Perennials are the backbone of any thriving garden, valued for their reliability, color, and ability to return year after year.
But while many perennials bloom only once in a season, some superstars deliver a bonus for gardeners: multiple blooming periods throughout the summer.
These repeat bloomers transform a garden into a season-long display of color and texture, providing fresh beauty week after week.
They’re also essential for pollinators, as repeated blooms mean continuous nectar and pollen for bees, butterflies, and hummingbirds.
If you want your garden to look vibrant and full from June through September (and even beyond), these seven perennials should be on your must-plant list.
1. Daylilies (Hemerocallis)
Why They’re Ideal
Daylilies are among the most cherished perennials for a reason. Each individual bloom may last only a day, but the plant continually produces new buds throughout summer.
And newer cultivars, called reblooming daylilies, extend this floral display into late summer or early fall.
Varieties like:
- ‘Stella de Oro’ – Famous golden-yellow rebloomer.
- ‘Happy Returns’ – Soft yellow blooms, perfect for borders.
- ‘Rosy Returns’ – Pink blossoms, compact habit.
Their wide palette of colors, from lemon yellow to deep red and purple, makes daylilies perfect for virtually any garden theme.
Growing Tips:
- Light: Full sun to light shade (at least 6 hours of sun).
- Soil: Well-draining soil enriched with compost.
- Water: Moderate, especially in dry spells.
- Maintenance: Deadhead spent blooms daily and remove spent scapes (flower stalks) to encourage further flowering. Divide clumps every 3-5 years to maintain plant vigor and flowering performance.
Great For:
- Borders and mass plantings.
- Hillsides and erosion control.
- Low-maintenance perennial gardens.
2. Shasta Daisies (Leucanthemum × superbum)
Why They’re Ideal
Few flowers say “summer” like Shasta daisies. Their crisp white petals and sunny yellow centers create a fresh, cheerful look in garden beds.
These hardy perennials bloom generously in early summer and can produce a second flush if deadheaded promptly.
Modern varieties like:
- ‘Becky’ – Tall, sturdy stems, long blooming.
- ‘Snowcap’ – Compact and perfect for small spaces.
- ‘Crazy Daisy’ – Frilly, double-petaled blooms.
Shasta daisies make outstanding cut flowers, adding longevity and brightness to floral arrangements.
Growing Tips:
- Light: Full sun.
- Soil: Well-draining soil, moderately fertile.
- Water: Moderate; avoid soggy soil.
- Maintenance: Deadhead faded blooms promptly to trigger reblooming. Trim plants back lightly after the first flush. Divide every 2-3 years to rejuvenate.
Great For:
- Cottage gardens.
- Cutting gardens.
- Sunny borders.
3. Coreopsis (Coreopsis spp.)
Why They’re Ideal
Coreopsis, also known as tickseed, offers an extended summer performance with bright, daisy-like blooms in shades of yellow, gold, red, and pink.
These rugged perennials bloom for weeks and bounce back for another round if trimmed back.
Outstanding varieties include:
- ‘Moonbeam’ – Pale yellow, fine-textured foliage.
- ‘Zagreb’ – Golden-yellow, compact habit.
- ‘Mercury Rising’ – Deep burgundy blooms.
They’re drought-tolerant, easy to grow, and beloved by pollinators.
Growing Tips:
- Light: Full sun.
- Soil: Well-drained; tolerates poorer soils.
- Water: Moderate; drought-tolerant once established.
- Maintenance: Deadhead regularly to keep flowers coming. Shear plants back by half after the first big flush to promote a second bloom cycle.
Great For:
- Wildflower meadows.
- Pollinator gardens.
- Low-maintenance landscaping.
4. Catmint (Nepeta)
Why They’re Ideal
Catmint is a dreamy addition to sunny borders. Its fragrant gray-green foliage and clouds of lavender-blue flowers make it a favorite for cottage gardens and pollinator plantings.
Though its first bloom flush is the showiest, a mid-season trim leads to another robust wave of blooms.
Top performers include:
- ‘Walker’s Low’ – Long bloom time, soft lavender color.
- ‘Cat’s Meow’ – Tidy mounding habit, ideal for edges.
- ‘Junior Walker’ – Compact size for smaller gardens.
Growing Tips:
- Light: Full sun to light shade.
- Soil: Well-drained soil; tolerates dry conditions.
- Water: Low to moderate; drought-tolerant.
- Maintenance: Shear plants back by one-third after the first flush to encourage reblooming. Avoid overfertilizing, which can lead to floppy growth.
Great For:
- Pathway borders.
- Rock gardens.
- Pairing with roses and other summer perennials.
5. Salvia (Salvia nemorosa)
Why They’re Ideal
Salvia, or perennial sage, brings vibrant color and texture with spiky blooms ranging from indigo to pink and white.
Its aromatic foliage deters deer and rabbits while attracting bees and hummingbirds.
Excellent reblooming varieties:
- ‘May Night’ – Deep violet-blue, award-winning cultivar.
- ‘Caradonna’ – Elegant dark stems, purple spikes.
- ‘Rose Marvel’ – Bright pink blooms on a compact plant.
Growing Tips:
- Light: Full sun.
- Soil: Well-drained, average to slightly dry soil.
- Water: Moderate; drought-tolerant when established.
- Maintenance: Cut back faded spikes after blooming to stimulate fresh growth and more flowers. Divide every few years if clumps become woody.
Great For:
- Pollinator-friendly gardens.
- Mediterranean-style plantings.
- Sunny borders.
6. Veronica (Veronica spicata)
Why They’re Ideal
Also known as speedwell, Veronica offers slender, upright spikes of color ranging from blue to purple, pink, and white.
This reliable perennial starts blooming in early summer and can produce more flowers if sheared back after its first flush.
Popular types:
- ‘Royal Candles’ – Vibrant blue spikes, compact habit.
- ‘Icicle’ – Pure white flowers for contrast.
- ‘Red Fox’ – Bright rosy-pink blooms.
Veronica’s neat shape and continuous flowering make it a perfect companion plant for other perennials.
Growing Tips:
- Light: Full sun to part shade.
- Soil: Well-drained, fertile soil.
- Water: Regular; keep soil evenly moist but not soggy.
- Maintenance: Trim faded flower spikes to promote a second bloom. Mulch lightly to keep roots cool in hot summer.
Great For:
- Mixed perennial borders.
- Butterfly gardens.
- Cutting gardens.
7. Echinacea (Echinacea purpurea)
Why They’re Ideal
Echinacea, or coneflower, is famous for its daisy-like blooms with prominent central cones.
Available in colors beyond the traditional purple – including pink, white, orange, and yellow – modern varieties offer extended bloom periods and multiple flushes of flowers.
Favorite varieties:
- ‘Magnus’ – Classic pink-purple blooms.
- ‘PowWow White’ – Crisp white petals.
- ‘Cheyenne Spirit’ – Mixed vibrant shades on one plant.
Echinacea is not only stunning but highly beneficial for pollinators and songbirds.
Growing Tips:
- Light: Full sun.
- Soil: Well-drained; tolerates poor soils.
- Water: Moderate; drought-tolerant once established.
- Maintenance: Deadhead faded blooms for extended flowering. Leave late-season cones for birds and winter interest.
Great For:
- Prairie-style gardens.
- Pollinator habitats.
- Cutting gardens.
How to Encourage Repeat Blooms in Perennials
For perennials to bloom repeatedly, a bit of maintenance makes all the difference:
- Deadheading: Remove spent blooms to stop seed production and stimulate new flower buds.
- Shearing: Some perennials respond well to being cut back by a third or half after flowering.
- Regular Watering: Even drought-tolerant perennials bloom better with consistent moisture.
- Balanced Feeding: Fertilize lightly after the first bloom flush.
- Proper Spacing: Good air circulation helps prevent diseases that can halt flowering.
Why Choose Repeat-Blooming Perennials?
Growing perennials that bloom multiple times:
- Extends garden color for months.
- Supports pollinators with continuous nectar.
- Reduces maintenance costs and annual replanting.
- Creates dynamic landscapes that evolve throughout the season.
A garden that blooms from the first days of summer until autumn’s chill is a sight to behold – and it’s entirely achievable with the right perennial choices.
By planting daylilies, Shasta daisies, coreopsis, catmint, salvia, Veronica, and echinacea, you ensure vibrant color, structure, and wildlife interest all season long.
Give these hardworking plants a home in your garden, and enjoy a landscape that’s alive with beauty for months on end!
