A few years ago, I was tired of my garden looking beautiful for a few weeks and then turning into a sea of green. I wanted color that lasted all season. I started researching plants that bloom for months, not weeks, and my garden has never been the same.
Now I have flowers from early spring right through the first frost. Here are the best long-blooming flowers that will keep your garden colorful all season long.
Why Choose Long-Blooming Flowers?
Long-blooming flowers are the overachievers of the plant world. They show up early, stick around for months, and ask for very little in return. Choosing them for your garden is cost-effective and significantly reduces maintenance. Varieties that offer multiple seasons of interest mean fewer bare patches and no more weekly trips to the plant nursery.
The simple rule: Look for plants that either bloom continuously or rebloom after deadheading. With the right choices, you can have color from spring to frost.
Long-Blooming Perennials
Perennials come back year after year, saving you time and money. While many perennials only bloom for 3-4 weeks, breeders have developed varieties that bloom for months.
1. Hardy Geranium (Cranesbill)
Hardy geraniums are low-growing plants that bloom in blue, lavender, or pink. They start in late May and bloom sporadically for most of the season. Rozanne Cranesbill is often called the “perennial annual” because it blooms continuously from late spring through to fall.
Best varieties: ‘Rozanne’, ‘Azure Rush’, ‘Johnson’s Blue’.
2. Catmint (Nepeta)
Catmint produces blue flowers for nearly two months in May and June, then flowers again until frost after a cutback. It is drought-tolerant, pollinator-friendly, and thrives in hot, dry conditions.
Best varieties: ‘Cat’s Meow’, ‘Cat’s Pajamas’, ‘Blue Ice’.
3. Meadow Sage (Salvia)
Salvia blooms with purple flower spikes in May and June, then usually blooms again in late summer if the spent blooms are snipped off. It’s a heat- and drought-tough, winter-hardy type that gives you three or four months of flowers.
Best varieties: ‘May Night’, ‘Caradonna’, ‘Marcus’.
4. Betony (Stachys)
This underrated plant produces pink-lavender flower spikes for months from June into October. It does well in full sun to part shade.
Best varieties: ‘Hummelo’, ‘Summer Crush’.
5. Tickseed (Coreopsis)
Tickseed produces little buttony blooms of golden yellow starting in June. Some of the best varieties can bloom for nearly four months. It blooms from early summer all the way to the first frost.
Best varieties: ‘Zagreb’, ‘Golden Gain’.
6. Anise Hyssop (Agastache)
Anise hyssop produces licorice-scented flower spikes of blue, lavender, and pastel blends that start in June and last until September. Pollinators love this plant.
7. White Corydalis (The Longest Blooming Perennial of All)
This is the champion of long-blooming perennials. White corydalis is up and blooming by mid-May and sails through the summer into October without stopping. It even keeps blooming through light snow. One expert calls it the “bloomingest perennial ever”.
Best variety: Pseudofumaria alba (formerly Corydalis ochroleuca).
8. Yellow Corydalis
Yellow corydalis starts blooming a few weeks earlier than bleeding hearts and continues just as long, into October.
Best variety: Pseudofumaria lutea (formerly Corydalis lutea).
9. Bleeding Heart (Dicentra)
Better clones of the western bleeding heart and its hybrids are remarkably long-blooming, blooming massively in late May/early June, and then sporadically right through summer and early fall.
Best varieties: ‘Luxuriant’, ‘Adrian Bloom’, ‘Aurora’.
10. Black-Eyed Susan (Rudbeckia)
Black-Eyed Susans are cheerful golden-yellow flowers with dark centers that bloom from midsummer to fall. They are easygoing, and pollinators love them. They last all summer long.
11. Coneflower (Echinacea)
Coneflowers are available in a range of colors, but most commonly seen in pinks and purples. They bloom from mid-summer into fall. Once settled in, they shrug off drought, don’t mind poor soil, and bring in bees, butterflies, and hummingbirds.
12. Yarrow
Yarrow has fern-like leaves and clusters of tiny blooms in yellow, white, pink, or purple. It can flower for a long period of time. It starts blooming in late spring and keeps going through summer.
13. Daylily (Stella D’Oro)
Stella D’Oro daylilies flower almost continuously from late spring through fall, providing months of color and charm. It’s a sunny yellow lily that adds a joyful infusion to any garden.
14. Lavender
Lavender has long-lasting, delicate, charming purple flowers that open in early spring and flourish from spring until the summer heat arrives, then rest and sometimes return in fall.
15. Russian Sage
Russian Sage has airy lavender-blue flowers and silvery, fragrant leaves. It keeps blooming from midsummer into fall. It thrives in hot, dry spots.
16. Shasta Daisy
Shasta daisies are the classic white and yellow daisies. They often bloom from early summer to early fall, adding a bright spot wherever you put them.
17. Bee Balm (Monarda)
Bee balm produces scarlet red blooms from June through August. The flowers are like little fireworks on top of sturdy stems, and they are a magnet for hummingbirds and butterflies.
18. Hydrangea (Paniculata)
Panicle hydrangeas like ‘Limelight’ offer long-lasting blooms that run from mid-summer through to late fall.
19. Knock Out Roses
Knockout roses are bright, beautiful, and a cinch to grow. They add nonstop color to your garden with minimal effort.
20. Catmint (Nepeta)
This low-maintenance perennial produces bright purple blooms that last from late spring through to fall.
Long-Blooming Annuals
Annuals only last one growing season, but they are known for their showy, colorful blooms and often bloom continuously until frost.
21. Zinnias
Zinnias can fill a garden bed with wall-to-wall color. Once the soil warms, they bloom continually until the first frost.
22. Alyssum
Alyssum blooms non-stop for a fresh, animated look, and in certain climates, it can bloom all year long. Their tufted forms spread and spill dainty blossoms over border edging or containers.
23. Lantana
Lantana is a virtually indestructible plant that thrives in hot, dry sun. It blooms all summer and is loved by hummingbirds and pollinators.
24. Petunia
Petunias are a summer favorite with non-stop flowering if regularly deadheaded.
25. Begonia
Begonias thrive in both sun and shade with blooms lasting from spring to autumn.
26. Marigolds
Marigolds are known for their showy, colorful blooms and bloom all summer.
27. Dahlia
Dahlias flower from summer into autumn, providing months of color with regular deadheading.
28. Salvia (Annual Varieties)
Many annual salvias produce tall, boldly colored flowers and bloom from spring to fall.
Tips for Extending Blooms
Deadhead Regularly
Removing spent flowers encourages plants to produce more blooms instead of going to seed.
Cut Back After the First Flush
For plants like catmint and salvia, cutting them back after the first bloom encourages a second flush of flowers.
Feed Your Plants
Regular feeding with a bloom-boosting fertilizer supports continuous flowering.
Water Consistently
Consistent moisture, especially during dry spells, keeps plants healthy and blooming.
Choose the Right Spot
Most long-blooming plants need full sun (at least 6 hours) to produce their best display.
