Blue flowers have a magical way of standing out in the garden. Whether they’re paired with vibrant reds or nestled among soft pastels, blue blooms bring depth, calm, and a touch of the unexpected. The best part? You don’t have to be a seasoned gardener to enjoy them. We’ve rounded up 10 easy-care blue flowering perennials that deliver jaw-dropping color without demanding much in return.
If you’re craving a garden that pops with personality—but don’t want to fuss over high-maintenance plants—these blue beauties are exactly what you need.
1. Salvia (Salvia nemorosa)
Zones: 4–9
Bloom Time: Late spring to early fall
Sun: Full sun
Salvia is a pollinator favorite that thrives with minimal effort. Its bold spikes of blue to violet-blue flowers keep blooming all summer if you deadhead spent blooms. Drought-tolerant and deer-resistant, it’s a staple in low-maintenance flower beds.
Tip: Cut it back after the first bloom to encourage a second flush of flowers.
2. Blue False Indigo (Baptisia australis)
Zones: 3–9
Bloom Time: Late spring
Sun: Full sun to part shade
This native perennial is tough as nails and brings dramatic height and color to the garden. Once established, it’s incredibly drought-tolerant and forms a bushy clump with elegant, lupine-like flowers in rich blue hues.
Bonus: The seed pods are ornamental and last well into fall.
3. Geranium ‘Rozanne’ (Cranesbill)
Zones: 4–8
Bloom Time: Late spring to frost
Sun: Full sun to part shade
‘Rozanne’ is a superstar perennial that churns out sky-blue blooms all season long. It sprawls beautifully and makes a fantastic ground cover. No deadheading necessary—this one just keeps going!
Perfect for: Containers, borders, or cascading over rock walls.
4. Virginia Bluebells (Mertensia virginica)
Zones: 3–8
Bloom Time: Early to mid-spring
Sun: Part shade to full shade
If you’ve got a shady spot that could use some spring charm, Virginia bluebells are your go-to. Their bell-shaped blossoms start out pink and shift to a dreamy blue. After blooming, they go dormant—so plant them near summer performers.
Great for: Woodland gardens and shaded borders.
5. Catmint (Nepeta)
Zones: 3–8
Bloom Time: Late spring to early fall
Sun: Full sun
Looking for a blue flower that practically thrives on neglect? Catmint’s lavender-blue blooms and fragrant silvery foliage tick all the boxes. It’s a magnet for bees and butterflies—and rabbits tend to stay away.
Low-maintenance hack: Cut it back mid-summer for a tidy second bloom.
6. Perennial Bachelor’s Button (Centaurea montana)
Zones: 3–8
Bloom Time: Late spring to early summer
Sun: Full sun
Bachelor’s Button flaunts fringed, electric blue flowers that add a burst of bold color to any bed. It’s not picky about soil, and it spreads gently over time without becoming a nuisance.
Try this: Pair with yellow coreopsis for a classic color contrast.
7. Lungwort (Pulmonaria)
Zones: 3–9
Bloom Time: Early spring
Sun: Part to full shade
Lungwort isn’t just about its shimmering blue flowers—it also has speckled, silvery foliage that looks good even after the blooms fade. It’s perfect for shady, moist spots that need brightening.
Bonus: Flowers may appear pink and blue on the same plant!
8. Balloon Flower (Platycodon grandiflorus)
Zones: 3–8
Bloom Time: Mid to late summer
Sun: Full sun to part shade
The name says it all. Before they bloom, these flowers puff up like tiny balloons—then burst open into starry blue blossoms. Once established, they’re nearly foolproof and bloom for weeks on end.
Heads-up: They’re late to emerge in spring, so mark the spot!
9. Himalayan Blue Poppy (Meconopsis)
Zones: 5–7
Bloom Time: Late spring to early summer
Sun: Part shade
The elusive Himalayan blue poppy is legendary for its otherworldly true-blue petals. While a bit fussier than others on this list, there are newer varieties that are much easier to grow in cooler climates with moist, well-drained soil.
Worth it if: You’ve got rich soil, cooler temps, and partial shade.
10. Campanula (Bellflower)
Zones: 3–8
Bloom Time: Late spring to mid-summer
Sun: Full sun to part shade
Campanulas come in a variety of sizes and shapes, but all share those classic bell-like blue flowers. They spread nicely but won’t take over, and they’ll charm you (and the bees) every year.
Tip: Choose taller varieties for borders or short ones for edging.
