About This Collection
Zone 4 covers some of the coldest inhabited regions of the contiguous United States — the Upper Midwest, northern New England, and high-elevation mountain areas where winter temperatures regularly plunge to -20°F or colder. Choosing plants rated for Zone 4 or colder is the single most important decision a northern gardener can make.
The good news: Zone 4 supports a surprisingly wide range of beautiful, tough plants. Native prairie perennials like coneflower, black-eyed Susan, and blazing star evolved in these climates and thrive without coddling. Cold-hardy shrubs like viburnum, spirea, and native dogwood provide four-season structure. And ornamental grasses like Karl Foerster feather reed grass add movement and winter interest even under snow.
The key to Zone 4 success is pairing cold hardiness with your site conditions. A Zone 4 plant in poorly drained clay soil may heave out of the ground during freeze-thaw cycles. PlantWise matches plants not just to your zone but to your sun exposure and soil drainage to give you the most accurate recommendations.

Frequently Asked Questions
What does USDA Zone 4 mean?
Zone 4 means your average annual minimum winter temperature is between -30°F and -20°F (-34°C to -29°C). Plants labeled Zone 4 are rated to survive these temperatures. Zones are based on 30-year averages, so an unusually cold winter can still damage Zone 4 plants.
What states are in Zone 4?
Zone 4 includes most of Minnesota, Wisconsin, Michigan's Upper Peninsula, northern Maine, Vermont, New Hampshire, and high-elevation areas of Colorado, Wyoming, and Montana. Parts of Iowa, South Dakota, and North Dakota also fall in Zone 4.
Can I grow Zone 5 plants in Zone 4?
Sometimes, with protection. Zone 5 plants can survive Zone 4 winters if planted in sheltered microclimates (south-facing walls, protected courtyards), mulched heavily in fall, or wrapped for winter. But for reliable performance, stick to Zone 4 or colder ratings.
What are the best perennials for Zone 4?
Top Zone 4 perennials include purple coneflower (Echinacea), black-eyed Susan (Rudbeckia), blazing star (Liatris), daylilies, hostas, peonies, and ornamental grasses like Karl Foerster. All survive Zone 4 winters without protection.
