When we first started planning our sunny garden beds, we quickly realized that not every plant loves the heat. But once we discovered the right full sun perennials, our borders came alive—with color, fragrance, and pollinators buzzing happily all season long.
If you’ve got a sunny patch and want to fill it with flowers that thrive in the heat and come back year after year, this list is for you.
These are my go-to full sun perennials—plants I’ve grown, loved, and recommended time and time again for their toughness, low maintenance, and big visual impact.
1. Coneflower (Echinacea) – A Colorful Showstopper
Coneflowers are reliable workhorses in any sunny garden. Their daisy-like blooms come in purple, pink, orange, and even white—and they’re magnets for bees and butterflies. I plant them in clusters for a strong splash of color, and once they’re established, they barely need a thing.
2. Red Hot Poker (Kniphofia) – A Bold Statement Plant
This one turns heads. Tall spikes in fiery red, orange, and yellow make Red Hot Poker the perfect pick for a bit of drama. I tuck it toward the back of sunny borders for height and structure. It’s tough as nails once settled—just give it well-drained soil and let it do its thing.
3. Hollyhocks (Alcea) – A Cottage Garden Classic
If you’re going for that nostalgic, English cottage vibe, hollyhocks are essential. Their towering blooms bring vertical interest and old-fashioned charm. I love planting them along fences where they can lean a bit and self-seed their way into next year’s display.
4. Black-Eyed Susan (Rudbeckia) – A Vibrant Flower Bed Favorite
You’ll see these cheerful yellow flowers from summer right into fall. Black-Eyed Susans are hardworking, heat-loving plants that ask very little but give so much. They’re perfect for landscape ideas full sun front yards or mixed with grasses for a naturalistic look.
5. Russian Sage (Perovskia) – Hardy and Drought-Tolerant
For soft movement and a splash of lavender-blue, Russian Sage is one of my favorites. It thrives in dry, poor soil and adds a lovely contrast to brighter flowers. I love pairing it with echinacea or blanket flowers for a wild, airy feel.
6. Lavender (Lavandula) – A Deer-Resistant Beauty
Lavender does double duty—it looks beautiful and smells even better. I like to line pathways with it, so every brush releases that soothing scent. It thrives in sunny, dry spots and doesn’t mind a bit of neglect. Plus, deer leave it alone!
7. Shasta Daisy (Leucanthemum) – A Crisp White Accent
Shasta Daisies are like sunshine on a stem. Their clean white petals and yellow centers brighten up any flower bed, and they go with everything. I grow them in big drifts for impact, and with regular deadheading, they just keep blooming.
8. Coreopsis (Tickseed) – A Low-Maintenance Pollinator Magnet
Coreopsis is a joy. Whether it’s yellow, red, or pink, this daisy-like bloomer flowers nonstop and doesn’t fuss about soil. It’s ideal for flower beds low maintenance and adds energy to any spot that needs a little lift.
9. Dwarf Coneflower (Echinacea ‘PowWow Wild Berry’) – Perfect for Containers
All the beauty of coneflowers, but in a neat, compact size! I grow these in containers on the patio where their bold magenta blooms pop against terracotta pots. Just keep them watered and you’ll enjoy color for weeks.
10. Goldenrod (Solidago) – A Burst of Yellow for Late Summer
Goldenrod lights up the garden in late summer when other flowers are winding down. It’s a valuable food source for pollinators and a cheerful addition to seasonal flower beds—especially when paired with asters or ornamental grasses.
11. Dianthus (Dianthus gratianopolitanus) – A Charming Border Plant
Dianthus has a low, mounding habit and delicate, often fragrant flowers that make it perfect for edging paths or filling in tight corners. I love its romantic feel and how it softens hard lines around patios or walkways.
12. Blanket Flower (Gaillardia) – A Heat-Tolerant Powerhouse
These are absolute sun-lovers. With fiery red and yellow petals, blanket flowers bring serious energy to backyard planting ideas landscaping. I plant them in poor soil where others struggle—they always rise to the challenge.
13. Creeping Phlox (Phlox subulata) – A Low-Lying Ground Cover
For a spring carpet of color, you can’t beat creeping phlox. It’s one of my favorite groundcovers for sunny slopes, rock gardens, or spilling over borders. Once established, it forms a thick mat of blooms that bees love.
14. Little Bluestem (Schizachyrium scoparium) – A Textured Ornamental Grass
If your sunny border needs a bit of texture and movement, Little Bluestem is a winner. Its blue-green summer foliage turns copper-red in fall—absolutely stunning. It thrives in tough spots and pairs well with perennial flowering shrubs.
15. Salvia (Salvia nemorosa) – A Versatile Landscaping Staple
Salvia is a must-have. The purple flower spikes bloom for weeks, and the bees and hummingbirds go wild for them. I grow it in the middle of beds where it adds upright structure and a reliable hit of color.
