20 Most Beautiful Blue Flowers

Blue Flowers

Blue is a color associated with tranquility, spirituality, and intelligence. It is thought to convey peace and promote a sense of calm. It also looks great with the rest of the colors in the rainbow, so it’s no wonder that blue is just about everyone’s favorite color.

So why are the perfect blue flowers so hard to find? Most types of blue flowers fall into a sort of bluish-purple category, and sunlight affects how the human eye perceives blue flowers.

To help you get a sense of what to look for—whether it’s destined for a bouquet or the garden—there are 20 types of blue flowers guaranteed to bring some low-key style to any room or garden.

  1. Bluestar
    Bluestar is one of the brightest blue flowers out there. The drought, rabbit, and deeper-resistant plant produces clusters of these clear, blue star-shaped blooms—delicate and vibrant at the same time. Lovely in the yard and breathtaking as an arrangement, Bluestar brings contrast to the table—pairing well with more subdued blooms in white or yellow.
  2. Blue Hydrangea
    We love hydrangeas. They tend to grow in bulk, populating large bushes with beautiful flowers in dark blue, sky blue–or white, pink, and purple. The kind of blue you get has more to do with the quality of the soil, rather than the breed. Acidic soil creates a deep blue color, while alkaline soil results in a lighter blue with a hint of pink.
  3. Bellflower
    Named for their distinctive bell-shape, bellflowers are beautiful little blooms that cluster together. While the dwarf types make good ground covers, the long stem varieties work well in any arrangement, adding little pops of blue to the mix.
  4. The Himalayan Blue Poppy
    The Himalayan Blue Poppy is something of a gardening legend. Shaped like the more familiar orange opium poppy, this varietal is striking in its vibrant cerulean hue. The plant is native to Southeastern Tibet, and as such, it can be difficult to grow outside of the region. That said, some US-based gardeners have had some luck raising these beautiful poppies, you’ll just need to keep things moist.
  5. Cornflower
    An adorable flower with a straw-like texture, cornflower, or bachelor’s button, is a European native that also does pretty well in North America. The plants grow up to three feet tall, with flowers accented by narrow, green-gray leaves. While these guys are often used in fresh arrangements, many enthusiasts choose to dry them so they can squeeze a bit more enjoyment out of their Bouq.
  6. Siberian Squill
    Siberian squill is a vibrant blue bloom, characterized by six, flat petals and their slight droop; these cold-resistant plants grow from a small bulb and can survive frost and a bit of snow. Additionally, their long stems make for a pleasant surprise element in any bouquet.
  7. Black and Blue Salvia
    A popular Salvia, native to South America, this plant is an attractive perennial that grows during mid-summer to early fall. The plant, which features large spikes of deep, cobalt blue flowers atop slender stems, attracts bees, birds, and butterflies. Use these as a vibrant accent plant in your next arrangement—we recommend pairing with bright colored blooms like zinnias or sunflowers.
  8. Blue Larkspur
    Blue Larkspur are distinguished by their iridescent petals that come in a range of blues from sky to royal. Giant larkspur can grow up to six or eight feet, while the more common varieties tend to hover around the two-foot range. While these spikes of blue blooms are a gorgeous addition to any arrangement, the seeds are quite poisonous, so keep that in mind if you have small children or pets hanging around.
  9. Blue Orchids
    If you’re wondering what types of flowers are blue, orchids likely aren’t going to be the first thing that comes to mind. Blue orchids look fake, but they’re a symbol of luxury, a rarity among a notoriously hard to grow breed. That said, many blue orchids are a product of cross-breeding, with a little help from some dye. Still, the rare blue vanda actually does occur in nature. This variety is a light bluish-purple, not that crazy bright blue you’ll see at the supermarket next to the teddy bears and potted mums.
  10. Blue Lobelia
    Lobelia is an annual herb with blue-violet flowers that grow in tall spike with delicate, bell-shaped blooms. Blue lobelia is a vibrant ground cover, the perfect complement to red geraniums or pink petunias.
  11. Blue Daisy
    The Blue Daisy isn’t really a daisy at all—rather, it’s a plant known as the Blue Marguerite—a close relative. Blue-fringed petals frame the yellow and green center, creating this bright, graphic element.
  12. Periwinkle
    More of a groundcover than a flower made for cut arrangements, periwinkle  is the quintessential blue-purple bloom best known by some for its namesake crayon. Periwinkle grows well in the shade and can easily cover any bald spots in your garden with its glossy leaves and star-shaped flowers.
  13. Forget-Me-Nots
    Forget-me-nots are one of those old-timey flowers, representing true love and remembrance. In the 15th century, people pinned the flowers on their clothing in the hopes they would not be forgotten by the one they loved. Folklore aside, these tiny blue flowers are characterized by a yellow center and are a cute way to brighten up your yard.
  14. Morning Glory
    Morning glory actually comes in a couple of different blues—darker indigo and a vibrant sky blue. These saucer-shaped blooms are popular in wedding arrangements and get their name from the fact that they bloom in the morning and die by night.
  15. False Indigo
    False indigo is a brilliant—yes, indigo-colored—plant that grows like a weed in the US. The reason for the name, is, false indigo is actually a member of the pea family, but Europeans used to buy the plant from American growers to produce a blue dye for a lower price than true indigo.
  16. Lungwort
    While lungwort doesn’t have the most appetizing name around town, the Spring-blooming perennial is often grown for its unique, spotted leaves–that herbalists of yesteryear thought looked like little human lungs (morbid, sure, but we don’t quite see it.) These beautiful perennials work wonders in shade gardens because of their long-lasting multicolor blooms, and their silver-pattern foliage.
  17. Columbine
    Columbines are springtime blooms that grow from a dark green foliage that shifts into maroon during the fall. Characterized by their oddly shaped flowers—two tiers of petals, with these “spurs” coming off the base—columbine may be delicate, but the blue and white variety is sure to pop in any garden bed.
  18. Scabiosa
    Scabiosa, also known as pincushion flowers are a summer bloom with an interesting texture created by an outer layer of tiny petals. The pincushion center is surrounded by frilly, lavender-blue petals that stand out against greens or vibrant reds and pinks.
  19. Anemone
    Anemone are these really unique cup-shaped flowers that get their name from the Greek word for “wind flower,” as the wind blows the petals open and sweeps away dead ones. The flower sits perched on an elongated stem, making them a surprising element that can be added to any vase.
  20. Grape Hyacinth
    Grape hyacinths come in a range of colors—purple as you might imagine, as well as white, yellow, and of course, blue. The easy-to-care-for plant grows from small bulbs, which can spread easily in well-drained soil. Oh, and the name “Grape Hyacinth” comes from the delightful grape bubblegum scent these guys produce.
