Hardiness Zones Explained
If you’re a beginner gardener, some of the lingo associated with planting seeds and bulbs can be like learning a new language. Have you heard of a planting zone? Or a USDA zone? Or a hardiness zone? Maybe you can’t figure out the difference. You aren’t alone, and we’re here to help you make sense of something that sounds much more complicated than it actually is! Refreshing, right?
The U.S. Department of Agriculture (USDA) has conveniently categorized the whole country into 13 sections (or zones) based on weather data. The weather data is important because it lets growers and gardeners know what perennial plants are likely to withstand winter in their area. Notice the word “perennial”? Another bit of lingo! Perennial plants can come back year after year. Conversely, annual plants last only one season. For that reason, planting zones and annuals don’t have much to do with one another!
All about Temperature
If you’re hoping to plant your perennial seeds or bulbs once and see returning blooms each year, you’ll want to select plants based on their ability to survive winter. Every plant we (or anyone) sells has its own hardiness zone, simply meaning it can stand the coldest temperatures of that location. You’ll find that gardeners interchange the word hardiness with growing, planting, or USDA zones—it’s all the same. The low numbers represent the coldest areas of the country, and the high numbers belong to warmer areas. For instance, most Minnesota residents are in zones 3 or 4, while most Florida residents are in zones 9 or 10.
Factors beyond Zone
Of course, you can still plant things that may not survive the winter, or plant things outside your zone! You may take a risk and plant a hyacinth in zone 9, which is not recommended or likely to last past one season, and surprise… it comes back! On the flip side, perhaps you followed every recommendation to the T for planting dahlias, but only a few of your plants returned—it’s rare but can happen. Mother Nature can be a trickster! Other factors like precipitation, snow coverage, humidity, or elevation can even throw a kink into things and influence expected results.
All that is to say that understanding your zone and what to plant there is your best bet for successful veggies or flowers.
