Full-Sun Perennials for a Cottage Garden

What's proven in my garden, what's new & what I'd plant again.

GARDEN ZONE: USDA 7a/7b

GARDEN STYLE: Colorful, romantic, slightly wild

SUN: Primarily full sun

EXPERIENCE: A mix of established favorites + first-year additions

I wanted my flower garden to feel romantic, colorful, abundant and a little wild—more cottage garden than perfectly manicured landscaping.

Some of these plants have earned their place after years in my garden. Others were planted this spring, so I'm not going to pretend I know how they'll perform long-term yet.

Here's the short list.

THE PROVEN FAVORITES

01 | BEARDED IRIS

★★★★★

THE LOOK: Tall, romantic, old-fashioned blooms

BEST FEATURE: Reliable spring flowers

THE CATCH: Post-bloom cleanup

My bearded irises are reliable bloomers and absolutely beautiful.

The downside comes after the show is over. If I don't stay on top of maintenance after bloom time, they can start looking pretty rough.

Still completely worth it.

PLANT AGAIN? ✓ Absolutely

02 | PEONIES

★★★★★

THE LOOK: Huge, fluffy, romantic blooms

BEST FEATURE: The showstopper

THE CATCH: They need support

If I could pick one flower purely for drama, it might be the peony.

The blooms are huge, and mine have become more plentiful each year. They make the entire garden feel romantic when they're in bloom.

The tradeoff is all that flower has some serious weight to it. Once they're loaded with blooms, mine become top-heavy and need stakes or another form of support.

PLANT AGAIN? ✓ Without hesitation

03 | KNOCK OUT ROSES

★★★★☆

THE LOOK: Big punches of hot pink

BEST FEATURE: Tons of color + beautiful fragrance

THE CATCH: Bugs

My Knock Out roses put on a gorgeous hot-pink display, and I love their smell.

Unfortunately, the bugs apparently love them too.

They get eaten more than I'd like, so these haven't been completely hands-off for me. Even with that annoyance, the amount of color they bring to the garden makes them worth keeping.

PLANT AGAIN? ✓ Yes

04 | SALVIA

★★★★☆

THE LOOK: Wispy purple flower spikes

BEST FEATURE: Nearly impossible to kill

THE CATCH: Can get wiry

My salvia seems practically impossible to kill.

That's both its greatest strength and occasionally its problem.

If I let it go, it can grow out of hand and start looking wiry rather than whimsical. Pruned correctly, though, it's beautiful—especially the different shades of purple mixed among fuller flowers.

PLANT AGAIN? ✓ Yes

05 | GLADIOLUS

★★★★☆

THE LOOK: Tall, colorful and dramatic

BEST FEATURE: Vibrant color

THE CATCH: Needs support

Gladiolus flowers are unique.

The tall flower spikes add a completely different shape to the garden, and the vibrant colors break up all the softer pinks and purples.

But like my peonies, they need some help staying vertical.

Without stakes, mine have a tendency to fall over.

PLANT AGAIN? ✓ Yes

FIRST-YEAR IMPRESSION

Most of the rest of my cottage garden was planted this spring.

Visually, I love how these plants work together.

But there's a difference between something looking beautiful for its first few months and something proving itself to be a hardy, reliable garden plant.

So I'm withholding long-term ratings until they've had time to earn them.

LONG-TERM RATING: Pending

ALSO IN MY GARDEN

HOSTAS + LIRIOPE

These are part of my overall garden, but I wouldn't put them on my full-sun perennial recommendation list.

Hostas generally shine in shadier conditions, while liriope serves more as a durable edging/groundcover plant than one of the flowering stars of my cottage garden.

They're useful—just doing a different job.

AZALEAS

Azaleas are flowering shrubs rather than herbaceous perennials. They also generally prefer some protection from intense afternoon sun depending on the variety, so I wouldn't treat them exactly like the full-sun plants in this list.

HOW I GET THE COTTAGE LOOK

I don't think this look comes from finding one perfect flower.

It comes from layering.

LOW + SPREADING

Creeping phlox. Candytuft. Dianthus.

MID-HEIGHT + FULL

Peonies. Coneflowers. Daisies. Black-Eyed Susans. Lavender. Salvia. Foxglove. Delphinium. Lilies.

TALL + AIRY

Bearded iris. Gladiolus. Hollyhock.

STRUCTURE

Knock Out roses. Ringo rose. Azaleas. Butterfly bush.

The different heights keep the garden from looking flat, while repeating colors and flower shapes keeps all the variety from becoming chaotic.

WHAT I'VE LEARNED SO FAR

STAKE THE SHOWSTOPPERS.

Some of my most dramatic flowers are also the least capable of standing upright on their own.

Peonies and gladiolus both need support in my garden.

HARDY DOESN'T MEAN ZERO MAINTENANCE.

My iris reliably returns, but it needs cleanup.

My salvia refuses to die, but it looks much better when properly pruned.

My roses bloom beautifully, but bugs find them.

Reliable and maintenance-free aren't necessarily the same thing.

LOOK AT THE WHOLE GARDEN.

Some plants aren't necessarily the star individually.

Their value becomes obvious when they're next to something completely different.

Tall spikes behind huge round peonies. Tiny flowers spilling along the front. Purple woven between hot pink, white and yellow.

The combination is the point.

THE SHORT LIST

SHOWSTOPPER★★★★★ Peony

MOST RELIABLE★★★★★ Bearded iris

HARDEST TO KILL★★★★☆ Salvia

BEST COLOR PUNCH★★★★☆ Knock Out rose

MOST FUN★★★★☆ Hollyhocks

BIGGEST RECURRING ANNOYANCE Staking top-heavy flowers

CHECK BACK NEXT SEASON

I'm not calling something a hardy perennial I swear by because it survived a few months in my garden.

As these newer plants go through their first North Eastern winter and return—or don't—I'll update this guide with what actually happened.

Because pretty at the nursery and proven in the garden are two different things.
