Native Ranges & Hardiness Zones

  • Plants will grow outside of their native range, as long as the growing conditions and the temperatures are aligned with the plant requirements.
  • Hardiness zones and native ranges are two separate methods, and both of them speak to the temperate conditions of a location. It's not necesssary to use them both, you may use either one or the other.
  • Whichever of these methods you use, the growing conditions are of primary importance.

Native Plant Ranges

A plant’s ‘native range’ is the region where a plant species is known to be native. To find plants that are native to your region, select “Native Range” as a filter option when browsing for plants on our website. Additionally, each plant page on our website includes a "Range Map" which shows detailed information about the distribution of the plant (within the continental U.S.). These maps are an excellent reference for restoration landscaping. For gardening – as a temperate zone indicator – it is not necessary to acheive pinpoint accuracy. Native plants will and do grow outside of these boundaries.


Hardiness Zones

Many gardeners are familiar with the hardiness zones model, and we've include "Zones" as a filtering option on our website. The USDA hardiness zones represent geographical areas of the United States defined by the average minimum winter temperatures.

In order to get the full benefits, beauty and pleasure from your native plants, choose plants that are well suited to the growing conditions at your location. Plants that are a good fit for the site conditions will create a sustainable garden that flourishes without additional resources, for years to come.
