THE BEST PLANTS FOR ZONE 3
Zone 3Change my Zone
If you live in Zone 3, then you should know it is the coldest and smallest of the zones, with a frost-free growing season lasting only from early June until early September. U.S. cities within this sparsely populated plant hardiness zone include Stanley, Idaho, and International Falls, Minnesota. Asters, astilbe, crocus, daffodils, delphiniums, hostas, hydrangeas, peonies, phlox, sedum and tulips are among the Zone 3 perennials and bulbs we recommend.
Don't forget that your Zone 3 garden probably has several microclimates within it, each of which is best suited for different plant types and varieties. Take some time to determine which microclimates your yard or garden may have, whether it's an open area of your backyard that's always in direct sunlight, a shaded spot beneath a big tree, a rock-covered hill, or a marshland. With a little bit of practice, choosing the best plants for Zone 3 that will also thrive in your garden's specific microclimates will soon become second nature.

Top Summer Bulbs for Zone 3Shop all »
Spring-planted bulbs that bloom during the summer can thrive in most hardiness zones. What's more, they produce some of the most vibrant colours of the year. Varieties include dahlias, lilies, gladiolus, caladium, cannas, and begonias. In cooler regions, try planting summer bulbs outdoors in pots before transferring them--once the soil is warm enough--to your garden bed or border. Most can go in the ground once the possibility of frost has passed.

Top Sun Perennials for Zone 3Shop all »
Sun perennials are revered for their versatility, attract pollinators to your landscape and produce countless, lovely blooms for years or even decades. No wonder these are some of the world's most popular flowers! Sun-loving perennials include roses, peonies, irises, daylilies, hibiscus, coneflowers and asters. These varieties perform best when receiving about 6-8 hours of direct sunlight per day. Without it, the plants grow poorly, and their blooms, if any emerge, are drab and lifeless.

Top Shade Perennials for Zone 3Shop all »
Some gardeners don't even try to grow anything in the shaded areas of their gardens or yards. That's a shame, because some incredible plant varieties--including those that yield many delicate, colourful blooms--fare well when grown within dark shadows. We recommend such shade seekers as hellebores, hostas, astilbe, bleeding hearts, toad lilies and ferns. Poor soil can hinder a shade perennial garden more than a lack of sunlight, so be sure to add plenty of organic matter when preparing a new one. Avoid damaging roots when planting Shade Perennials near trees.

Largely because they signal the welcome return of warmer weather, spring blooms not only possess considerable natural beauty, but they also tend to occupy a special place in our hearts. Fall-planted bulbs include tulips, daffodils, hyacinths, alliums and crocus, a small plant that can flower even before the end of winter. Grow them in rich, well-drained soil that will receive plenty of sunlight. Remove weeds, loosen soil and add compost before planting.

The U.S. Department of Agriculture's Plant Hardiness Zone Map, which divides the continental U.S. into eight gardening zones based on wintertime minimum temperature averages, can help you select plants that have the best chance of flourishing where you live. Each of our product pages lists the hardiness zones in which that particular plant is best suited for growing. Take the time to learn your location on the garden zone map. Don't wait until the next planting season begins to ask yourself, "What is my gardening zone?" or "What gardening zone am I in?" We can't emphasize this point enough: It's crucial for you to know your zone before choosing your plants. Selecting the right plants for your zone helps ensure a better performing and more attractive garden. As you become a more seasoned gardener and come to be more familiar with the advantages--and the limitations--of your growing season, you'll learn which of your favourite plants you can grow most successfully.
