What to Plant in Maryland Gardens for Pollinators and Wildlife

Gardening in Maryland offers a special opportunity to support a wide variety of pollinators and wildlife. The state spans several ecological regions and USDA hardiness zones (roughly zones 6 to 8), so a thoughtful plant palette and simple habitat features can turn yards, community gardens, and small plots into rich resources for native bees, butterflies, hummingbirds, moths, beneficial beetles, songbirds, and small mammals. This article gives practical, concrete plant suggestions and landscape strategies tailored to Maryland conditions, with planting and maintenance tips you can use this season.

Principles for Wildlife-Friendly Planting in Maryland

Start with these principles so your plant choices have maximum value for wildlife.

• Plant native species whenever possible. Native plants evolved with local insects and birds and provide superior nectar, pollen, and host resources compared with most non-natives.
• Provide continuous bloom from early spring through late fall. Aim for overlapping bloom periods to supply food for multiple generations of pollinators.
• Offer host plants for caterpillars, not just nectar. Many butterflies and moths need specific plants for larval development.
• Include structural diversity: trees, shrubs, perennials, grasses, and vines. Different species use different layers for nesting, cover, and food.
• Minimize or eliminate pesticide use. Many insecticides, including some systemic products, harm pollinators and beneficial insects.
• Provide water and nesting habitat: shallow water sources, logs, bare ground, hollow stems, and native bee boxes increase habitat value.

Maryland Native Trees and Large Plants That Feed Wildlife

Trees and large shrubs are keystones for wildlife because they provide spring pollen, nesting sites, fruit, and insect prey.

Recommended native trees

• Flowering dogwood (Cornus florida) – Spring blooms for pollinators; berries feed birds in fall and winter.
• Serviceberry / Juneberry (Amelanchier spp.) – Early spring flowers for bees and sweet fruit for birds and mammals.
• Red maple (Acer rubrum) – Early pollen source for bees; supports many caterpillars.
• Black cherry (Prunus serotina) – Nectar for pollinators; host plant for many butterfly caterpillars; fruit for birds.
• Oaks (Quercus spp.) – Support hundreds of caterpillar species; important mast for birds and small mammals.

Shrubs that matter

• Spicebush (Lindera benzoin) – Host for spicebush swallowtail caterpillars; early nectar/pollen for bees.
• Viburnums (native species) – Spring flowers and late-summer berries for birds.
• Summersweet (Clethra alnifolia) – Fragrant summer flowers that attract bees and butterflies; tolerant of wet sites.

Perennials and Grasses: Season-by-Season Planting Guide

To keep nectar available, choose a mix of spring, summer, and fall bloomers. Below are reliable native perennials and ornamental grasses for Maryland.

Spring bloomers

• Wild columbine (Aquilegia canadensis) – Attracts hummingbirds and bees.
• Wild geranium (Geranium maculatum) – Early nectar for bees and flies.
• Virginia bluebells (Mertensia virginica) – Early nectar source for bumblebees.
• Pasque flower (Pulsatilla spp.) and bloodroot (Sanguinaria canadensis) – Worth adding to shady native beds.

Summer bloomers

• Bee balm (Monarda didyma) – Hummingbirds and bees love the tubular flowers.
• Cardinal flower (Lobelia cardinalis) – Excellent for hummingbirds in moist areas.
• Smooth aster (Symphyotrichum laeve) and other native asters – Late-season nectar for butterflies and bees.
• New England aster (Symphyotrichum novae-angliae) – Fall nectar source critical for migrating monarchs and other late-season pollinators.

Grasses and sedges

• Little bluestem (Schizachyrium scoparium) – Seeds for birds and structure for insects.
• Switchgrass (Panicum virgatum) – Provides cover and late-season seeds.
• Pennsylvania sedge (Carex pensylvanica) – Good low groundcover and insect habitat.

Plants That Support Specific Pollinators and Wildlife

Different animals need different plants. Below are targeted recommendations.

For native bees

Native bees need diverse flower shapes and nesting sites. Include tubular, composite, and open flowers.

• Early spring: Willows (Salix spp.), maples, dandelion alternatives like native violets.
• Mid season: Coneflowers (Echinacea purpurea), black-eyed Susan (Rudbeckia hirta), monarda.
• Late season: Asters and goldenrods (Solidago spp.) are crucial.
• Nesting: Leave patches of bare, well-drained soil for ground-nesting bees and keep some old stems or install bee boxes for cavity nesters.

For butterflies and moths

Butterflies require nectar and caterpillar host plants.

• Monarchs: Milkweeds (Asclepias syriaca, A. incarnata) for larvae and nectar from late-blooming flowers during migration.
• Swallowtails: Parsnip, dill, fennel, and native trees like black cherry and spicebush.
• Skippers and hairstreaks: Grasses and native legumes.
• Tip: Plant milkweed in sunny spots, keep some plants unmowed until caterpillars finish feeding, and avoid systemic insecticides.

For hummingbirds

Hummingbirds prefer red tubular flowers and a continuous supply of nectar.

• Cardinal flower (Lobelia cardinalis), bee balm (Monarda didyma), and trumpet honeysuckle (Lonicera sempervirens).
• Provide shrubs and trees for perches and nesting. Avoid giving sugar water if hummingbird flowers are abundant, but if used, maintain feeders clean.

For birds and small mammals

• Fruit-producing plants: Serviceberry, elderberry (Sambucus canadensis), dogwood.
• Seed-producing perennials and grasses: Coneflowers, asters, sunflowers, little bluestem.
• Shelter: Dense shrubs, brush piles, and native grasses provide nesting and winter cover.

Design and Planting Practicalities

Practical steps to translate species lists into a functioning habitat.

1. Assess your site: Sun exposure, soil moisture, soil pH, and space available. Maryland yards can vary from well-drained uplands to marshy coastal soils.
2. Choose a planting scheme that staggers bloom: Plan for at least three species in each seasonal window so pollinators always find resources.
3. Group plants in clumps of 6 to 12: Large groups of the same species are more attractive to pollinators than single specimens.
4. Prepare the soil minimally: Most natives prefer less fertile, well-drained soils. Avoid heavy amendments; add compost if soil is compacted or very poor.
5. Plant in the right season: Spring and fall are best for establishing perennials and shrubs. Fall planting gives roots time to establish before high summer heat.
6. Mulch and water for establishment only: Apply 2 to 3 inches of organic mulch, keeping it away from crowns. Water regularly the first year, then taper off as plants become established.

Maintenance and Wildlife-Supporting Practices

A wildlife garden is not a manicured show garden. Adopt practices that benefit wildlife without sacrificing appearance.

• Reduce mowing and leave a corner as a native meadow or leave seed heads through winter. Many pollinators and birds use seedheads and stems for food and nesting.
• Practice selective pruning: Trim after bloom for spring-flowering shrubs; leave late-season flowers and seedheads for overwintering insects and food for birds.
• Limit fertilizers and avoid systemic insecticides and broad-spectrum sprays. Use targeted pest control and promote beneficial insects.
• Provide water and shelter: Install a shallow birdbath or saucer with stones for insects. Keep a brush pile or dead log for shelter and overwintering insects.

Quick Plant Lists for Maryland Gardens

Below are compact starter lists for different garden sizes and conditions.

• Sunny, dry site: Little bluestem, Echinacea (coneflower), Rudbeckia (black-eyed Susan), Coreopsis, milkweed (Asclepias syriaca).
• Moist or part shade: Cardinal flower, Lobelia cardinalis, Joe-Pye weed (Eutrochium purpureum), sedges, spicebush.
• Shade or woodland edge: Virginia bluebells, wild geranium, trillium (in suitable sites), oak and dogwood canopy.
• Small urban yard or containers: Bee balm, butterfly bush alternatives that are native (Buddleia alternatives like native Clethra), asters, milkweed in a large container.

Practical Takeaways and Next Steps

• Aim for at least 50% native plant cover to maximize benefit. Even small changes matter: a single milkweed patch or a cluster of asters can make a big difference.
• Map bloom timing before planting: create a calendar of bloom to ensure continuous nectar from March through November.
• Start small and expand: convert one lawn strip or one flowerbed each year into native plantings.
• Monitor and learn: Keep a simple journal of species observed and bloom times. Over time you will refine the palette for your yard and local pollinators.

With the right plant choices and a few habitat features, Maryland gardeners can create landscapes that sustain a rich array of pollinators and wildlife while remaining beautiful and manageable. Plant for season-long resources, prioritize native species, and adopt wildlife-friendly maintenance for lasting results.
