While it’s easy to find red, orange, and pink flowers, blue blooms are a bit of a hidden treasure…when you spot them you know you’ve found something worth keeping. Fortunately, there are some great summer flowers that appear in shades of blue. Whether you’re looking for indigo, blue-violet, or baby blue, you can find a flower that matches the hue you love.

Blue is a color associated with tranquility, spirituality, and intelligence. Not only are blue flowers gorgeous, but they can also help evoke a sense of calm and peace…the perfect remedy to a long day or accompaniment to a serene relaxation spot. They also pair well with other colors, and mixing in bits of blue with warm-colored flowers and greenery adds some more excitement.

If you’re hoping to get your hands on some blue blooms, check out this list of 20 of our favorite blue flowers.

1. Balloon Flower (Platycodon grandiflorus)

This flowering perennial produces large, star-shaped flowers. Its name comes from the fact that its buds swell up big like a balloon before blooming. While the blue flowers are stunning, you should also keep an eye out for pink and white blooms.

2. Bellflower (Campanula spp.)

As you might have guessed, these plants produce bell-shaped blooms. Some varieties make great groundcovers and others are perfect for cut flowers. With so many options to choose from, you can find a type of bellflower that works perfectly in your garden.

3. Bluestar (Amsonia tabernaemontana)

Native to the Eastern United States, bluestar adds beauty to the garden and helps out bees and butterflies. In the spring, it sends up tons of blue star-shaped blooms. While these flowers fade by early summer, the plant’s leaves turn bright yellow in the fall. As a bonus, deer avoid munching on these plants!

4. Blue False Indigo (Baptisia australis)

If you’re looking for a native blue flower to add to your garden, blue false indigo is a great choice. While it’s related to peas, this bushy plant produces clusters of brilliant blue flowers. Native Americans used the blooms to produce a dye that looked similar to that made from the leaves of a true indigo plant (Indigofera tinctoria). Fun fact: the true indigo plant doesn’t have blue flowers!

5. Borage (Borago officinalis)

If you want a blue flower you can enjoy in the garden and on your plate, borage is the answer! This herb produces hundreds of tiny flowers that may be blue or pink. They taste like cucumbers and make a great addition to a salad or drink!

6. Bunnera (Brunnera macrophylla)

While many plants thrive in the sun, brunnera is happiest in a shady spot. These plants produce small blue flowers that resemble forget-me-nots, leading to the name false forget-me-not.

7. Cornflower (Centaurea cyanus)

Also known as bachelor’s buttons, cornflowers are annual flowers that produce cute, delicate flowers. If you plant them in your garden and let the flowers go to seed, you’ll end up with a cornflower patch year after year. Bachelor buttons also make great cut flowers, and they’re some of the best flowers for drying!

8. Delphinium (Delphinium spp.)

Delphiniums produce tall spikes (we’re talking up to five feet tall) adorned with pink, purple, or blue flowers. Due to their impressive height, they make garden backgrounds or borders along fences. They also have a decent vase life, so they’re perfect for adding some drama to flower arrangements.

9. Forget-Me-Knots (Myosotis spp.)

These little blue flowers with bright yellow centers adorn cottage gardens and hillsides alike. Since they easily reseed, one plant can easily turn into hundreds! While this plant is adorable, it carries a deeper meaning. People around the world use it as a symbol to remember those who have suffered and died.

10. Grape Hyacinth

While you may think this plant gets its name from purple flowers, it’s actually from the sweet grape scent it produces. The plants grow from bulbs and send up flower spikes each spring. The bundles of tiny blue flowers add a touch of charm and cuteness to any garden or vase.

11. Himalyan Blue Poppy (Meconopsis betonicfolia)

While you might think of bright red or orange blooms when you think of poppies, this species is here to show you that blue poppies exist! These flowers are native to the Himalaya mountains where they fill hillsides with a light blue color. They can be a bit difficult to grow, but figuring it out and you’ll be rewarded with delicate blue flowers.

12. Hydrangea (Hyrdrangea spp.)

There aren’t any flowers that can replace hydrangeas. These shrubs light up gardens with their large, billowy blooms. While legend says that making the soil acidic will change any hydrangea’s blooms to blue, this isn’t true! Only certain varieties of hydrangeas will turn blue with a low soil pH.

13. Lily of the Nile (Agapanthus spp.)

Also known as an African lily, this flower isn’t a true lily. The plants produce tall flower stalks that are covered with many flowers that resemble small lilies.

14. Lobelia (Lobelia spp.)

While lobelia flowers come in a variety of colors, the dark violet-blue is the most common color. These plants grow in full sun and produce blooms from early summer until the first frost. Their low-growing form makes them an excellent groundcover for your garden.

15. Love-in-a-Mist (Nigella damascena)

If the name alone doesn’t make you fall in love with this plant, its flowers will. The delicate star-shaped blooms are surrounded in a ‘mist’ of lacy leaves. They are great flowers for fresh bouquets or for drying.

16. Morning Glory (Convolvulaceae family)

Morning glories are vining plants that produce big, round blooms. Plus, they have super cute heart-shaped leaves. Most species of morning glory bloom during the day and close their flowers once night arrives, leading to the name. If you add these flowers to your garden, be aware that they can quickly take over. So watch them carefully!

17. Periwinkle (Vinca spp.)

You guessed it…these plants produce periwinkle-colored flowers! While there are lots of different periwinkle species, they are all low-growing plants that produce purple-blue flowers. While they’re commonly planted in gardens, you should be aware that they can quickly spread and cover your whole lawn!

18. Pincushion Flower (Scabiosa spp.)

All it takes is one look at these flowers to see where their name comes from. Their blooms resemble little pincushions dotted with a seamstress’s pins. They’re easy to grow at home, and they make excellent cut flowers for when you need a bit of intrigue for your flower arrangements.

19. Sea Holly (Eryngium bourgatii)

Also known as Oxford Blue, this blue flower looks like it’s from a different world. The rounded blue flower heads are surrounded by spiny blue bracts that slightly resemble blue holly leaves. Not only is this flower stunning, but it also makes

20. Siberian Squill (Scilla sibirica)
