Natural Blue Flowers: Unique, Extraordinary and Rare

Crystal Blue Salvia

Blue is the color of the sky and oceans; blue is seen all around us in nature when we look up and when we look to the sea. A place that blue is not so common in nature is in the garden. True blue flowers are rare, which makes blue flowers in the garden highly desired.

When thinking of summer flowers that are true blue a couple come to mind: delphiniums, veronica, salvia, and Siberian iris. When I think of spring flowers that bloom in shades of true blue plenty more come to mind.

Garden Design With Blue Flowers

Before choosing what blue flowers to add to the garden there are some design tips to consider. Cool colors such as lavender and true blue make garden spaces appear larger. Small space gardens will benefit from the addition of blue flowers to enhance the space.

You can create a monochromatic garden by planting various shades of blue flowers in the same area. Monochromatic gardens create an impact on the eye by the volume and consistency of one color growing in one area.

Variety is the spice of life and if you prefer your garden to have a variety of colors that is fun too! Colors that look good when planted with blue flowers are: blue with yellow, blue with red, blue with purple, blue with orange and blue with white. With blue blending well with so many colors the color blue almost acts in a similar way that green does in the garden. Meaning that both are considered colors but their ability to blend well with most other colors in the garden has them behaving like a neutral color. For spring blooms, combining blue blooms with red tulips, yellow daffodils, purple tulips, orange fritillaria or white allium is easily done.  Not sure what blue flowers to plant this fall?

Top 12 Spring Blooming Blue Blooms

Blue Grape Hyacinths

Blue Grape Hyacinths

Blue Grape Hyacinths are one of the most popular blue spring-blooming flowers. Grape hyacinths are also commonly referred to by their botanical name Muscari. These easy to grow bulbs bloom mid-season typically when the tulips and daffodils are blooming. Grape Hyacinths are low growing reaching heights of only about 4-6″. The close to the ground habit of muscari and their ability to multiply make them a top choice for natural settings. Blue Grape Hyacinths are used in lawn plantings for a dramatic blue display among blades of green grass. Wooded garden areas look enchanting with sweeps of blue muscari planted on the edges. The spiky clusters of blue flowers are small so it is best to plant muscari in large groups. Planting 14-18 muscari bulbs per square foot will provide the biggest color impact from near and far.

Camassia

Camassia

Also known as Wild Hyacinth the star-shaped blooms of Camassia are a true electric blue. Whispy in nature, the flowers bloom late in the spring season after the daffodils and tulips have put on their display. Camassia is native to North America and can be found in meadow areas. Maturing at 16-22″ Camassia works well mixed in with perennials or planted in front of peonies. The blue flowers complement blooms of light pink and true pink peony blooms.

Blue Jacket Hyacinths

Blue Jacket Hyacinth

Harmony is created in the early spring garden with these adorable dwarf Dutch Iris. Dwarf Dutch Irises are low to the ground early spring blooming flowers.

This tall Dutch Iris blooms later than the Harmony Dwarf Dutch Iris mentioned earlier. The blue blooms on this slender iris have yellow accents for added color and dimension. Dutch Irises grow from true bulbs as opposed to rhizomes (rhizomes are what bearded iris grow from). A key feature to the Blue Diamond Dutch Iris is the late spring bloom time.
