The above Connecticut planting zone map is based on the 2023 USDA zone map. In 2023, the plant hardiness zones were changed to better reflect the temperatures in the U.S. over the past few decades. Due to climate change, the temperature zones are higher than they were in the past.
For example, if your zone is 6, you can plant plants that are hardy for zones 6, 5, 4, 3, 2, and 1. Your local nursery will carry plants that are appropriate for your USDA Connecticut growing zone. The plants will be clearly marked with the zone that they belong to. You can buy these plants and know that they will make it over the winter regardless to the temperature and weather conditions.
If you would like to grow something that is not appropriate for your zone, you will need to protect that plant and provide it with appropriate conditions such as the creation of a suitable microclimate.
