Top 15 Fall-Blooming Flowers for Your Perennial Garden

Keeping your perennial garden glorious into fall with flowers

Fall flower gardens can be spectacular with bold combinations of jewel-toned colors of purple, rust, scarlet, and gold. To have an abundance of flowers in the fall, you just need to do some planning early in the gardening season. For fall flowers to be hardy in your garden, plant them in the spring or summer so that they have time to become established. Fall flowers may bloom late, but they bloom best if they have been in the garden all season.

Considerations and Tips

When planning your fall garden, besides selecting plants that have a late bloom period, you want to be certain that they will bloom in your area before frost hits. Check the packaging for bloom timing, and stick to plants that work for your zone for best results. Your local nursery can offer advice if you are unsure. 

Another thing to take into consideration is that fall bloomers can get tall and leggy. The plant focuses on putting out leafy top growth all summer, so when it blooms, it is often top heavy and falls over. To ensure your fall display is as glorious as it should be, you have a handful of options: 

  • Stake the plant: Do this as it grows, early in the season. This can be a tedious chore, but it will keep it upright and tall. There is no way to straighten and stake a plant that has already bent over.
  • Plant your fall-bloomer in the back of the border: You can allow it to grow as tall as it likes. The shorter plants in the front will support it and, as an added plus, will hide the fall-blooming plant until it is its turn to shine. It is also less work than staking.
  • Periodic pruning: Make the plants stockier and more self-supporting. If you start cutting the plant back when it reaches about 6 to 8 inches tall, it will branch out and set more flower buds. Keep doing this every three to four weeks until about July 4, and then let it grow on its own for the rest of the summer. You will have a shorter but bushier plant. Keep in mind that when you prune your plants, you delay the bloom period by a week or more. Also, not all plants respond to pruning, so do some research on your specific plant before you start cutting.

    Balloon Flower

    Balloon Flower (Platycodon)

    Marie Iannotti

    Balloon flower (Platycodon grandiflorus) is in the campanula or bellflower family, but its flowers are a bit more dramatic. It starts off as a puff or bubble and pops open when it is ready to bloom. Balloon flower is a profuse bloomer in lavender-blue, pale pink, or white. The plants spread slowly, filling in without becoming a nuisance. Other than cutting the plants back in the spring or fall, virtually no other maintenance is required. Plant it throughout U.S. Department of Agriculture hardiness zones 3 through 9.

    Blue Mist Shrub

    Caryopteris (Blue Mist Shrub)

    Marie Iannotti

    Caryopteris, the blue mist shrub, is actually a subshrub that is often grown in the perennial garden. Blue mist shrub slowly opens its blossoms throughout August with dazzling blue flower clusters. Just try and keep the butterflies and bumblebees away. Blue mist shrub should be cut back in early spring like a butterfly bush (Buddleia) because it blooms on new wood. The gray-green foliage is attractive all season. Plant it in zones 5 through 9.

    Goldenrod

    Goldenrod Flowers (Solidago)

    Goldenrod (Solidago) has suffered from the mistaken notion that it exacerbates hay fever. Ragweed is the real culprit, not goldenrod. This is one of the last flowers to bloom in the fall. Most varieties are tall and stately; however, there are also several dwarf varieties available for the front of the border. Newer goldenrod cultivars do not spread by rhizomes, the way the species does, so they do not take over the whole garden. Plant it in zones 4 through 8.

    Japanese Anemone

    Japanese anemones (Anemone x hybrida) are standards in most billowing perennial borders. It starts blooming in late summer and goes straight through until frost. Each plant is covered in elegant, paper-like blooms. Japanese anemones will take a few years to become established, but once it settles in, it requires little maintenance. It will self-sow, but not aggressively, and gardeners often welcome the volunteers. Enjoy it in zones 4 through 8.

    Joe Pye Weed

    Joe Pye Weed (Eupatorium purpureum)

    Marie Iannotti

    Joe Pye Weed is one of those native plants you take for granted because you see it by the side of the road. The species can get a bit out of hand and aggressive, but newer cultivars make a wonderful backdrop to a garden border. Many of the newer Eupatorium hybrids have been bred to grow shorter with less of a weedy nature, but the dense mop heads of mauve flowers still blend in beautifully in the fall garden. It also has a white-flowered variety. It thrives just about everywhere from zones 2 through 9.

    Mums

    Hardy Fall Mums

    Marie Iannotti

    Mums (Chrysanthemum) and pumpkins are the flag bearers of fall. Many mum varieties are available, but not all are particularly hardy. The plants sold in the north in the fall as "hardy mums" should have been sold to folks in the spring to be reliably hardy there. However, if you buy yours in the fall, get them in the ground ASAP. Keep them well watered and mulch them when the ground freezes to stand your best chance of having truly hardy mums. It is viable in zones 3 through 9.

    New York Daisy/Michaelmas Daisy

    Asters - fall Blooming Flowers

    Marie Iannotti 

    In shades of pink, purple, blue, and white, these delicate daisy-like blossoms start popping open in late August and continue until frost. Pinching the stems back in the early summer turns these asters into dense mounds with dozens of flower buds.

    Many varieties of the New York daisy (Aster novi-belgii) will tend to creep throughout your garden, but its airiness allows it to blend particularly well with other flowers. It thrives in zones 4 through 9.

    Russian Sage

    Russian Sage in Bloom

    Marie Iannotti

    Russian sage (Perovskia atriplicifolia) flowers sneak up on you. It starts off as a barely perceptible hint of blue and finally erupt into a hazy cloud of purple-blue that lasts for weeks.

    Like the blue mist shrub, Russian sage is considered a subshrub. Although its stems do get woody and it might not die back to the ground, it will still need to be pruned in the spring because the flowers form on the new growth. Plant it in zones 4 through 9.

    Snakeroot

    Cimicifuga (Actaea racemosa)

    Marie Iannotti

    Snakeroot (Actaea racemosa, formerly Cimicifuga) makes a wonderful focal point in the fall garden. If you shy away from the bold colors of fall, snakeroot may be just the ticket for you. This plant grows well in partial shade, where a little drama is always welcome. The plant itself grows only to about 3 to 4 feet tall, but the flower stakes will shoot up 6 or 7 feet in height. Snakeroot takes a while to become established, but be patient; it is worth it. Plant in zones 3 through 7.

    Sneezeweed

    Helenium (Sneezeweed)

    Helenium is making a resurgence in gardens. These blooms look like small, russet-toned coneflowers, displaying rich reds, yellows, and oranges. Many can grow quite tall and will need to be staked or pinched. Like clematis, it likes cool feet and hot heads, so plant it in full sun but use mulch or plant it with shorter plants that will cover their roots and keep them cool. This is also a good choice for poorly drained areas. It does well throughout zones 3 through 9.

    Stonecrop

    Tall Sedum in Flower

    Xuanyu Han

    "Autumn Joy" comes as close to perfection as any plant can. It looks good all year, requires minimal attention, and attracts few problems. The only drawback of Stonecrop (Sedum sp.) is that it is not deer resistant. The "Autumn Joy" cultivar has been joined in the garden by a growing number of fall wonders, such as "Bertram Anderson," "Brilliant," and "Matrona." No fall garden is complete without sedum. Grow it in zones 3 through 9.

    Sunflower

    Helianthus (Perennial Sunflower)

    DEA/G. NEGRI

    Many gardeners are more familiar with annual sunflowers (Helianthus annuus), which can grow 10 feet tall and show off plate-sized flowers. But Helianthus is a large genus of flowers that is perennial and blooms toward the end of the season. You will still get yellow, daisy-like flowers with modestly-sized blooms. And, there will be plenty of them. Another plus, it will not topple over the way annual sunflowers do. Grow it throughout zones 3 through 9.

    Autumn Crocus

    You are probably familiar with the spring-blooming crocus, but this little beauty does not put on its show until fall. Autumn crocus (Colchicum speciosum) grows best in partial shade, and a little dampness is always welcome. It grows only a few inches tall and makes a wonderful carpet, scattered under trees and along walkways. All parts of the plant are poisonous, which means deer, rabbits, and other four-footed pests steer clear of them. Plant it in zones 4 through 9.

    Tickseed

    Coreopsis Flowers

    The Coreopsis genus is home to many popular garden plants. Most bloom periodically throughout the summer season, but if you prune it back after flowering, it will put on a glorious fall display. The cheery yellow flowers may be the most familiar, but tickseed comes in other colors too, such as red and pink. Most diseases and pests avoid this plant. Enjoy it in zones 4 through 9.

    Turtlehead

    Chelone (Turtlehead)

    Marie Iannotti

    Chelone lyonii got its nickname from the blossoms, which are shaped like turtles' heads. Chelone is a carefree, fall-blooming perennial that does not handle excessive dry heat well. It is perfect for a damp area in your garden.

    Turtlehead is not unruly. It grows in a dense clump with attractive foliage and red, pink, or white flowers that bloom for weeks. You can prune it lightly to shape it in late fall or spring. It is hardy throughout much of the country, growing in zones 2 through 9.
