Plant These 10 Flowers in August for Stunning Fall Blooms

When summer starts to wind down, many gardeners assume it’s too late to add new flowers to the garden. But here’s the good news—you’ve still got time! By planting certain flowers in August, you can set yourself up for a vibrant, colorful display just as autumn arrives. These blooms will not only brighten your garden but also provide nectar for late-season pollinators.
So grab your trowel and gloves—here are 10 fall-blooming flowers you should plant in August for a breathtaking autumn show.
- Chrysanthemums (Mums)
If there’s one flower that screams fall, it’s mums. Available in a rainbow of colors—bronze, orange, yellow, red, and purple—these classic favorites thrive when planted in August. Give them full sun, rich soil, and regular watering, and you’ll be rewarded with cheerful blooms that can last right into early frost.
Pro tip: Pinch back the tips when planting to encourage bushier growth and more blooms.
- Pansies
Pansies are cool-season champs that can take a little chill. Plant them in August and they’ll settle in before cooler weather hits, giving you plenty of flowers through fall and even into winter in mild climates. Their cheerful faces in shades of purple, yellow, and blue make them perfect for garden beds, pots, and borders. - Marigolds
Fast-growing and easy, marigolds are a must for late-summer planting. In August, they sprout quickly and bloom through fall, adding fiery shades of gold, orange, and red. They’re also natural pest repellents, keeping your garden healthier during the transition to cooler weather. - Calendula
Sometimes called “pot marigold,” calendula thrives in cooler weather and puts out cheery yellow-orange blooms. Plant them in August, and they’ll flower until frost. Not only are they pretty, but calendula petals are edible and can be used to brighten salads or teas. - Coneflowers (Echinacea)
If you want a hardy perennial that won’t let you down, coneflowers are it. Planting them in August gives them just enough time to root before fall. Their daisy-like blooms in purples, pinks, and whites attract butterflies and bees, while their seed heads feed birds later in the season. - Asters
Asters are late-bloomers that bring splashes of purple, pink, and white to the autumn garden. They’re pollinator magnets, especially for butterflies looking for a last sip of nectar before migration. Plant them now, and they’ll settle in just in time for their natural fall bloom. - Black-Eyed Susans (Rudbeckia)
Tough, dependable, and sunny, black-eyed Susans thrive when planted in August. Their golden petals with dark centers are the perfect contrast to autumn foliage. They bloom well into fall and often return year after year with minimal care. - Dianthus
Fragrant and compact, dianthus adds a touch of charm to fall borders and containers. Plant them in August for blooms in shades of pink, red, and white. Many varieties will overwinter and bloom again in spring, making them a gardener’s double win. - Violas
Similar to pansies but smaller, violas are another great choice for August planting. They bloom quickly and last through fall, providing color when many summer flowers fade. Their delicate blossoms thrive in cooler weather, making them perfect companions for other fall bloomers. - Goldenrod
Often mistaken as a weed, goldenrod is a stunning fall bloomer with tall, golden flower spikes. Plant it in August for a bold late-season display that attracts bees, butterflies, and even migrating monarchs. It pairs beautifully with asters and coneflowers in a natural-style garden.
Tips for Planting Flowers in August
Choose the right location: Most fall-blooming flowers thrive in full sun, so pick a bright spot.
Improve soil: Mix in compost or organic matter to boost nutrients and drainage.
Water consistently: August heat can still stress young plants, so keep the soil evenly moist.
Deadhead blooms: Removing spent flowers encourages longer flowering and healthier plants.
Think containers: If your garden beds are full, many of these flowers thrive in pots and window boxes.
