25 Perennials Cut Back More Blooms to Try in Your Garden This Season
25 Perennials Cut Back More Blooms to Try in Your Garden This Season
If you’ve ever hesitated with pruning shears in hand, wondering whether cutting back your perennials will help or hurt them, you’re not alone. The truth is, a lot of our favorite garden perennials actually respond to a good trim with fresh growth and a second (sometimes third) round of flowers. This practice, often called deadheading or cutting back, redirects the plant’s energy away from seed production and into new blooms and healthier foliage. Below are 25 perennials that genuinely reward you for picking up those shears this season.
Coneflower
Echinacea, better known as coneflower, is one of those tough-as-nails prairie natives that just keeps giving. Its daisy-like blooms in purple, pink, orange, or white attract bees and butterflies all summer long. Plant it in full sun with well-draining soil, and it’ll tolerate drought once established. Cutting back spent blooms encourages a second flush and keeps the plant looking tidy instead of leggy. It thrives in USDA zones 3 through 9 and is fairly deer resistant, which is always a bonus.
Salvia
Salvia is practically famous among gardeners for its rebloom potential. After the first wave of spiky purple or blue flowers fades, shear the plant back by about a third and you’ll often see new flower spikes within a few weeks. It likes full sun, average soil, and doesn’t fuss much about fertilizer. Hardy in zones 4 through 9, salvia is also a pollinator magnet and pairs beautifully with ornamental grasses.
Shasta Daisy
Classic and cheerful, the Shasta daisy brings that old-fashioned garden charm with its white petals and yellow centers. Deadhead spent flowers regularly and you’ll extend the bloom season well into fall. It prefers full sun and well-draining soil, and it’s not particularly picky about pH. Growing in zones 5 through 9, this perennial divides easily every few years, which is a great way to get more plants for free.
Catmint
Catmint is one of those plants I genuinely think every garden needs. Its lavender-blue spikes bloom for weeks, and once they start looking tired, a hard shearing back to about half its height triggers a fresh round of flowers almost immediately. It’s drought tolerant, deer resistant, and thrives in full sun with lean, well-draining soil. Zones 3 through 8 suit it well, and bees absolutely adore it.
Black-Eyed Susan
This native beauty brings warm gold and brown tones to the late-summer garden. Deadheading spent blooms keeps black-eyed Susan flowering longer and prevents it from putting all its energy into seed heads (unless you want to leave some for the birds in fall). It’s happy in full sun, tolerates average to poor soil, and is hardy from zones 3 to 9. Fast-growing and low-maintenance, it’s a great pick for beginner gardeners.
Bee Balm
Bee balm’s shaggy, firework-like blooms are a hummingbird favorite. Cutting back after the first flowering not only encourages more flowers but also helps prevent powdery mildew, which this plant can be prone to in humid conditions. It prefers full sun to partial shade and consistently moist, well-draining soil. Hardy in zones 4 through 9, it spreads by rhizomes, so give it room or plan to divide it occasionally.
Yarrow
Yarrow’s flat-topped flower clusters come in shades of yellow, pink, and white, and they hold up beautifully in dried arrangements too. Trimming back the first round of blooms often produces a second flush before frost. This perennial is remarkably drought tolerant and prefers full sun with well-draining, even sandy, soil. Zones 3 through 9 work well, and it’s a low-fuss choice for gardeners who forget to water sometimes (no judgment).
Veronica
Also called speedwell, veronica produces tall, slender spikes of blue, purple, or pink flowers. Once the spikes fade, cut them back to the basal foliage and you’ll often get a second bloom cycle. It likes full sun to light shade and well-draining soil that isn’t too rich. Hardy in zones 3 through 8, veronica is a nice companion for coneflowers and daylilies in a mixed border.
Phlox
Garden phlox brings that classic cottage-garden fragrance and color in midsummer. Deadheading spent flower clusters prevents unwanted self-seeding (which can lead to less vigorous offspring) and often pushes out smaller secondary blooms. It prefers full sun with good air circulation to avoid powdery mildew, and moist, well-draining soil. Zones 4 through 8 are ideal, and it’s a favorite of butterflies.
Threadleaf Coreopsis
With its fine, feathery foliage and cheerful yellow blooms, threadleaf coreopsis is a workhorse in the perennial border. A light shearing after the first bloom flush keeps it compact and encourages continuous flowering through summer. It thrives in full sun and well-draining soil, even sandy or rocky conditions. Hardy in zones 4 through 9, it’s remarkably drought tolerant once established.
Lavender
Lavender isn’t just fragrant and beautiful — it also benefits from a trim after its main bloom period, which can encourage a smaller second flush in milder climates. It absolutely needs full sun and well-draining, slightly alkaline soil; soggy roots are its biggest enemy. Hardy in zones 5 through 9 depending on variety, lavender is drought tolerant and deer resistant, making it a great low-maintenance border plant.
Dianthus
Also known as pinks, dianthus produces clove-scented flowers in shades of pink, red, and white. Regular deadheading keeps this compact perennial blooming from late spring well into fall. It prefers full sun and well-draining, slightly alkaline soil. Zones 3 through 9 suit most varieties, and dianthus works wonderfully in rock gardens or as a border edging plant.
Blanket Flower
Gaillardia, or blanket flower, offers warm red-and-yellow blooms that look like tiny sunsets. Deadheading spent flowers is key to keeping this one blooming continuously through the heat of summer. It loves full sun and thrives in poor, well-draining soil — in fact, overly rich soil can make it floppy. Hardy in zones 3 through 10, it’s drought tolerant and a favorite among pollinators.
Delphinium
Delphinium’s towering flower spikes are a showstopper in cottage gardens, though it does ask a bit more of you. Cutting the flower stalk down to the basal foliage after blooming can often trigger a second, smaller bloom in late summer. It prefers full sun to partial shade in cooler climates and rich, well-draining soil with consistent moisture. Zones 3 through 7 are best, since delphinium struggles in intense heat.
Lupine
Lupine’s tall spires of pea-like flowers come in a rainbow of colors and add real vertical drama to a border. Cutting back the main flower spike after it fades sometimes encourages smaller side shoots to bloom. It prefers full sun to partial shade and slightly acidic, well-draining soil. Hardy in zones 4 through 8, lupine is a nitrogen fixer, so it actually improves the soil around it over time.
Columbine
Columbine’s delicate, bell-shaped flowers dance above ferny foliage in spring. While it’s mostly a one-time spring bloomer, cutting back spent flower stalks can occasionally coax out a few more blooms and definitely keeps the plant looking neater. It grows well in partial shade with moist, well-draining soil. Zones 3 through 9 suit it, and it self-seeds readily if you let a few seed heads mature.
Lady’s Mantle
This perennial is grown as much for its scalloped, dew-catching foliage as for its chartreuse flower sprays. Shearing back after flowering not only tidies the plant but can spark fresh foliage growth and occasional rebloom. It prefers partial shade and consistently moist, well-draining soil. Hardy in zones 3 through 8, lady’s mantle makes a lovely edging plant along shaded pathways.
Geranium (Hardy Cranesbill)
Not to be confused with the annual pelargonium, hardy geranium is a true perennial with a long bloom season. Shearing the whole plant back partway through summer often results in fresh foliage and a strong rebloom by early fall. It does well in full sun to partial shade and average, well-draining soil. Zones 4 through 8 are typical, and it makes a fantastic ground cover between larger perennials.
Astilbe
Astilbe’s feathery plumes bring texture and soft color to shade gardens. While reblooming isn’t its strong suit, deadheading spent plumes redirects energy into stronger root and foliage growth for next year. It thrives in partial to full shade with consistently moist, rich soil. Hardy in zones 4 through 9, astilbe pairs beautifully with hostas and ferns in a woodland-style bed.
Peony
Few perennials draw as much admiration as peonies in full bloom. Although they typically flower once, deadheading spent blooms promptly prevents the plant from wasting energy on seed pods and supports better blooms next year. Peonies need full sun and rich, well-draining soil, and they’re famously long-lived once established. Zones 3 through 8 are ideal, and they genuinely seem to improve with age — some peonies outlive the gardeners who planted them.
Daylily
Daylilies are practically indestructible, and many reblooming varieties respond well to having spent flower stalks cut down to the base. This tidies the clump and channels energy toward new buds. They tolerate full sun to partial shade and adapt to nearly any well-draining soil. Hardy in zones 3 through 10, daylilies are drought tolerant and about as forgiving as perennials get.
Penstemon
Also called beardtongue, penstemon produces tubular flowers loved by hummingbirds. Cutting back the first bloom spikes once they fade often results in a lighter second bloom later in the season. It prefers full sun and lean, well-draining soil — it actually dislikes overly fertile ground. Zones 3 through 9 work for most varieties, and it’s a solid drought-tolerant choice for xeriscaped gardens.
Sea Thrift
Sea thrift, or armeria, forms neat grassy mounds topped with round pink or white flower clusters. Deadheading spent blooms consistently keeps this compact perennial flowering for months. It thrives in full sun and gritty, well-draining soil, tolerating sandy or rocky conditions with ease. Hardy in zones 4 through 8, it’s a charming choice for rock gardens or border edges.
Scabiosa
Known as pincushion flower for its unique bloom shape, scabiosa is one of the most reliable rebloomers on this list. Regular deadheading practically guarantees continuous flowering from late spring through the first frost. It prefers full sun and well-draining, slightly alkaline soil. Zones 3 through 9 suit it well, and its long stems make it excellent for cutting gardens.
Blue Star (Amsonia)
Amsonia offers soft blue star-shaped flowers in spring and stunning golden foliage in fall, making it a two-season standout. While reblooming isn’t really its thing, a light trim after flowering keeps the mound-shaped foliage dense and attractive for the rest of the season. It grows well in full sun to partial shade and adapts to average, well-draining soil. Hardy in zones 3 through 9, it’s a low-maintenance native that pairs nicely with ornamental grasses.
Cutting back perennials isn’t about being ruthless with your garden — it’s more like giving your plants a gentle nudge to keep doing what they do best. A pair of sharp, clean pruning shears and a little attention to spent blooms throughout the season can genuinely extend your color from late spring all the way into fall. Try picking a few of these for your own beds, and don’t be afraid to experiment with timing — every garden and climate responds a little differently.
