Anise hyssop has subtle but eye-catching chartreuse foliage. Its powder-blue, long-lasting flowers contrast nicely with its leaves.

This early, compact bloomer grows to only about 6 or 7 inches tall. With its icy blue-purple flowers, it works well when planted tightly along the foreground of a bed. Its color blends easily with most other hues and textures. -Julia Jones, Designing with annueals, Fine Gardening issue #120

In summer, this colorful groundcover makes a 9-inch mound of saucer-shaped, deep blue flowers on long stalks.

Bachelor's buttons bear charming and prolific flowers in hues of blue, pink, lavender, white, and maroon. Those with a true blue color are especially welcome in the garden as that color is rare in nature. Each disc-shaped flower is about 1.5 inches across, with ragged petals radiating out from the center.

This tropical shrub or small tree may be grown in a mixed or shrub border; in colder climates, it does well in a temperate greenhouse. Flowers in shades of sky-blue, lilac, purple, or white blossom gracefully along arching branches in summer; they are followed by spherical, yellow fruit.
