and soil its page describes and it will thrive.
