About PlantGuideOnline.com
We launched in 2011 as a way to help gardeners, landscapers, and horticulturists easily access growing zone data by town or zip code.
Our site combines databases from the United States Department of Agriculture (USDA), meteorologists, and top universities in order to show the USDA growing zones broken down with individual planting recommendations for every town and zip code in the United States. It wasn't easy (that's over 100k towns!) but we're proud to be one of the oldest and biggest plant search tools online.
Since the early days of only providing USDA growing zone data, we've grown our site to offer even more help in choosing the best plants to grow for your climate. In addition to looking up your growing zone, you can now find vegetables, fruits, flowers, trees and more individually selected for your region. Find your town, learn your growing zone, and choose the right plants for your gardening or landscaping projects, knowing the data is on your side.
Our data is up to date through November 2023 when the USDA put out the updated version of their plant hardiness map. Based on U.S. weather data from 1991 to 2020, the map is split into 13 zones. Each zone represents a 10 degree Fahrenheit difference in the average annual low temperature.
