Purple Coneflower
Echinacea purpurea
Jul – Sep
+

The iconic spine of this planting. Bold, upright, and unmistakable. Its rosy-purple petals sweep back from a spiny bronze cone that glows in afternoon light. Blooms for up to two months, then holds its seed head through winter as both a sculptural form and a bird feeder.

Seed heads feed birds through January
Plains Indigenous peoples used Echinacea as their primary medicinal plant for centuries, treating colds, infections, and wounds. The same plant that heals also feeds an entire food web.
Purple Love Grass
Eragrostis spectabilis
Aug – Oct
+

The magic thread woven through the whole planting. In late summer it erupts into an airy haze of reddish-purple, a cloud of color that seems to hover above the soil. Catch it in late afternoon light and it practically glows. Landscape designers call this a matrix plant. We call it the soul of the design.

Texture role
Finest texture in the planting. Creates depth and movement.
When seeds mature, the entire inflorescence detaches and rolls like a tumbleweed, scattering seeds as it goes. Nature's own dispersal system, no help needed.
Showy Goldenrod
Solidago speciosa
Aug – Oct
+

The fall showstopper. Blazing upright wands of golden-yellow at the exact moment the season turns. Unlike its sprawling cousins, Showy Goldenrod stays tight and disciplined. It reads as an elegant vertical exclamation point. Pairs naturally with New England Aster for a classic late-season combination that has played out in Maine meadows for millennia.

Common myth
Does NOT cause allergies. That's ragweed blooming at the same time.
Goldenrod supports over 100 specialist bee species and is a critical fueling stop for Monarch butterflies on their fall migration to Mexico, a journey of 3,000 miles that depends on plants like this one.
Wild Bergamot
Monarda fistulosa
Jun – Aug
+

The mid-summer bridge. Lavender-pink ragged blooms with a distinctive spiky texture that contrasts beautifully against the bold forms around it. Crush a leaf and you get a wild oregano scent. It is in the mint family and the connection is unmistakable. Hummingbirds cannot resist it.

Height

Scent
Wild oregano when leaves are crushed
Wild Bergamot is a host plant for the Hermit Sphinx Moth, a striking clearwing moth that hovers like a hummingbird. If you spot one at dusk visiting these flowers, you are witnessing something genuinely rare.
Common Yarrow
Achillea millefolium
Jun – Sep
+

The workhorse and among the first to bloom. Flat-topped white flower clusters sit on fine, fernlike foliage, providing a strong horizontal texture that anchors all the vertical energy around it. Yarrow is the landing pad. Its wide, flat blooms are perfectly designed for smaller bees and beetles that cannot access tubular flowers.

Named for Achilles, who legend says used yarrow to staunch soldiers' wounds in the Trojan War. Archaeological evidence suggests humans have used yarrow medicinally for over 60,000 years, making it one of the oldest known medicinal plants.
New England Aster
Symphyotrichum novae-angliae
Sep – Oct
+

The closer. Deep purple-pink daisy flowers that erupt just as everything else begins to fade. A final burst of color echoes the Coneflower from midsummer and brings the season full circle. One of the most important late-season plants in the Northeast, it provides critical fuel for pollinators preparing for winter.

New England Aster is a host plant for the Pearl Crescent butterfly, a small vivid orange and black butterfly you may see laying eggs directly on these plants in late summer.
Who visits
The guests these plants invite.

These six plants collectively support dozens of pollinator species native to the Northeast. Here are the ones most likely to visit this planting.

Maine sits in one of the most pollinator-rich regions of North America. The Northeast supports over 400 native bee species, dozens of butterfly species, hummingbirds, and countless moths. Many depend entirely on native plants like these to complete their life cycles. A planting like this isn't just decorative. It's a food source, a nursery, and a rest stop on a much longer journey.
Bees
Common Eastern Bumblebee
Visits: Coneflower · Bergamot · Goldenrod · Aster

Maine's most visible pollinator. Her long tongue reaches Bergamot's tubular flowers that shorter-tongued bees simply cannot access. A single colony visits millions of flowers in a season.

Mining Bees (Andrena spp.)
Visits: Coneflower · Aster · Goldenrod

Specialist native bees that are among the first to emerge in spring. Several Andrena species are aster specialists and depend on Symphyotrichum pollen almost exclusively to feed their larvae.

Sweat Bees (Halictus spp.)
Visits: Yarrow · Goldenrod · Coneflower

Small, metallic bees that are often the first you'll notice on Yarrow's flat flower heads. Their size makes them perfectly suited to the open, accessible architecture of flat-topped blooms.

Leafcutter Bees (Megachile spp.)
Visits: Coneflower · Bergamot

Solitary cavity-nesting bees that carry pollen on their abdomen rather than their legs. Watch for the tell-tale semicircular cuts they make in nearby leaves to line their nests.

Butterflies
Monarch
Visits: Goldenrod · Aster · Coneflower

The most iconic migrating butterfly in North America, passing through Maine each fall on its way to Mexico. Goldenrod and Aster are critical fueling stops. Without late-season nectar, the migration fails.

Eastern Tiger Swallowtail
Visits: Bergamot · Coneflower · Yarrow

Maine's largest butterfly, with a 4-inch wingspan. Drawn strongly to Bergamot and Coneflower, it is one of the most striking visitors this planting will attract.

Pearl Crescent
Host plant: Aster · Visits: Yarrow · Coneflower

A small orange and black butterfly that uses Symphyotrichum asters as a host plant. It lays eggs directly on New England Aster leaves and the caterpillars feed on the foliage.

Zabulon Skipper
Host plant: Love Grass · Visits: Bergamot · Yarrow

A fast-flying skipper that uses Purple Love Grass as a larval host plant. Because Love Grass is in this planting, this species does not just visit. It can complete its full life cycle right here.

Other visitors
Ruby-throated Hummingbird
Visits: Bergamot

Maine's only breeding hummingbird. Wild Bergamot's tubular lavender flowers are one of its preferred nectar sources. They typically arrive in May and migrate south in September.

Hermit Sphinx Moth
Host plant: Bergamot

A clearwing moth that hovers like a hummingbird and is easily mistaken for one at dusk. Wild Bergamot is its host plant. If you see one here, it's one of the more remarkable sightings this planting can produce.

American Goldfinch
Visits: Coneflower · Goldenrod seed heads

Goldfinches time their nesting to coincide with Coneflower seed production. In fall and winter you may see them clinging to the dried seed heads of Coneflower and Goldenrod. That is exactly why we leave them standing.

Hover Flies (Syrphidae)
Visits: Yarrow · Goldenrod · Aster

Often mistaken for bees, hover flies are important pollinators that favor flat, open flowers. Yarrow is a particular favorite. Their larvae prey on aphids, making them a form of natural pest control as well.

Across the year
Something in bloom, always.

This planting was designed so that color, texture, and life are present from spring through the first hard frost and into winter.

A note on winter

We intentionally leave seed heads standing through winter. Coneflower and Goldenrod seed heads feed Goldfinches and Chickadees when other food sources disappear. The dried stems also provide nesting material and look genuinely beautiful under a dusting of snow.

Design intention
Why these plants, together.

Every choice in this planting was deliberate. Here's the thinking behind it.

Texture contrast
Broad daisy forms (Coneflower, Aster), flat plates (Yarrow), ragged pom-poms (Bergamot), feathery plumes (Goldenrod), and a fine airy haze (Love Grass). Five distinct textures that play off each other rather than compete.
Height layering
Taller structural plants run the center spine of each planter. Shorter plants flank the edges. Viewed from any angle, you see depth rather than a flat wall of foliage.
Root harmony
Each species occupies a different root depth. Love Grass feeds from the top 6 inches. Yarrow and Bergamot from 6 to 10 inches. Coneflower and Goldenrod reach deeper. No competition. Each plant has its own zone.
The Oudolf method
This design follows the principles of Piet Oudolf, the Dutch designer behind NYC's High Line. Plants are chosen for their full-season presence, not just peak bloom. Structure, movement, and even winter decay are all intentional parts of the design.
Color through seasons
White and lavender in early summer (Yarrow, Bergamot). Bold purple-pink in midsummer (Coneflower). Gold and bronze in fall (Goldenrod, Love Grass). A final purple close (Aster). The planting tells a seasonal story.
Ecological design
These six species collectively support dozens of bee species, migrating Monarchs, breeding butterflies, and winter songbirds. Beauty and biodiversity are not in tension here. They are the same thing.
Root depth cross-section

Each species in this planting occupies a distinct depth zone underground. There is no competition. Every plant has carved out its own territory in the soil column, which is one reason this palette works so well together in a confined container.

The quiet revolution

Native plants are not just pretty. They are the original infrastructure of life in this region, and every planter out front is a small act of restoration.

Healthy ecosystem
that sustains itself

Nearly all land birds raise their young on caterpillars. Caterpillars need native plants to eat. Remove the plants and the whole chain unravels.

The lawn problem
40 million acres of lawn. Almost nothing lives in it.

Turf grass is essentially a biological desert. It supports almost no native insects, produces no food for wildlife, and requires enormous water and chemical inputs just to maintain. It is the most irrigated crop in America and it feeds nothing.

The good news
Small spaces do big things.

You don't need an acre. A planter works. A window box works. A parking lot edge works. Native plants in even a small space create real habitat. And when those small spaces connect, they form corridors that wildlife can actually move through.

The people behind the plants
Wild Heart Nativescapes

A native plant design and installation practice based in Portland, Maine.

We design and install native plant landscapes for homes, businesses, and public spaces throughout coastal Maine. Our work is rooted in the belief that the most beautiful gardens are also the most ecologically alive, places where wildness and intention coexist.

Every plant we use is native to the Northeast. Every design is built around the idea that a planting should look better in year three than year one and better at dusk than noon. We don't fight nature. We work with it.
