What To Grow In Virginia To Support Beneficial Predators

Virginia’s varied landscapes, from coastal plains to mountains, support a wide array of beneficial predators that keep pest populations in check. Thoughtful plant selection and landscape design can dramatically increase populations of lady beetles, lacewings, predatory ground beetles, parasitic wasps, spiders, birds, and bats–reducing the need for chemical controls and creating healthier gardens, farms, and yards. This guide explains what to grow in Virginia, when to plant, and how to manage habitat to favor beneficial predators year-round.

Why plant for predators in Virginia

Virginia spans USDA hardiness zones roughly 5 through 8 and includes diverse ecoregions. That variation allows you to choose many native and adapted species that provide nectar, pollen, alternate prey, shelter, and overwintering habitat. Beneficial predators need more than a single flower patch: they need continuous bloom, structural diversity, and places to shelter and overwinter.
Planting for predators benefits both small-scale vegetable gardens and larger farms. Predators are self-sustaining biological control agents: once established, they respond to pest outbreaks quickly, reduce reliance on insecticides, and contribute to pollination and overall ecosystem resilience.

Key design principles

Plant choice matters, but so does design and management. Use these core principles as you plan.

Provide continuous bloom from early spring through late fall to feed adult predators that require nectar and pollen.
Include a mix of flower shapes and sizes (umbels, composites, tubular flowers) to serve different predator groups, especially small parasitic wasps and hoverflies.
Maintain structural diversity: trees, shrubs, perennials, grasses, and groundcovers offer nesting and overwintering sites.
Leave refuges: brush piles, hedgerows, unmown strips, and leaf litter support ground beetles, spiders, and overwintering lady beetles.
Minimize broad-spectrum insecticide use and avoid treating insectary plantings. If pest control is needed, use targeted methods and apply at times least harmful to predators.
Provide water and mud sources for some predators and wild bees; shallow dishes, damp sand, or drippers work.

Top plants for Virginia that attract beneficial predators

Below is a practical list of species and plant groups, selected for performance in Virginia and value to beneficial predators. Include several of these in every garden to ensure seasonal continuity.

Native asters (e.g., Symphyotrichum novae-angliae, S. oblongifolium) — bloom late summer to fall; crucial for late-season aphid-eating predators and wasps.
Goldenrod (Solidago spp.) — late-season nectar source for syrphid flies, wasps, and lacewings; supports migratory beneficial insects.
Joe-Pye weed (Eutrochium purpureum) — tall, summer-blooming umbel-like flower heads that attract wasps, hoverflies, and predatory flies.
Black-eyed Susan (Rudbeckia hirta) — long bloom period; accessible nectar and seed for birds that prey on insect pests.
New England aster, and other native asters — important fall nectar.
Yarrow (Achillea millefolium) — flat-topped flowers favored by parasitoid wasps and hoverflies; drought tolerant.
Milkweeds (Asclepias spp.) — not just for monarchs; flowers provide nectar for many predatory insects; common milkweed and butterfly weed are good Virginia choices.
Native golden Alexanders and other umbellifers (e.g., Zizia aurea) — early to mid-spring nectar for tiny parasitic wasps.
Buckwheat (Fagopyrum esculentum) — fast-growing annual used as a cover crop/insectary; excellent short-term nectar source to boost parasitoids.
Sweet alyssum (Lobularia maritima) — low-growing annual that supports hoverflies and tiny parasitoids around vegetable beds.
Dill, fennel, coriander, parsley (Apiaceae herbs) — attractive to lacewings, hoverflies, and parasitic wasps when allowed to flower.
Sunflowers (Helianthus annuus and native perennials) — provide nectar for insects and seeds for birds; large flowers host many predators.
Native shrubs like Viburnum dentatum (arrowwood viburnum), Sambucus canadensis (elderberry), and Ilex verticillata (winterberry) — provide multi-season structure and shelter; spring flowers feed predators.
Native trees, especially oaks (Quercus spp.) and willows (Salix spp.) — oaks support massive insect communities (and thus predators); willows offer early nectar and pollen for early-season predators.

Plants to prioritize by season

Selecting species that bloom in different seasons creates a continuous resource corridor for predators.

Early spring (March-May)

Willows (Salix spp.) — catkins provide early pollen and nectar.
Native early-blooming shrubs (Cornus florida, Amelanchier) — support early-emerging predators.
Spring-flowering bulbs and perennials (e.g., native violets, bloodroot) — provide early-season resources and shelter.

Late spring to summer (May-August)

Umbelliferous herbs (dill, fennel, cilantro left to flower) — feed parasitic wasps and hoverflies.
Joe-Pye weed, coneflower (Echinacea), Rudbeckia — mid- to late-summer nectar sources.
Buckwheat planted as a short-term insectary crop during lettuce or brassica rotations.

Late summer to fall (August-November)

Goldenrod and asters — critical late-season nectar for maintaining predator populations through migrations and into overwintering.
Sunflowers and late-blooming perennials.

Which predators are you helping, and what do they need?

Understanding predator preferences helps you choose the right plants.

Lady beetles (ladybugs): Feed on aphids, scale, and mites. Adults need pollen and nectar in times of low prey–pollen-rich plants like Alyssum, dandelion, and Asteraceae are valuable. Provide overwintering sites: leaf litter, bark crevices, hollow stems.
Lacewings: Larvae eat aphids and small caterpillars. Adults consume nectar and pollen from umbel flowers and composites such as yarrow, dill, fennel, and goldenrod.
Parasitic wasps (tiny braconids and ichneumonids): Require small flowers and flat inflorescences for nectar–umbels and flat-topped composites are ideal.
Hoverflies (Syrphidae): Adults feed on nectar/pollen; larvae feed on aphids. Sweet alyssum, buckwheat and umbellifers attract them.
Ground beetles and rove beetles: Predators of slugs, snails, cutworms. They need shelter at ground level: mulch, stone borders, brush piles, and beetle banks.
Spiders: Generalist predators that require structural complexity–ornamental grasses, shrubs, and undisturbed corners.
Birds and bats: Feed on larger insect pests; support them with native trees, snags, bat boxes, and a diversity of plants that support insect prey.

Practical planting plans for common Virginia settings

Different scales call for different approaches. Below are actionable plans.

Small vegetable garden (backyard, 100-400 sq ft)

Reserve a 2-4 ft insectary strip along one side. Plant alternating rows of alyssum, buckwheat (short-term), dill, fennel, and nasturtiums.
Interplant single or small clusters of asters, yarrow, and Rudbeckia among the beds for continuous bloom.
Leave a corner with brush, stacked logs, and leaf litter for overwintering.

Suburban yard or pollinator-friendly lawn (1/4-1/2 acre)

Convert a portion of turf to mixed native meadow: goldenrod, asters, coneflower, and Joe-Pye weed.
Plant a hedgerow of native shrubs (viburnum, elderberry, bayberry) along property boundaries for shelter and structural diversity.
Install a bat box and bird nest boxes to encourage vertebrate predators.

Small farm or orchard

Establish insectary strips between crop rows (10-20 ft wide) with mixtures of buckwheat, clovers, yarrow, and native forbs.
Plant permanent hedgerows of native shrubs and trees as windbreaks and habitat corridors.
Time mowing of insectary strips to avoid peak bloom and allow seeds to mature after beneficials breed.

Management tips and common pitfalls

Planting is only step one. How you manage those plants determines predator success.

Avoid broad-spectrum insecticides, especially during bloom. Use spot treatments and back-of-row gastric baits only when necessary.
Delay spring clean-up: leave stems and leaf litter through early spring to preserve overwintering predators.
Stagger planting and choose varieties with different bloom times to avoid nectar gaps.
Use native species where possible; they host more native prey and support local predator life cycles.
If using cover crops like buckwheat, plant them in short rotations timed with crop cycles to boost predator populations during vulnerable periods.
Keep a small water source: a shallow saucer with pebbles, or drippers creating damp soil, benefits many insects.
