About the USDA Minnesota Plant Map

While there are many trees, shrubs and flowers that can survive a chilly Minnesota winter, it is useful to know exactly which ones these are before you purchase your plants. The Minnesota USDA plant hardiness map provides information based on average winter low temperature data collected over a 30-year time period.

The new USDA plant hardiness map for 2012 indicates that Minnesota growing zones include 3a and 3b in the northerly regions, 4a in the middle of the state and 4b in the south. An extremely tiny pocket of warmer winter low temperatures exists in the most southerly location and is categorized as 5a. To find your growing zone on the Minnesota planting map, enlarge the map above and look for your general area. On the USDA site, you can search your growing zone by zip code as well.

Your local greenhouse will generally carry plants that are suitable for your growing zone; however, it is always advantageous to check to be sure that they will thrive in your region. Use the plant hardiness zone map information to make this determination.

Although other factors affect the vitality of plants such as humidity, rain, wind, soil type and general plant care, the USDA plant hardiness map provides useful information for novice and experience gardeners alike.
