🌼 12 Full Sun Perennials Flowers That Bloom All Summer
These tried-and-true perennials don’t just survive the summer heat — they thrive in it, offering long-lasting blooms, drought tolerance, and plenty of visual interest. Here are 12 exceptional choices to bring color and vitality to your sunny garden beds.
🌸 1. Daylilies (Hemerocallis)
Why You’ll Love Them:
- Prolific bloomers with trumpet-shaped flowers in every color imaginable
- Drought-tolerant and low-maintenance — perfect for busy gardeners
- Ideal for borders, cutting gardens, or mass plantings
Daylilies are a staple in sun-filled landscapes for good reason. These adaptable perennials can bloom for weeks, especially if you choose reblooming varieties. Their tall, arching foliage adds movement and softness to your garden, and the flowers attract pollinators like bees and butterflies. They thrive in poor soil, making them a versatile option even in tough conditions.
🌼 2. Tall Phlox (Phlox paniculata)
What Makes It Special:
- Bold clusters of fragrant blooms from mid to late summer
- Available in a range of colors including bicolors
- Great for containers, borders, or front-of-home beds
Tall phlox is a garden classic that delivers both scent and style. These full sun perennials flowers create vertical drama and pair well with other summer bloomers. As a bonus, their strong fragrance helps attract butterflies and hummingbirds. For the healthiest growth, plant them in well-drained soil and space them to encourage airflow, reducing the risk of mildew.
🌼 3. Coneflowers (Echinacea)
Garden Benefits:
- Sturdy, upright habit with daisy-like flowers in rich purples, pinks, and whites
- Loved by pollinators and birds alike
- Drought-tolerant and low-fuss
Coneflowers are the poster child of full sun perennials flowers. Not only are they eye-catching, but their seed heads also provide food for birds in the fall. Varieties now range from the classic purple to bright oranges, yellows, and even doubles — giving you ample choices for every garden theme. They make excellent companions for ornamental grasses and black-eyed Susans.
🌺 4. Hollyhocks (Alcea rosea)
Tall and Striking:
- Towering spikes reach up to 7 feet tall
- Deer-resistant and pollinator-friendly
- Perfect for fences, backdrops, or cottage-style gardens
Nothing says “cottage charm” like hollyhocks. These vertical bloomers shine when planted along walls or garden structures, where their colorful blooms can stand tall and sway in the breeze. Hollyhocks thrive in full sun and well-drained soil, and while they’re often biennials, many modern varieties act like short-lived perennials, blooming reliably for several seasons.
🌺 5. Hardy Geraniums (Geranium sanguineum and others)
Why Gardeners Adore Them:
- Extended bloom period from spring to fall
- Low-growing, deer-resistant, and drought-tolerant
- Great as ground cover, in borders, or trailing from containers
Hardy geraniums, often called “cranesbills,” are the unsung heroes of sunny gardens. These compact perennials offer a carpet of finely cut foliage and vibrant blooms in shades of pink, purple, blue, and white. They’re incredibly resilient, requiring minimal maintenance once established. Ideal for sunny rock gardens, borders, or the edges of raised beds, they’re a must-have for gardeners who want beauty with zero fuss.
🌻 6. Coreopsis (Coreopsis verticillata, C. grandiflora)
Standout Qualities:
- Cheerful, daisy-like flowers in golds, reds, and pinks
- Long bloom season and loved by butterflies
- Excellent for cutting gardens or mass planting
Coreopsis brings a splash of sunshine to any spot in the garden. These full sun perennials flowers bloom profusely from early to late summer, often into fall with deadheading. Their fine, thread-like foliage contrasts beautifully with broader-leaved perennials. Whether you choose compact dwarf varieties or airy, taller cultivars, coreopsis creates a joyful and enduring display.
✨ 7. Astrantia (Astrantia major)
Elegant and Unique:
- Starburst-like flowers add sparkle and structure
- Blooms steadily from early summer to fall
- Thrives in sun or partial shade
Astrantia, also known as masterwort, adds an enchanting, almost glittery quality to full sun beds. Their intricate, pincushion-style blooms sit atop wiry stems, offering contrast and texture. These flowers are favorites among floral designers and bees alike. While often associated with woodland gardens, many varieties handle full sun with adequate moisture, making them a rare gem for mixed perennial borders.
🔥 8. Heleniums (Helenium autumnale and hybrids)
Fiery Summer Performers:
- Abundant blooms in warm red, orange, and gold tones
- Long flowering season from summer through early fall
- Sturdy stems ideal for borders or bouquets
Nicknamed “sneezeweed” (though they don’t trigger allergies), heleniums are vibrant powerhouses. Their richly colored, daisy-like flowers create an explosion of color that stands out in any full sun planting. These perennials are especially valuable for late-summer gardens, bridging the seasonal gap before fall. Plus, they attract a flurry of pollinators, from butterflies to bees.

Tropical Flair with Long Bloom Time:
- Delicate, orchid-like flowers in vibrant hues
- Excellent in containers, garden beds, and bouquets
- Blooms persist from early summer to fall with regular deadheading
Often seen in florist arrangements, alstroemeria brings exotic charm to home gardens. Despite their delicate appearance, these full sun perennials flowers are surprisingly hardy in zones 5–9. They thrive in sunny locations with well-drained soil, producing dozens of blooms that last for weeks in the garden—or the vase. Their long stems and colorful petals make them a standout for cutting gardens and patio displays alike.
🔥 10. Red Hot Pokers (Kniphofia uvaria)
Bold and Unforgettable:
- Striking spikes of tubular flowers in fiery tones
- Loved by hummingbirds and butterflies
- Adds vertical interest and exotic texture to borders
Red hot pokers, or torch lilies, are sure to turn heads. Their torch-like blooms range from bright orange and red to buttery yellow, offering a dramatic focal point in sunny beds. These perennials are not only deer-resistant but also thrive in dry, sandy soils. Pair them with ornamental grasses or echinacea for a dynamic, drought-tolerant garden design.
🌼 11. Shasta Daisies (Leucanthemum x superbum)
Classic Charm, Modern Edge:
- White petals with golden centers add timeless elegance
- Low-maintenance and deer-resistant
- Great for borders, cottage gardens, and floral arrangements
No list of full sun perennials flowers is complete without the cheerful Shasta daisy. These sturdy bloomers provide a crisp, clean look that works in both traditional and contemporary gardens. Their long stems and vibrant blooms make them ideal for cutting, and they blend seamlessly with other summer favorites like black-eyed Susans or salvia. Deadhead regularly to encourage continuous blooming.
🌸 12. Cinquefoil (Potentilla spp.)
Small but Mighty:
- Compact growth with saucer-shaped blooms

- Perfect for sunny borders, foundation plantings, or rock gardens
Cinquefoil delivers big benefits in a small package. These low-maintenance shrubs or perennials boast a long flowering period, often from late spring into fall.
