Fall Perennials That Will Give Your Cottage Garden the Wow Factor

Every September, the garden starts trading its bright summer colors for the deeper, earthier tones of fall, and that’s when the perennials are really important. While a lot of the annuals are winding down, these are just hitting their stride.

Here are eight of my favorite fall perennials for a cottage garden, plus how I care for them as we head into winter, and answers to the questions I get asked most. Every one of these is growing somewhere in my Zone 8b beds right now.

What are Fall Perennials?

Fall perennials are plants that bloom or peak in autumn, carrying color and interest through the season when a lot of the garden is starting to fade. They come in every color, shape, and size, and they’re the easiest way to stretch the garden’s beauty into the later part of the year.

Why Fall Perennials Belong in a Cottage Garden

Beyond the obvious, that they keep the garden looking alive, fall perennials pull real weight in a cottage garden:

8 Best Fall Perennials for a Cottage Garden

There are plenty of fall perennials to choose from, and your local nursery likely has them in stock right now. Here are the ones I keep coming back to.

1. Sedum ‘Autumn Joy’

The look of sedum shifts throughout the whole year, but fall is when it’s most stunning. The succulent-like leaves and upright stems give it a texture and structure that plays well against softer cottage-garden plants.

The flowers go through an entire sequence as they develop green broccoli-like buds in midsummer, opening to dusty-pink heads, deepening to rose-red in late summer and early fall, then finishing bronze-red. Even after the season ends, the dried seed heads hold their shape and catch the frost. Leave them standing, and the birds will thank you.

Hardiness Zones	3-9
Features	Low-maintenance; deer-resistant; drought-tolerant; disease-resistant once established; attracts pollinators
When to Plant	Plant in spring after the threat of frost has passed and before the summer heat.

2. Black-Eyed Susans (Rudbeckia)

Those bright yellow petals on tall stems give a late-summer and early-fall garden the pop of color it needs when things start to fade. Once the flowers finish, the seed heads carry winter interest, and the birds come from the seeds, which is half the fun of leaving them up.

Hardiness Zones	3-9
Features	Attracts pollinators; low-maintenance; drought-tolerant; long-lasting blooms
When to Plant	Plant in spring after all danger of frost, or in fall. Avoid planting in the heat of summer.

3. Dahlias

It’s no secret that dahlias are my favorite fall perennial. They take their time, usually not throwing a bloom until the end of July, but they’re worth the wait.

Once they start, they keep going right up until the first hard frost, and they carry the fall garden beautifully.

Hardiness Zones	6-11 (grown as tender tubers; lift and store over winter in colder zones)
Features	Come in nearly every color; bloom in fall until the first hard frost; make gorgeous cut flowers; and the more you cut, the more they produce
When to Plant	Plant tubers in full sun in late spring, after the danger of frost.

4. Asters

These daisy-like flowers bloom in late summer and fall in a whole rainbow: purple, blue, white, and pink, and the late-season pollinators can’t get enough. Bees, butterflies, and hummingbirds all work them.

Asters are low-maintenance and generous, which is everything you want this time of year.

Hardiness Zones	3-8
Features	Attracts pollinators; low-maintenance; divide the root clumps every three years or so to propagate
When to Plant	Spring and fall are both good. In colder regions, plant by early fall so the roots establish before winter.

5. Chrysanthemums

Mums are classic fall cottage-garden perennials, in colors from soft pastels to bold, bright hues. For the longest-lasting display, pig plants with buds just starting to open rather than ones already in bloom.

To overwinter them as perennials in colder zones, get them in the ground as early in fall as you can and mulch well once the ground freezes.

Hardiness Zones	4-9
Features	Attracts butterflies; lasts up to two weeks in a bouquet; versatile growth habit
When to Plant	Plant in early spring or in fall at least six weeks before the first hard frost.

6. Coneflower (Echinacea)

Coneflowers bloom from late spring through summer. Depending on the variety and your climate, they often grow into fall.

They add a reliable pop of color and make an easy bridge from summer into the cooler months, and the seed heads feed the birds if you leave them.

Hardiness Zones	4-9
Features	Low-maintenance; attracts pollinators; disease-resistant
When to Plant	Plant in spring after the danger of frost, or in early fall at least six weeks before the first hard frost.

7. Japanese Anemone

Japanese anemones are a great flowering perennial for the transition from summer to fall. The flowers are delicate and almost paper-like, pink or white with a cluster of yellow stamens in the center. They are held on tall, wiry stems that sway with the breeze.

Graceful and timeless, they are exactly the kind of flower a cottage garden needs in autumn.

Hardiness Zones	4-8
Features	Low-maintenance; attracts pollinators; drought-tolerant once established
When to Plant	Plant after the danger of frost in spring through early fall.

8. Tickseed (Coreopsis)

Tickseed does most of its blooming in late spring and summer, but wide varieties throw a second flush in fall, which stretches the season even more. As summer turns to autumn, those daisy-like flowers bring a fresh burst of color.

The name comes from the seeds, which look like little ticks. You’ll find it as both an annual and a perennial, with hundreds of species and cultivated hybrids to choose from.

Hardiness Zones	2-11
Features	Attracts pollinators; low-maintenance
When to Plant	Plant from spring through early fall.

How to Care for Fall Perennials

A little care now keeps perennials healthy through winter and sets them up for next year. Here’s what I do before heading into the cold months.

Cut Back Spent Foliage and Flowers

As perennials finish blooming, trim the spent stalks and remove any dead or yellowing foliage. It tidies things up and helps prevent disease. A few plants are exceptions. Read more on that in the FAQs below.

Divide and Transplant

Early fall is a great time to divide and transplant perennials that are overcrowding other plants in the garden. This rejuvenates the plant and gives you free plants for other spaces in the garden.

Keep Watering, Then Ease Off

Keep watering through any dry spells so plants build strong roots before winter, especially anything recently planted. As the weather cools, taper the frequency back. They need less, but don’t let them go bone dry.

Mulch the Beds

A layer of mulch around the base of your perennials conserves moisture and insulates the roots against temperature swings. Use a few inches of something organic, wood chips, fallen leaves, or straw, and keep it off the stems.

Fertilize Lightly

In early fall, you can give perennials a balanced, slow-release fertilizer for the nutrients they’ll need next season. Follow the label rates for whatever you’re using.

Watch for Frost

Keep an eye on the forecast and be ready to cover tender plants with a blanket, burlap, or frost cloth if a hard frost is coming.

Stay on Top of Weeds

Fall is a good time to clear out any weeds that have crept in, since they compete with your perennials for water and nutrients.

Leave Some Seed Heads

Deadhead the spent flowers, but leave some seed heads standing on plants like coneflower and black-eyed Susans to feed the birds through winter.

Plant New Perennials and Spring Bulbs

Fall’s cooler temperatures and moist soil make it a good time to plant new perennials. It’s also the season to plant spring bulbs such as tulips and daffodils in the ground. Bulbs are one of the easiest ways to guarantee a colorful spring. You’re basically laying the groundwork now.

Plant for Spring

Use these quieter weeks to plan for next spring. Jot down what thrived, what flopped, and what you’d change while it’s still fresh in your mind.

Common Questions About Fall Perennials

What Perennials Should Not Be Cut Back in the Fall?

Plenty of perennials benefit from a fall trim, but some are better left standing until spring, either because they offer winter interest and food for wildlife or because cutting them back early leaves them vulnerable. Leave these alone until spring:

Which Perennials Can You Plant in the Fall?

Yes, fall is a great time to plant many perennials. It lets them establish roots before winter and gives them a head start on the growing season. Good candidates for fall planting include:

Is It Better to Plant Perennials in Fall or Spring?

Fall planting is an excellent choice in many regions, though the best timing depends on your climate and the specific plant. Fall’s advantages: roots get time to establish before winter, cooler temperatures mean less transplant shock, the soil is still warm enough to encourage root growth, and steadier rainfall means less watering. Some fall-planted perennials even bloom the following spring.

Here are a few things to weigh, though. In regions with severe winters, spring planting after the frost danger passes is often safer. Some perennials like a spring start, so it’s worth researching the ones you’re planting. And whenever you plant, prep the soil well, mulch to insulate and hold moisture (keeping it off the stems), and keep an eye on soil moisture until things settle in.

Is October Too Early to Cut Back Perennials?

In many regions, October is right on time, but it depends on your climate and what you’re growing. A few guidelines:

Final Thoughts on Fall Perennials

Mix a few of these into your beds, and the fall garden stays vibrant right through the season, and the local pollinators and birds get fed on their way into winter. Not a bad trade for plants that mostly take care of themselves.
