Starting a Pollinator Garden: Design Principles and Plant Selection

How to start a pollinator garden — what to actually plant (and what to avoid), design principles that maximize insect diversity, and why the species list matters more than the aesthetic.

When to plant

Fall is ideal for most native pollinator plants — cooler temperatures and rainfall support establishment, and many natives need a cold period to break dormancy for spring growth. Spring planting works for most species with consistent irrigation for the first season. Per Xerces Society, "the most common mistake is planting a pollinator garden in May when everything at the garden center is in bloom — this misses the fall planting window and produces plants that must survive their first summer drought before establishing."

What to plant — the core species list

The most common pollinator garden mistake is planting for aesthetics first and ecology second — choosing plants because they're pretty rather than because they're ecologically functional. Per Xerces Society, "the highest-value pollinator plants are native wildflowers from the genus list developed by Tallamy and colleagues" based on caterpillar host species counts. Flowers that look pretty to humans but have no co-evolutionary relationship with local insects have minimal pollinator value.

Non-negotiable early-season plants (April–June)

Wild columbine (Aquilegia canadensis) — essential early hummingbird and native bee plant
Native violets (Viola sororia) — host plant for multiple fritillary butterfly species
Golden alexanders (Zizia aurea) — critical early-season bee plant, host to black swallowtail
Wild blue lupine (Lupinus perennis) — sole host of Karner blue butterfly
Native phlox (Phlox divaricata) — early nectar for hummingbirds and native bees

Non-negotiable mid-season plants (June–August)

Milkweed species (Asclepias incarnata, A. tuberosa) — sole monarch butterfly host plant. See our milkweed care guide.
Wild bergamot (Monarda fistulosa) — supports 100+ bee species
Purple coneflower (Echinacea purpurea, straight species) — native bee plant and bird food
Native penstemons — hummingbird and bumblebee essential
Joe Pye weed (Eutrochium purpureum) — exceptional swallowtail butterfly plant

Non-negotiable late-season plants (August–October)

Goldenrod (multiple Solidago species) — the most important fall native bee plant in the eastern U.S.
Native asters (Symphyotrichum novae-angliae, S. oblongifolius) — critical monarch migration nectar
Ironweed (Vernonia spp.) — important fall bee plant
Native sunflowers (Helianthus angustifolius, H. divaricatus) — autumn seed and nectar

What to avoid

Butterfly bush (Buddleia davidii)

Per Xerces Society, butterfly bush "provides nectar to adult butterflies but is not a host plant for any North American butterfly species — butterflies visit it like a fast food stop and then leave to find host plants that their larvae actually need." In many Pacific Northwest and mid-Atlantic states, it has naturalized invasively in riparian habitats. It is not a functional pollinator plant in the ecological sense — it attracts butterfly visitors without supporting the butterfly life cycle. Native shrubs like buttonbush, native viburnums, and sweet pepperbush provide nectar and host plant relationships.

Double-flowered cultivars

Double-flowered versions of native plants (double coneflower, double black-eyed Susan, plena forms of any flower) have modified petals in place of stamens and pistils — per Xerces Society, they provide "little to no pollen or nectar" and are essentially ornamental objects. Plant only single-flowered straight species for pollinator function.

Neonicotinoid-treated plants

Many nursery-grown plants, including those labeled "pollinator friendly," are pre-treated with systemic neonicotinoid insecticides (imidacloprid, clothianidin) that persist in plant tissue including nectar and pollen. Per Xerces Society, "neonicotinoid residues in pollen and nectar can be lethal or sublethal to bees." Ask your nursery whether plants have been treated with neonics. Certified organic plants are not neonicotinoid-treated.

Design principles for insect diversity

Per Xerces Society, "pollinator habitat with the highest insect diversity includes: plants of varying heights and flower shapes, bloom continuity from early spring through late fall, and bare ground or nesting structures for ground-nesting bees."

Flower shape variety: Native bees vary enormously in tongue length and body size. Tube flowers (penstemons, salvias) serve long-tongued bees and hummingbirds. Flat, open flowers (goldenrod, asters, daisies) serve short-tongued bees and beneficial insects. Include both types.

Structural variety: Low groundcovers, mid-height perennials (2–4 feet), and tall background plants (4–8 feet) create niches at different heights. Orb-weaving spiders, hunting wasps, and many beneficial insects use the varied structure for prey capture and nesting.

Bare ground: Approximately 70% of native bee species in North America are ground-nesting. Per Xerces Society, "including some areas of bare, undisturbed, well-drained soil near the pollinator garden provides critical nesting habitat." A sunny, south-facing slope with bare soil a few feet from the plantings is ideal. Resist the urge to mulch every inch of the garden.

What I grow in my Long Island pollinator beds

My front-facing zone 7a beds are substantially native-focused. I grow catmint, black-eyed Susan, coneflower, Russian sage, lavender, sedum 'Autumn Joy', switchgrass, and New England aster. The catmint draws spectacular numbers of bumblebees from its first June flush through the second August bloom. The coneflowers are specifically straight-species — I removed the cultivar clumps I had originally and replaced them with straight-species plants I started from seed, and the goldfinch visits increased noticeably the following fall. The switchgrass I leave standing through March for overwintering bee habitat.
