Blue Flowers Used for Filler in Arrangements

Delphinium

• Delphinium flowers are available in a wide range of blue shades, and their striking appearance and ability to last for days as cut flowers make them wonderful fillers in floral arrangements. The Iowa State University Cooperative Extension notes that delphiniums bloom as single or double flowers, and while blue is the most common color, some species feature white, pink, red, yellow and violet blossoms. The flowers bloom in large numbers on a terminal spike which makes them a great addition to tall floral arrangements.

Eryngium

• Eryngium flowers, more commonly known as "sea holly" and "Miss Wilmott's Ghost," are impressive flowers whose interesting shape adds an attractive architectural element to dried and fresh floral arrangements. The Colorado State University Extension notes that eryngium flowers come in a wide variety of sizes and colors, including shades of blue ranging from light, silvery blue to sea foam and purplish-blue to deep, inky hues. Some species noted for their blue flowers include Amethyst Sea Holly, Alpine Sea Holly and Mediterranean Sea Holly.

Grape Hyacinth

• Different species of grape hyacinth (Muscari armeniacum) bloom with stalks covered in small, bell-shaped flowers that range in color from vivid cobalt to bluish-green and bright blues to periwinkle. The slender flower stalks resemble tightly-packed clusters of grapes, and they add variation in height, texture and fragrance to floral arrangements. The University of Wisconsin Cooperative Extension notes that grape hyacinth's scientific name, Muscari, is derived from the Greek word for "musk" in tribute to the flower's sweet, grassy aroma.

Statice

• The University of Maryland Cooperative Extension notes that statice flowers (Limonium sinuatum), also known as sea lavender and marsh rosemary, are commonly used as floral arrangement fillers in both fresh and dried states. Twelve- to 24-inch flower stalks terminate in bunches of colorful blooms, with some producing flowers in shades of dark blue, sky blue and bluish-purple. When used in bouquets and arrangements, statice flowers represent remembrance.
