Long Island Native Plants: Best Species for a Garden That Belongs Here

A yard planted with regional species feeds the insects, bees, and birds that evolved alongside them — an ecological chain reaction a row of exotic imports simply cannot start. Planting native turns a decorative yard into a working part of the coastal ecosystem, and once established, these plants largely water and defend themselves.

Why Plant Native?

Because co-evolution matters. Native bees and butterflies can only reproduce on the plant species their larvae recognize — monarch caterpillars eat milkweed and nothing else. A native garden also drains better, needs no fertilizer, and shrugs off the salt spray and sandy soil that stress imported ornamentals. Every square foot planted with indigenous flora is a small repair to the suburban landscape.

Best Native Flowers

Butterfly milkweed lights up June with orange and feeds monarchs all summer. Creeping phlox carpets April in pink. White wood aster (Eurybia divaricata) covers the shady fall gap when little else blooms, and bee balm draws in hummingbird moths and pollinator swarms alike. Joe Pye weed towers over the damp corners, purple coneflower feeds goldfinches in August, and together they stretch the bloom season from March to October, so flowers attract wildlife in every month you are outside.

Native Grasses

Little bluestem turns copper in autumn, switchgrass catches winter frost beautifully, and pink muhly makes a misty pink haze in September. These grasses host skipper butterflies and add the movement that makes a planting look alive rather than planted.

Shrubs and a Vine

Bayberry fixes its own nitrogen and smells wonderful after rain; arrowwood viburnum feeds migrating birds in September. For a fence or trellis, trumpet honeysuckle — our own indigenous vine, not the invasive Asian one — hums with ruby-throated hummingbirds in July.

Where to Buy Native Plants

The local native plant scene is surprisingly deep. Dropseed Native Landscapes on the North Shore runs a nursery devoted entirely to regional species and will design a whole-yard plan for you. ReWild Long Island sells at seasonal plant sales and coaches beginners. The LINPI database documents every species recorded across the island, and LI Natives grows plugs for restoration projects. H. Eberhard Nurseries in Melville keeps a native section among its general stock.

First, Remove the Invasives

No native planting survives competition from porcelainberry, mugwort, or Japanese knotweed. Cut, dig, and smother the worst offenders before you plant — Go Native LI maintains the definitive island guide. Once the foreign bullies are gone, natives fill in fast because the soil fungus and insect pests that once held them back are still here, working in your favor.

Frequently Asked Questions

Are native plants harder to find than regular perennials?

Less so every year — the suppliers above all sell to the public, and demand keeps growing.

Do native gardens look messy?

Only if you let them. Mass the same plant species in drifts, keep clean edges, and a native garden reads as intentional as any border.

Will natives survive my sandy soil?

That is exactly what they evolved for — most island natives prefer sharp drainage and resent rich, soggy beds.

Can I mix natives with the roses I already grow?

Yes. Tuck milkweed and aster between existing beds; beneficial insects raised on natives will then patrol your whole garden.
