A guide to the native plants at Argenta Brewing Company
Meet your native plant friends.

Five of these six species have grown in New England for thousands of years. The sixth, Purple Coneflower, is native to eastern North America and is thriving here at its northern range edge. Tap any plant to learn more.

Purple Coneflower
Echinacea purpurea
Blooms: Jul – Sep
+

The iconic spine of this planting, bold and upright with rosy-purple petals that sweep back from a spiny bronze cone glowing 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 winter
Echinacea purpurea is native to the central and eastern US, but its range has been creeping northward as the climate shifts. In Maine it sits at the northern edge of where it can reliably thrive, and having it here is a quiet nod to that shift. Most ecologists consider it naturalized and ecologically functional here, supporting the same specialist bees and birds it would in its core range further south.
Purple Love Grass
Eragrostis spectabilis
Blooms: 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 and we think of it as the soul of the design.

Height
1 – 2 ft
Form
Fine, airy, billowing
Birds
Song Sparrows and American Goldfinches feed on the seed heads in fall. Dark-eyed Juncos scratch for fallen seeds on the ground below.
Texture role
Finest texture in the planting. Creates depth and movement.
That reddish-purple cloud is created by the same pigments that turn maple leaves red in fall, just arriving a few weeks ahead of schedule. When seeds ripen, the whole seed head detaches and tumbles across the ground like a tumbleweed, scattering seeds as it goes without any help. Song Sparrows and Goldfinches will pick the seed heads clean through late fall.
Showy Goldenrod
Solidago speciosa
Blooms: 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, reading 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 thousands of years.

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
Blooms: 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, and hummingbirds cannot resist it.

Maine status
Native and common throughout Maine, one of the most reliable mid-summer bloomers in the Northeast
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
Blooms: 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 acts as a landing pad, with wide flat blooms perfectly designed for smaller bees and beetles that cannot access tubular flowers.

Texture role
Strong horizontal contrast to vertical plants
Named for Achilles, who legend says used yarrow to stop soldiers' wounds from bleeding 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
Blooms: Sep – Oct
+

The closer of the season, with 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.

Who visits
Who shows up when native plants are on the menu.

These six species collectively support a remarkable number 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, and 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.

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

A fast-flying native skipper confirmed in Maine. Delaware Skippers use native bunch grasses as larval host plants, making plantings like this one potential breeding habitat rather than just a nectar stop.

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.

Throughout the year
Always something on the menu.

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 this combination of plants?

Every choice in this planting was deliberate. They go together like an Argenta Generic American Lager and The Bayside and Fries from Hank & Artie's. 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.

Seeds pollinated by native bees germinate at 2 to 5 times the rate of those pollinated by European honey bees
Why it matters what kind of native
Not all native plants are created equal.

Most native plants at garden centers are cultivars — bred for showier flowers, unusual leaf color, or compact size. That breeding can change the chemical signals that specialist bees recognize, the leaf textures that specific caterpillars need, and the genetic diversity that makes a population resilient. Every plant in this planting is a straight species, sourced from local ecotypes as close to Maine's own seed stock as possible. It is a small but meaningful difference.

"Offering only cultivars for sale perpetuates the notion that plants are simply decorations and how they interact with other species is irrelevant."

Native plant design, education, and installation.
Based in North Deering, Portland, Maine

Wild Heart Nativescapes brings native plant ecosystems to residential and commercial properties across Maine. Every project uses straight species plants of local or regional ecotype as much as possible. The goal is to champion the same plants that have supported Maine's insects, birds, and soil for thousands of years.

We design, educate, and install. We source thoughtfully. And we build spaces that do something conventional landscaping rarely does: function as real habitat and consider the world beyond the human perspective.

The planting outside this great brewery is a small example of what that looks like in practice: six species, three planters, and a season's worth of ecological activity happening right here in Bayside. Get excited, it's pretty cool.
