Summer Bulbs Spring-planted bulbs that bloom during the summer can thrive in most hardiness zones. Sun Perennials Sun perennials are revered for their versatility, attract pollinators to your landscape and produce countless, lovely blooms for years or even decades.
Although factors other than temperature affect a plant's ability to survive in a particular climate, the USDA map is a good starting point when you're trying to decide what to grow, especially if you live in the eastern half of the country.
That's because this area is comparatively flat, so mapping is mostly a matter of drawing lines approximately parallel to the Gulf Coast every miles or so as you move north. The lines tilt northeast as they approach the Eastern Seaboard. They also demarcate the special climates formed by the Great Lakes and by the Appalachian mountain ranges. But in other areas of the country, elevation and precipitation can have more of an effect on plant survival than just temperature.
For annual flowers such as petunias and vegetables such as zucchini, you don't need to pay attention to hardiness zones because these plants usually complete their life cycle seed sprouting to seed producing in a single year. You might see these plants given a zone rating of 0 to indicate they aren't hardy anywhere. But when you're dealing with perennials, vines, shrubs, and trees that typically live for many years, you'll want to find out the coldest temperatures a species is expected to survive and compare that to the zone you're in.
When considering the hardiness zones a particular plant is rated for, think of that information as a guideline, not a guarantee that it will survive in your climate. Only the coldest zone for each listed plant is considered; some of the plants won't thrive in substantially warmer areas.
Always check with the source of your plants for information on whether they are well-suited to your area. Most gardeners aren't dealing with freezing Zone 1 temperatures; only a few parts of Alaska, including cities such as Fairbanks, fall into this zone. However, the northernmost tip of Minnesota also falls in Zone 2b, so if you live in or near Pinecreek, you'll want to look for plants that are hardy in Zone 2.
Most plants native to the U. It's the middle of the road for Zone 6. You can find this zone from Pacific Northwest states , such as Washington and Oregon, and stretching over the middle of the U. Winters only occasionally hit the negatives in this zone. You can find this zone in upper parts of the West Washington, Oregon and down through upper Texas , Oklahoma, and all the way through Virginia and North Carolina.
Things are starting to heat up in Zone 8. The main factor complicating things is that winter temperatures vary widely across North America. In an effort to help gardeners understand which plants are hardy in which areas the USDA developed and published a plant hardiness zone map.
This map was first published in It was updated in and again in These zones are based on the lowest average temperature each area is expected to receive during the winter. The averages used to develop the current map are based on winter temperatures from through The first step in accurately predicting whether a plant will be hardy for you is to find out what your USDA hardiness zone is.
Hardiness Zone Finder to learn what zone you live in or use this map for Canadian zones. Once you know which zone you live in, it is relatively easy to figure out whether a plant will be perennial or annual.
Simply compare your zone to the zone or zones listed on the plant tag or website or within a gardening book. If your zone is equal to or higher than the zone listed for the plant it will be hardy for you, it is perennial in your area. An example, I live in zone 5. If the plant tag says a plant is hardy in zones 5 to 9 the plant will be perennial for me. It would also be perennial in zone 6, 7, 8, and 9.
If I lived in zone 4, then the plant will not be perennial for me, since zone 4 is colder than zone 5. If your zone is lower than the zone listed on the tag then the plant will not be hardy for you, it is an annual in your area.
