  • Muscari Hyacinth Blue Flower Spikes

    Grape hyacinth. Good for naturalizing, these bulb plants will multiply to form a blue carpet in your early spring garden.

  • Columbine Flowers Come in Many Colors

    Columbine. Seemingly delicate petals and ferny foliage are the trademarks of this tough perennial. Depending on the variety, columbines bloom from midspring to early summer. Colors include yellow, pink, red, maroon, violet, white and bicolors. USDA Zones 3-8

  • Forget Me Nots

    Forget-Me-Not. The brilliant azure blue of forget-me-nots becomes a focal point in the spring shade garden. Pair with epimediums and foamflowers or let them provide a colorful contrast with hostas and ferns. USDA Zones 3-8, depending on variety

  • Siberian Iris Make Beautiful Landscaping Plants

    Siberian iris. A beautiful late-spring bloomer, Siberian iris is even easier to grow than bearded iris and tolerates a wider variety of soils. USDA Zone 3-9

  • Amsonia. Light-blue flowers appear in late spring or early summer on this bushy perennial. The willow-like leaves lend a fine texture to the garden and turn golden in fall. USDA Zones 3-9, depending on species.

  • Anemones Grow in Pprofuse Mounds of Blooms

    Anemone (aka Windflower). Depending on the variety (and there are many), these small, vividly hued flowers bloom in spring, summer or fall. They also come in pink, cream and purple. USDA Zones 2-8

  • Intricate Purple and White Passion Flowers

    Passion flower. Exotic flowers like these don't have to be limited to tropical gardens. A vigorous perennial vine that climbs via tendrils, the passion flower can be a conversation piece in the garden. Species vary from subtropical to hardy in USDA Zone 6.

  • Big-Blooming Morning Glory

    Morning glory. There's no reason to shun these old-fashioned annuals because they're invasive: the newer named varieties are well behaved and don't reseed with the same sort of abandon. 'Heavenly Blue' is a favorite.

  • Blue Hydrangea are Popular Garden Flowers

    Hydrangea. The hortensia hydrangeas produce masses of flowers so heavy that they often weigh down the branches. In acidic soils, the flowers are blue. In neutral soils, the flowers are pink.

  • Bellflower Blooms with Bright Blue Blossoms

  • Hardy Blue Harebell

    Campanula. This broad category of bellflowers ranges from the wild harebell to Canterbury bells, single blooms to large clusters of flowers. Colors include blue, lavender, white and pink. USDA Zones 3-9 (Pictured: Harebell)

  • Juncus Grass with Blue Foliage is Proven Winner

    Russian sage. This drought-resistant perennial produces its airy, lavender-blue spires from late summer to fall. Great to pair with sedums and ornamental grasses.

  • Globosa Blue Spruce Makes Excellent Landscape Tree

    Colorado blue spruce. If you don't have room for the towering (up to 60 feet tall) species form of this blue conifer, choose one of the dwarfs. 'Fat Albert' grows to 15 tall by 7 to 10 wide. 'Globosa' tops out at three feet square. Great for a sunny location. USDA Zones 3-7 (8 and 9 on the West Coast) (Pictured: 'Globosa')

  • Weeping Alaskan Cedar Makes Focal Point in Yard

    Nootka falsecypress. Also called weeping Alaskan cedar, this conifer typically comes in gray-blue or gray-green foliage. 'Glauca Pendula' has a bluish-gray cast; 'Coles Select' is bluer. USDA Zones 4 to 7 (Pictured: 'Glauca Pendula')

  • Siberian Bugloss

    Siberian bugloss (brunnera). Known for its often colorful, heart-shaped leaves, brunnera is a carefree plant that thrives in partial shade. The airy sprays of bright blue flowers appear in early to mid-spring. Give brunnera a well-drained soil that's consistently moist; this perennial won't tolerate occasional drought. USDA Hardiness Zones: 3 to 8

  • Beautiful Border Bulbs

    Delphinium.. These tough perennials bloom in early summer and sometimes again a couple of months later. Mature height can average anywhere from 2 to 8 feet tall, depending on variety; the flower stalks need staking on the taller types. Delphiniums are heavy feeders; plant in deep, rich soil. They also prefer cool summers and can't stand up to heat and humidity. USDA Zones 3 to 7
