By Augie Alvarez, Horticultural Director — Perennial Gardens Bedford
The deer population in northern Westchester is one of the densest in New York state. Bedford, Pound Ridge, Katonah, and the surrounding communities have deer on essentially every property, every day, multiple times. For homeowners, this is the dominant horticultural constraint — a beautiful landscape that ignores deer pressure becomes a stubbly mess within a season. Working with deer rather than against them is the foundation of successful planting in this region. After three generations of observing what deer will and won't eat across Bedford's landscape, here's a working deer-resistance palette with honest notes on reliability and the design principles that make it work.
The Honest Truth About "Deer-Resistant"
First, a clarification. No plant is completely deer-proof. Under severe pressure — typically late winter when food is scarce — deer will eat almost anything. "Deer-resistant" means deer typically avoid the plant under normal conditions and prefer other food sources when available.
The Cornell Cooperative Extension of Westchester County has documented regional deer feeding patterns for decades. Their resistance ratings are the most reliable reference we have for this region specifically, because deer pressure varies regionally — plants considered deer-resistant in the Pacific Northwest may not hold up in Westchester's density.
Three reliability tiers:
Tier 1: Rarely browsed. Deer actively avoid. Reliable in essentially all Bedford conditions.
Tier 2: Occasionally browsed. Deer may sample but typically move on. Reliable in most conditions; vulnerable during severe winter pressure.
Tier 3: Sometimes browsed. Deer will eat under moderate pressure. Not recommended as foundational palette but can work in protected positions (near house, fenced garden, heavily-trafficked human areas).
Tier 1: The Reliable Backbone
These plants form the structural backbone of deer-resistant gardens in Westchester.
Ornamental Alliums. Alliums (globe masterwort, giganteum, purple sensation, etc.) are essentially never browsed. Spring and early-summer bloom. Great as accent plants.
Lavender (Lavandula). Aromatic oils deer avoid. Zone 6b-7a hardiness requires careful cultivar selection (English lavender 'Hidcote' and 'Munstead' are reliable; French lavender is marginal).
Russian Sage (Perovskia atriplicifolia). Silvery foliage, purple late-summer bloom. Very reliable. Zone-hardy.
Nepeta (catmint). Varieties like Walker's Low and Six Hills Giant. Long bloom, drought-tolerant, deer-resistant.
Salvia nemorosa and related. Deep purple and violet-blue varieties. Deer-resistant, long-blooming.
Iris (bearded and Siberian). Tough, reliable, deer-resistant. Spring bloom.
Peonies (Paeonia). Deer rarely touch peonies. Reliable despite bloom-forward appearance.
Hellebores (Helleborus). Evergreen foliage, late-winter bloom. Deer-avoided.
Epimedium. Understory perennial, great ground cover for dry shade under trees.
Ornamental grasses (most). Deer rarely browse. Miscanthus, Panicum, Calamagrostis, Pennisetum. Winter interest.
Ferns (most). Ostrich fern, lady fern, cinnamon fern. Shade-tolerant, deer-resistant.
Herbs — most varieties. Rosemary, thyme, oregano, sage — aromatic, deer-avoided.
The Missouri Botanical Garden Plant Finder has individual cultivar resistance ratings for each of these.
Tier 2: Occasional Browse Risk
Plants in this tier work well in most conditions but can be vulnerable under heavy late-winter pressure.
Rudbeckia (black-eyed Susan). Usually avoided but sometimes sampled.
Echinacea (coneflower). Similar — usually avoided, occasionally browsed.
Coreopsis. Moderate resistance.
Daylilies (Hemerocallis). Deer favor daylily buds and blooms, but foliage typically less attractive. Bloom can disappear in heavy pressure areas; foliage holds.
Daffodils and narcissus. Bulbs themselves are toxic and deer avoid, but deer sometimes sample fresh shoots in early spring.
Monarda (bee balm). Moderate resistance.
Goldenrod (Solidago). Generally avoided.
Sedum (most varieties). Autumn Joy and related. Usually avoided.
Shasta daisies. Usually avoided.
Joe Pye weed. Usually avoided.
What to Avoid
Plants that deer actively target. Don't use as foundational palette in Bedford or Pound Ridge:
- Hosta (candy for deer)
- Tulips (regular garden tulips; fritillaria is more resistant)
- Pansies and violas (sampled readily)
- Daylily blooms (foliage holds, blooms go)
- Rose buds (especially hybrid tea; old garden roses and rugosa hold better)
- Yew (Taxus) — surprisingly palatable to deer despite toxicity
- Arborvitae (Thuja) — heavily browsed to the deer line
- Apple and fruit tree foliage
Hybrid tea roses are particularly frustrating. Deer eat the new growth and buds preferentially. Alternatives: old garden roses, rugosa roses (Rosa rugosa), and certain shrub roses are more deer-resistant.
Shrubs That Work
Beyond perennials, structural shrubs that deer typically avoid:
Boxwood (Buxus). Reliable. The backbone of deer-resistant formal plantings in Westchester.
Japanese holly (Ilex crenata). Boxwood alternative, also deer-resistant.
Rhododendron (most varieties). Native rhododendron (maximum) strongest; hybrid varieties moderate.
Mountain laurel (Kalmia latifolia). Native, reliable resistance.
Viburnum (most). Spring-blooming varieties generally avoided.
Fothergilla. Native shrub, reliable.
Spirea (most). Fall-blooming spirea reliable; some varieties marginal.
Hydrangea. Varies by type. Smooth hydrangea (arborescens, 'Annabelle') moderately resistant. Paniculata (Limelight) more resistant. Macrophylla (bigleaf) less resistant.
Design Principles for Deer Pressure
Beyond plant selection, design choices matter.
Heavy deer traffic areas need stricter palettes. Properties backing up to preserves, woodland edges, or high-traffic deer corridors need Tier 1 plants only. Less-pressured areas can include some Tier 2.
Fencing is sometimes necessary. For kitchen gardens, cutting gardens, or specific plantings you won't compromise (roses, hostas, specific favorites), deer fencing is the right answer. Fences 8+ feet tall in high-pressure areas. See our landscape cost article for fencing cost context.
Near-house plantings have more flexibility. Deer generally avoid very close to houses, especially where there's lighting, foot traffic, and activity. Plants that would be browsed at the property perimeter may survive near the house.
Group plantings help. Single specimens of vulnerable plants get browsed; large massings can sometimes survive because deer only nibble edges.
Strong-smelling plants deter. Aromatic herbs, alliums, and highly-fragrant perennials near vulnerable plants can reduce browsing.
Seasonal Variation in Deer Pressure
Understanding when deer are hungriest helps plant selection.
Winter (late January-early April). Peak pressure. Food scarce. Deer will eat plants they normally avoid. Evergreen foliage browsing visible on arborvitae, yews, rhododendron shoots.
Spring (April-May). Young growth is most attractive. Emerging perennials, tulip shoots, tree buds all vulnerable. Wet spring can mean abundant forage elsewhere and reduced garden pressure.
Summer (June-August). Relatively lowest garden pressure. Abundant natural forage. Gardens mostly safe.
Fall (September-November). Variable. Deer eat acorns and other mast; garden pressure moderate.
Establishing a Deer-Resistant Garden Over Time
Even with reliable plant selection, new gardens face a specific vulnerability — deer explore new plantings intensely. A plant deer typically avoid becomes temporarily attractive simply because it's new and unfamiliar. First-year plantings often get sampled before deer determine they're not preferred food.
Mitigations for the establishment period:
Temporary deer repellent. Liquid Fence or similar applied weekly during establishment reduces early-season browsing while deer learn the garden's palette.
Temporary fencing. Deer netting or temporary fence around new plantings for the first year lets plants establish without pressure.
Dense planting. Install enough plants that deer browsing on outer edges doesn't decimate the planting.
Monitor and replace promptly. First-year browsed plants sometimes recover; sometimes they don't. Replacement at fall planting time rather than leaving gaps keeps the planting scheme intact.
By year two or three, plants that weren't going to survive deer pressure have been removed and replaced; plants that do survive become reliable long-term.
Integration with Broader Landscape
Deer-resistant design integrates with the broader landscape approach. See our four-season estate garden guide for how structural plantings (evergreens, ornamental grasses) anchor year-round composition while being deer-avoided.
Our garden center stocks most of the deer-resistant perennials referenced above, and our horticultural team can help match specific varieties to your property's deer pressure level.
Frequently Asked Questions
Does Bedford really have worse deer than other parts of Westchester?
Bedford, Pound Ridge, and neighboring towns have among the highest deer densities in the Northeast. Southern Westchester has significant deer, but the density in the northern towns is particularly high. Plan palette accordingly.
Can deer repellents work?
Temporarily, yes. Products like Liquid Fence, Deer Out, and similar work short-term but require reapplication after rain and weeks of use. They're useful for specific prized plantings during peak pressure periods but aren't a substitute for deer-resistant plant selection as the foundation.
What about deer-resistant lawn alternatives?
Clover and various native ground covers perform well. Standard turf grass is not particularly attractive to deer (they prefer richer browse). Lawn pressure from deer is usually minimal.
Can Perennial Gardens help design a deer-resistant garden for my property?
Yes. Our garden center and landscape practice both specialize in regionally-appropriate design, and deer management is a foundational part of every northern Westchester planting plan. Reach us through the contact page for a consultation.
