Minnesota’s USDA hardiness range runs from 3a to 5a, a spread wide enough that a plant thriving in the Twin Cities can freeze out entirely near the Canadian border. Of the 65 landscape plants this site tracks, 30 survive statewide, 31 depend on which end of that range you’re in, and 4 fail everywhere in Minnesota regardless of zip code.
What will not survive a winter in Minnesota
Four plants documented on this site are not hardy anywhere within Minnesota’s 3a-5a range. These aren’t marginal calls or matters of microclimate luck. Their hardiness ranges simply don’t reach as far north as Minnesota’s coldest zone requires, and in at least one case, the problem runs the other direction entirely.
| Plant | Its hardiness range | Where the mismatch is |
|---|---|---|
| Ficus carica (fig) | Warmer zones only | Too cold |
| Hydrangea macrophylla (bigleaf hydrangea) | Warmer zones only | Too cold |
| Lagerstroemia indica (crape myrtle) | Warmer zones only | Too cold |
| Magnolia grandiflora (southern magnolia) | Warmer zones only | Too cold |
All four fail on the cold side, which makes sense given Minnesota sits at the northern edge of what USDA zones cover in the continental U.S. There’s an important distinction buried in that word “hardy,” though. A hardiness rating measures survival, not comfort. A plant listed as hardy in a given zone can still struggle there if that zone represents the outer edge of its heat tolerance rather than its cold tolerance. So even among the 30 plants that will survive across all of Minnesota, a few are working near one boundary of their range rather than sitting comfortably in the middle of it. Survival and thriving are not the same promise.
Worth noting: these four are absences from what this site documents, not a claim that nothing in these genera can grow in Minnesota. Gardeners sometimes find zone-pushing cultivars or use structures like heavy mulching and wall protection to nudge a marginal plant through. But as a straightforward hardiness match, these four don’t work anywhere in the state’s range.
The plants that work in part of the state and not the rest
This is where a statewide answer breaks down, because Minnesota isn’t one zone, it’s three (3a, 3b/4a, and up through 5a). Thirty-one of the 65 plants this site documents are hardy in only part of that range, which means the honest answer to “will this grow here” depends entirely on which part of Minnesota “here” means.
Grouping by where the failure happens: some plants struggle in the very coldest pockets of the state (zones 3a and 3b), some fail across a broader stretch reaching into 4a and 4b as well, and none of the 31 fail only at Minnesota’s mild end. That’s consistent with what you’d expect: Minnesota’s range extends into genuinely severe cold in its northern reaches, and plenty of otherwise-versatile species simply can’t take it.
| Plant | Its hardiness range | Zones of Minnesota it does not cover |
|---|---|---|
| Betula nigra (river birch) | Broad | 3a, 3b |
| Cercis canadensis (redbud) | Broad | 3a, 3b |
| Cornus florida (flowering dogwood) | Narrower toward cold | 3a, 3b, 4a, 4b |
| Liquidambar styraciflua (sweetgum) | Narrower toward cold | 3a, 3b, 4a, 4b |
| Nyssa sylvatica (black tupelo) | Broad | 3a, 3b |
| Platanus occidentalis (sycamore) | Broad | 3a, 3b |
| Quercus rubra (red oak) | Broad | 3a, 3b |
| Buxus sempervirens (boxwood) | Narrower toward cold | 3a, 3b, 4a, 4b |
| Fothergilla gardenii | Narrower toward cold | 3a, 3b, 4a, 4b |
| Ilex glabra (inkberry) | Broad | 3a, 3b |
| Itea virginica (sweetspire) | Narrower toward cold | 3a, 3b, 4a, 4b |
| Kalmia latifolia (mountain laurel) | Broad | 3a, 3b |
| Weigela florida | Broad | 3a, 3b |
| Lavandula angustifolia (lavender) | Narrower toward cold | 3a, 3b, 4a, 4b |
| Amsonia hubrichtii | Narrower toward cold | 3a, 3b, 4a, 4b |
| Monarda didyma (bee balm) | Broad | 3a, 3b |
| Phlox paniculata | Broad | 3a, 3b |
| Salvia nemorosa | Broad | 3a, 3b |
| Heuchera americana | Broad | 3a, 3b |
| Hylotelephium spectabile (sedum) | Broad | 3a, 3b |
A shorter tail of fruiting plants (Asimina triloba, Diospyros virginiana, Fragaria varieties, Morus rubra, Prunus domestica and persica, Pyrus communis, Rubus species, Sambucus canadensis) follows the same pattern: some limited to 3a/3b, others excluded from the 4a-4b band as well. The list above names the specific zones each plant fails in; treat that as the operative detail rather than a blanket yes or no.
Finding out which of those zones covers your own address means checking Minnesota’s county-level hardiness picture, which this site’s insulation and climate page breaks down in more detail than the statewide range given here.
The soil and the summer they will be planted into
Minnesota’s official state soil, the Lester series, is a well-drained Alfisol, a forest soil of moderate fertility with a surface pH around 6.6 and a texture that runs 39 percent sand, 24 percent clay, 37 percent silt. That composition puts it in loam-to-silt territory: not so sandy that water runs straight through, not so clay-heavy that it holds water for days. For a newly planted tree or shrub, that drainage matters more than almost anything else in the ground. Winter wet, not winter cold, is what kills more woody perennials than people expect. Roots sitting in saturated soil through a freeze-thaw cycle suffocate or heave, and a well-drained soil like Lester series conditions sidesteps a lot of that risk.
That’s the state soil, though, not necessarily the soil in any particular yard. Minnesota spans hundreds of soil series, and anything from a river bottom to a subdivision lot scraped and refilled during construction can look nothing like the Lester profile. A soil test remains the only way to know what’s actually under a given planting site, particularly for organic matter and pH, both of which shift the calculus on which plants settle in easily.
What summer rainfall adds to the picture
Minnesota sees about 13.0 inches of rain across June, July and August, with July running driest at 4.06 inches against June’s 4.58 and August’s 4.34. Those numbers describe precipitation, not humidity and not a watering schedule. What they mean for a given planting depends on the soil underneath. The same 4 inches of July rain soaks in and stays accessible on Lester-series loam in a way it wouldn’t on straight sand, where water passes through within a day, or on heavy clay, where it can sit long enough to threaten roots that don’t like wet feet. A rain gauge on the actual planting site, tracked against how quickly the ground dries afterward, tells a gardener more than the regional average ever will.
When to plant, here
Minnesota’s last spring frost falls between April 17 and April 30, and the first fall frost arrives between October 11 and October 23, according to NOAA’s 1991-2020 normals for the reference station. Those two windows set up the two practical planting seasons, and the reasoning behind each matters more than memorizing a calendar date.
A woody plant put in the ground needs time to grow roots before it’s asked to do anything else, whether that’s push out leaves in spring or survive a hard freeze in fall. Spring planting gives roots a full growing season to establish before winter arrives, but it also means competing with a plant’s own energy going toward leaf-out, and a late cold snap can still catch new growth off guard. Fall planting lets a plant settle into cooling, moister soil with less demand on it, but the clock is shorter, especially the closer a site sits to Minnesota’s cold end.
| Window | What it suits | Main risk |
|---|---|---|
| Spring (after roughly April 17-30) | Most Trees, Shrubs and Perennials; especially anything marginal for the local zone | Late frost damaging new growth; competition between root and leaf development |
| Fall (before roughly October 11-23) | Establishing woody plants that benefit from cool-season root growth | Not enough time before hard freeze, particularly in the coldest bands of Minnesota’s range |
In the northern reaches of Minnesota’s range, the fall window is meaningfully tighter than in the south, since frost arrives earlier there and the gap between planting and hard freeze compresses further. These dates are also averages at one reference station, not a guarantee for any specific week or town. And whatever a plant’s mature drought tolerance rating says, it doesn’t apply the first season. Newly planted trees and shrubs need consistent watering while roots establish, regardless of how drought-tolerant the species becomes once settled in.
Where to read about each one
Among the plants that suit all of Minnesota’s range, the tree list includes Acer rubrum, Acer saccharum, Amelanchier canadensis, Carpinus caroliniana, Ginkgo biloba, Juniperus virginiana, Picea abies, Pinus strobus, Quercus alba, Thuja occidentalis and Tilia americana. Shrubs that hold up statewide include Aronia arbutifolia, Clethra alnifolia, Hydrangea paniculata, Ilex verticillata, Physocarpus opulifolius, Spiraea japonica, Syringa vulgaris and Viburnum dentatum. On the perennial and fruiting side, Achillea millefolium, Asclepias tuberosa, Baptisia australis, Echinacea purpurea, Iris sibirica, Rudbeckia fulgida, Aronia melanocarpa, Prunus avium, Vaccinium angustifolium and Vaccinium corymbosum all fit the full range as well.
The hardiness figures behind every plant named on this page come from the North Carolina Extension Gardener Plant Toolbox, a university extension database, crossed against Minnesota’s own 3a-5a range. These are hardiness ranges specifically, describing cold survival, and they’re a separate measure entirely from the adaptation zones this site uses elsewhere for apple varieties, which come from a different fruit-variety table and answer a different question about fruiting performance rather than winter survival.
