Maine carries some of the heaviest deer pressure in New England, and gardeners from Kittery to Bangor already know the frustration of watching a bed of expensive perennials get browsed to stubs overnight. No plant is completely deer-proof — a hungry deer in a hard winter will sample almost anything — but plenty of Maine natives are reliably low on their preference list, thanks to aromatic oils, milky or bitter sap, fuzzy foliage, or just tough, unpalatable texture. Building a garden around these species, all pulled from Maine's verified list of native plants, will save you a lot of repellent spray and frustration.
Aromatic Perennials Deer Learn to Skip
Strong-scented foliage is one of the most reliable deer deterrents, and Maine has several native options that lean on this strategy. Anise Hyssop (Agastache foeniculum) has licorice-scented leaves that deer largely ignore, paired with long-blooming lavender-blue flower spikes that pollinators love. Common Yarrow (Achillea millefolium) works the same way with ferny, pungent foliage and flat white flower clusters, and it tolerates the poor, dry soil found on a lot of Maine properties. Wild Bergamot (Monarda fistulosa) and Scarlet Beebalm (Monarda didyma) are both minty-scented bee balms that deer rarely bother with — give them decent air circulation to avoid the powdery mildew that's a common complaint with monarda in humid Maine summers. Short-Toothed Mountain Mint (Pycnanthemum muticum) may be the most aromatic plant on this entire list; crush a leaf and you'll understand immediately why deer move past it, while pollinators can't get enough of its silvery summer bracts.
Milkweeds and Other Plants With Bitter, Milky Sap
Common Milkweed (Asclepias syriaca), Swamp Milkweed (Asclepias incarnata), and Butterfly Weed (Asclepias tuberosa) all contain bitter compounds in their sap that make them unappealing to deer, even though monarch caterpillars have evolved specifically to eat them without harm. Common Milkweed spreads by rhizome and does best given room to roam in a sunny, meadow-style planting; Swamp Milkweed prefers consistently moist soil and suits a low spot or rain garden; Butterfly Weed wants the driest, sandiest soil of the three and resents being moved once established, so choose its permanent spot carefully the first time.
Sturdy Perennials for Borders and Meadows
Beyond the aromatic and toxic-sap categories, a handful of tough, fuzzy, or bristly natives round out a deer-resistant border. Black-Eyed Susan (Rudbeckia hirta) and Purple Coneflower (Echinacea purpurea) both have coarse, bristly foliage and stems that deer tend to pass over in favor of softer options, and both leave seed heads that finches and other birds work over all winter — worth a look at our guide to Maine's backyard birds if you want to plant specifically with them in mind. Showy Goldenrod (Solidago speciosa) is a well-behaved goldenrod that doesn't run as aggressively as some of its roadside cousins, blooms late into fall when little else is going, and draws migrating pollinators without the hay-fever reputation goldenrod unfairly carries (that's ragweed's fault, not goldenrod's). Culver's Root (Veronicastrum virginicum) offers tall white candelabra spikes and whorled foliage deer rarely touch, Foxglove Beardtongue (Penstemon digitalis) has slightly bitter leaves that keep browsing to a minimum, and Blue Vervain (Verbena hastata) holds up well in the damp, part-sun spots where deer traffic is often heaviest.
Shrubs Deer Tend to Leave Alone
For structure and screening, several native shrubs hold up better against deer than the boxwood and arborvitae typically sold for the same purpose. Ninebark (Physocarpus opulifolius) is about as tough as a native shrub gets, tolerating poor soil, wet spots, and hard pruning while rarely showing browse damage. Fragrant Sumac (Rhus aromatica) has aromatic foliage similar to the perennials above, stays low and spreading, and works well for stabilizing a bank or slope. Inkberry Holly (Ilex glabra) offers a broadleaf evergreen alternative to boxwood, with leathery leaves that are a low priority for deer, and New Jersey Tea (Ceanothus americanus) is a compact, drought-tolerant shrub deer generally skip in favor of softer plants nearby. On sandy or rocky sites, Bearberry (Arctostaphylos uva-ursi) forms a tough, low evergreen groundcover mat that deer rarely bother with, and it holds up on coastal ledge and dune sites where almost nothing else will grow.
Grasses and Ferns as a Deer-Resistant Backbone
Ornamental grasses are consistently near the bottom of a deer's preference list, and Maine natives are no exception:
- Little Bluestem (Schizachyrium scoparium) — fine-textured, reddish-bronze fall color, tolerates poor dry soil
- Big Bluestem (Andropogon gerardii) — tall and upright, good for a meadow backdrop
- Switchgrass (Panicum virgatum) — airy seed heads, tolerates wetter soil than most grasses on this list
- Indian Grass (Sorghastrum nutans) — golden fall color, pairs well with late-blooming perennials
- Prairie Dropseed (Sporobolus heterolepis) — fine, fountain-like habit, one of the tidiest native grasses for a border
All five provide structure, movement, and winter interest that deer largely walk past, making them an ideal backbone for a meadow-style planting mixed with the perennials above. Christmas Fern (Polystichum acrostichoides) and Cinnamon Fern (Osmundastrum cinnamomeum) offer the same deer resistance in shadier spots, thanks to a texture deer simply don't find appealing.
Combine several categories rather than relying on just one — a border of aromatic perennials backed by deer-resistant shrubs and grasses is far more resilient than a single deer-proof species surrounded by vulnerable plants, since deer will still browse a tempting neighbor right up to the edge of anything they dislike.
