Deer Resistant Annuals

How deer choose which annuals to eat

Deer select food based on palatability, scent, texture, and how hungry they are. An annual that deer ignore in a rural garden with 2 deer per square mile will get eaten in a suburban yard where 20 deer compete for food. Deer resistance is a spectrum, not a guarantee.

The Rutgers New Jersey Agricultural Experiment Station deer damage rating system is the most widely referenced in the US. It rates plants from A (Rarely Damaged) through D (Frequently Severely Damaged). The ratings come from observed damage across thousands of US garden sites — not manufacturer claims or anecdotal reports.

Three traits make an annual flower reliably deer-resistant:

Strong scent. Deer have a sense of smell estimated at 1,000 times more sensitive than humans. They associate strong fragrance with potential toxicity or unpalatability. This explains why marigolds, snapdragons, and salvias hold up better than most other annuals.

Hairy or rough texture. Deer prefer smooth, tender foliage. Snapdragons, dusty miller, and zinnias all have textured leaves that deer find less appealing.

Toxic compounds. Some annuals contain alkaloids or other compounds that deer have learned to avoid. Snapdragons and some salvias fall into this category.

Rutgers A-rated annuals: rarely damaged in any US zone

These annual flowers are rated A by Rutgers — deer avoid them consistently even in high-density suburban areas where food pressure is severe.

Snapdragons are particularly valuable because they perform in cool spring weather — the highest deer-pressure period of the year. Plant them in early April in Zones 6–7, late March in Zones 8–9, and after last frost in Zones 3–5. They provide color when deer are hungriest and almost nothing in the annual world is reliably resistant.

Dusty miller is grown primarily for silvery foliage, not flowers. It works as a reliable anchor in mixed annual beds and pairs with any flower color. Its woolly texture is the main deterrent — deer consistently avoid touching it.

For a full-season planting strategy using deer-resistant annuals alongside perennials, see our Deer Resistant Flowers guide, which covers the Rutgers rating system in detail and includes the best plants for building a complete deer-resistant border.

Best deer-resistant annuals for summer color

Summer is the primary annual planting season for most US gardens. These are the warm-season annuals with the best documented deer resistance.

Marigolds (Tagetes): Rated B by Rutgers — “Seldom Severely Damaged.” Deer avoid marigolds in most seasons because of their strong pungent scent. Young transplants in early May are the most vulnerable — deer bite them before the plant is fully established and scent is at maximum. Established marigolds (6+ weeks in the ground) rarely get touched. See our full Marigolds: Care and Growing Guide for varieties and companion planting uses.

Zinnias (Zinnia elegans): Rated B–C depending on zone and pressure. Rough, hairy foliage deters deer, but hungry deer will eat them. In moderate-pressure areas (Midwest suburbs, mountain west), zinnias generally hold up. In high-pressure areas (suburban Northeast, Pacific Northwest suburbs), protect transplants with repellent spray. See our Zinnias: Care and Growing Guide for growing details.

Vinca (Catharanthus roseus): The heat-loving summer annual — not the groundcover vinca vine — is moderately to strongly deer-resistant. Its slightly toxic properties make deer avoid it in most conditions. It tolerates southern heat better than most deer-resistant annuals. See our Vinca Flower guide for the full picture.

Lantana: Strongly deer-resistant due to strong fragrance and mildly toxic berries. Works as a spreading groundcover annual in Zones 9–11 (where it is perennial) and a full-sun annual in Zones 3–8. Lantana: Care and Growing Guide covers varieties and uses.

Cleome (spider flower): Deer strongly avoid the slightly spiny stems and pungent foliage. It self-seeds readily — plant it once and you may never need to replant. Grows 4–6 feet tall, so it works at the back of annual borders where deer pressure from neighboring properties is highest.

Deer-resistant annuals for shade

Shade options are more limited. Most strongly scented, rough-textured annuals prefer full sun.

Wax begonias are the most reliable shade annual for deer country. Their slightly waxy, bitter foliage holds up well in part-shade and full-shade beds. In my Nashville test beds, wax begonias performed better than standard impatiens in every single test year. They also tolerate more sun than most begonias — part shade is ideal, but they survive full morning sun if watered consistently. See our Begonia guide for varieties best suited to deer-heavy gardens.

Caladiums are sometimes listed as deer-resistant. The data is mixed. Deer eat caladiums in some gardens and ignore them in others. The calcium oxalate crystals in caladium leaves can cause irritation — deer learn to avoid plants that cause mouth discomfort. But in high-pressure areas, hungry deer eat them anyway. Do not count on caladiums as reliable deer protection.

Coleus is moderately resistant. The strong, slightly bitter flavor deters deer in many conditions. New Guinea impatiens perform better than standard impatiens but are still far from reliable. See our Coleus: Care and Growing Guide for varieties.

Annuals that are NOT deer-resistant despite common claims

Garden centers and seed catalogs routinely exaggerate deer resistance. These annuals are frequently marketed as resistant but consistently get eaten in US gardens:

Standard impatiens (Impatiens walleriana): Deer eat these readily. They are tender, flavorful, and easy to access. If you have deer pressure and want color in shady spots, replace standard impatiens with wax begonias.

Petunias: Deer eat petunias. The sticky, somewhat hairy foliage does not deter deer in high-pressure areas. They are moderately resistant in rural low-pressure areas but unreliable in suburban gardens.

Pansies and violas: Deer eat pansies — a particular problem in spring when pansies are planted and deer pressure peaks simultaneously. Protect spring pansies with repellent spray for the first 3–4 weeks.

Begonias (tuberous varieties): Unlike wax begonias, tuberous begonias get eaten more readily. The large, soft, flavorful leaves are palatable to deer. Standard tuberous begonias should be treated as not resistant.

New Guinea impatiens: Slightly more resistant than standard impatiens, but eaten regularly in high-pressure areas. They are a marginal upgrade, not a reliable solution.

How to protect deer-resistant annuals that still get browsed

Even highly resistant annuals occasionally get browsed, especially in spring when deer populations peak and food is scarce after winter.

Repellent sprays that perform best in US university trials contain putrescent egg solids or predator urine. Plantskydd (blood-meal based) consistently outperforms oil-based repellents in cold-weather trials — important for protecting early spring pansies and snapdragons before deer get accustomed to the planting.

The single most cost-effective protection: use a temporary wire fence around new transplants for the first 4 weeks after planting. This covers the highest-risk period when plants are small, tender, and not yet fully established. Once plants are 8–12 inches tall and growing vigorously, most deer-resistant varieties hold up without additional intervention.

Deer pressure by season: when to protect annuals

Spring (March–May) is when annual plantings face the most risk. Deer are at peak hunger after winter. New transplants are small, tender, and easy to reach. Applying repellent spray at planting time — not after damage occurs — is the most effective timing.

In the Southeast and mild Pacific Coast zones, cool-season annuals like pansies and snapdragons are planted in fall for winter color. These face high deer pressure in November and December. Apply repellent spray when planting and reapply monthly through winter.

Combining deer-resistant annuals with perennials

The most effective deer-resistant garden strategy in the US is a mixed border — reliable deer-resistant perennials as the backbone, with resistant annuals filling color gaps through the season.

Backbone perennials with strong deer resistance: lavender, catmint, Russian sage, salvia nemorosa, ornamental grasses. See our Deer Resistant Perennials guide for a full perennial selection list with Rutgers ratings.

Annual color layers: snapdragons in spring, marigolds and zinnias through summer, dusty miller as a constant foliage anchor. This palette gives color from April through October without replanting resistant species.

For attracting pollinators while keeping deer out, the overlap between deer-resistant and pollinator-friendly annuals is strong. Marigolds, zinnias, and salvias are all strong pollinator plants. See our Attract Pollinators to Your Garden guide for combining deer resistance with wildlife habitat goals.

The Rutgers deer-resistance database, available through the New Jersey Agricultural Experiment Station, is the most authoritative free resource for US gardeners evaluating specific plant species. It covers hundreds of annuals and perennials with damage ratings from real garden observations across New Jersey and surrounding states — the highest deer-pressure region in the US.

Regional notes on deer and annuals

Suburban Northeast and Mid-Atlantic (Virginia to Maine): Highest deer pressure in the US. Use A-rated annuals only in open beds. Protect everything else with spray or fencing. Even marigolds get hit in this zone in spring.

Pacific Northwest suburbs: High deer pressure, especially in suburban Portland and Seattle areas. Deer are habituated to humans. Stick with snapdragons, dusty miller, and salvias.

Southeast (Tennessee, Georgia, Carolinas, Virginia): Moderate to high pressure. Marigolds and zinnias hold up better here than in the Northeast. Lantana is strongly resistant and thrives in the summer heat.

Midwest suburbs: Moderate pressure. B-rated annuals like marigolds and zinnias hold up most years. Apply repellent in April–May when pressure peaks.

Mountain West and Southwest: Lower pressure in most areas. Deer do browse, but populations are generally lower than in eastern states. B-rated annuals work without much additional protection in most Mountain West gardens.
