Whether you’re looking to fill your garden with daisy-like flowers, bright pink blossoms, or the striking texture of purple fountain grass, there’s a perennial to suit every garden style.
In this guide, we’ll explore seven standout fall-blooming perennials that will keep your garden colorful and lively right through to the first frost. From the cheerful Blanket Flower to the majestic Fountain Grass, these perennials will ensure your garden remains a visual delight well into the autumn months.
7 Fall Blooming Perennials for a Colorful Garden
1. Blanket Flower
The Blanket Flower, or Gaillardia, is a true showstopper in the autumn garden. Known for its vibrant, warm hues of red, orange, and yellow, this perennial blooms multiple times from early summer well into the fall, with its peak bloom time typically in late summer to early fall. It’s like having a sunset in your orchard, with its daisy-like flowers adding a splash of color that complements the season’s changing leaves. These flowers bloom in single or double forms, depending on the variety, and they’re incredibly attractive to butterflies, making them a fantastic choice for pollinator-friendly gardens.
Blanket Flowers have a mounding habit, typically reaching a height of 1 to 2 feet with a spread of about the same. They thrive in loose soil, making them ideal for gardens in hotter, drier climates. These perennials prefer full sun exposure and can handle poor soil conditions, so they’re perfect for low-maintenance gardeners. A bonus? These perennials are deer-resistant, so you won’t have to worry about your hard work being nibbled away by unwanted visitors.
2. Chrysanthemum
No outer yard is complete without the classic Chrysanthemum, often called mums. These iconic fall bloomers come in a wide range of colors, from bright pinks and purples to warm oranges and deep reds. Chrysanthemums are known for their dense, bushy growth and their ability to produce clusters of flowers that bloom profusely in the fall, usually from early fall until the first frost.
With varieties that offer single or double flowers, mums are versatile and can be used in mixed borders, containers, or mass plantings for a bold impact.
Chrysanthemums can grow to heights of 1 to 3 feet, depending on the variety, with a spread of up to 2 feet. They prefer permeable soil and full sun, though they can tolerate partial shade in hotter climates. Plant them in mid-summer to allow them time to establish before they start blooming in late summer and fall. Mums are also great for attracting pollinators, providing a late-season feast for butterflies and bees as they prepare for the cooler months ahead.
3. Boltonia
Boltonia, also known as false aster, is a vigorous fall-blooming perennial that adds height and texture to your garden. This herbaceous perennial produces clouds of tiny flowers that resemble daisies, with colors ranging from white to light pink. These flowers bloom from late summer into the fall, providing a soft, airy effect that contrasts beautifully with the bolder colors of other fall bloomers. Boltonia is particularly well-suited to mixed borders and can reach heights of up to 6 feet, with a spread of 3 to 4 feet, making it a great choice for the back of flower beds.
It thrives in full sun and light soil but can tolerate clay soil as well. It has an upright habit and is highly drought-tolerant once established, making it a resilient choice for gardens that experience dry spells.
4. Black-eyed Susan
Black-eyed Susans (Rudbeckia hirta) are a staple in any fall garden, thanks to their bright yellow petals and dark, central cones. These cheerful flowers bloom from mid-summer through fall, creating a sunny focal point that’s hard to miss. Black-eyed Susans are incredibly versatile, thriving in full sun and well-drained soil, but they’re also tolerant of partial shade and can adapt to a variety of soil types, including clay. They typically reach a height of 2 to 3 feet with a spread of about 18 inches, giving them a bushy, upright habit.
One of the best things about Black-eyed Susans is their ability to attract butterflies and other pollinators, ensuring your garden remains buzzing with life even as the days grow cooler. They’re also deer-resistant. Plant them in mass groupings for a bold splash of color, or mix them with other fall-blooming flowers like Chrysanthemums and Blanket Flowers for a diverse and eye-catching display.
5. Canna
For a touch of the tropics in your yard, look no further than Canna. With its bold, banana-like leaves and vibrant flowers in shades of red, orange, and yellow, Canna brings a dramatic flair to any landscape. These perennials are perfect for adding height and color to borders and containers, blooming from late summer into the fall. Canna plants thrive in full sun and well-drained soil, but they can also tolerate wetter conditions, making them versatile in various garden settings.
Cannas have a tall, upright habit, often reaching heights of 4 to 6 feet, with a spread of 1 to 2 feet, depending on the variety. They are not only stunning to look at but also incredibly easy to grow. They’re relatively pest-free and can tolerate drought, though they do appreciate regular watering during dry spells. For the best results, plant them in groups to create a lush, tropical look, or use them as a focal point in your garden. Just be sure to lift the rhizomes in colder climates before the first frost, as they aren’t winter-hardy in all hardiness zones.
6. American Blue Vervain
American Blue Vervain (Verbena hastata) is a striking native perennial that adds a touch of wild beauty to your lawn. This plant produces tall spikes of small, purple flowers that bloom from mid-summer through fall, attracting a variety of pollinators, including butterflies and bees. It is particularly well-suited to naturalistic plantings, rain gardens, or mixed borders, where its upright form can add vertical interest.
This perennial thrives in full sun to partial shade and prefers moist soil, making it an excellent choice for areas that stay damp or even flood-prone zones. American Blue Vervain typically reaches heights of 3 to 5 feet, with a spread of 1 to 2 feet, and has an upright, clumping habit. It is also deer-resistant, ensuring that your plants will remain intact despite the presence of hungry wildlife. For a stunning fall display, pair it with other moisture-loving perennials like Joe Pye Weed or Sweet Autumn Clematis.
7. Fountain Grass
Fountain Grass, particularly the popular Purple Fountain Grass (Pennisetum setaceum ‘Rubrum’), is a fantastic addition to any fall garden. With its graceful, arching plumes and reddish-purple foliage, this ornamental grass provides texture and movement, creating a dynamic visual effect. It typically blooms from late summer through fall, with its flower plumes adding vertical interest and a soft, flowing element to your garden design. In warmer regions, it can be a showstopper in mixed borders, containers, or as a standalone specimen.
This grass prefers full sun and well-drained soil and thrives in a variety of garden settings. Fountain Grass has a clumping habit, with heights ranging from 3 to 5 feet and a spread of about 2 to 3 feet. Once established, it is also great as a low-maintenance option for busy gardeners.
To keep your garden vibrant, pair it with other fall bloomers like Chrysanthemums or Blanket Flowers, allowing the rich hues of the grass to complement the bright blossoms of your perennials.
