Baptisia australis Baptisia australis
(blue false indigo, Plains false indigo)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

False blue indigo's spikes of clear blue flowers in late spring can nearly carry a border by themselves. They also make great cut flowers. Large, inflated nearly black seed pods set in after flowering, giving this plant another interesting element. It is low maintenance and will look great in any natural or informal setting.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This perennial produces long spires of large, deep blue flowers from mid-summer to frost. It forms a tall bush 6 feet tall by 2 feet wide that is great for the back of the border. It is drought tolerant because of its unusual, moisture-conserving rhizomes.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This short-lived perennial from the Himalayas has scented, hairy leaves and forms a small shrub 2 feet tall by 2 feet wide. It bears 1.5-inch-long purplish-blue flowers with white lips (called bee lines) from early to late summer. The flowers are clasped by rusty colored calyxes that accent color of the blooms. Salvias are some of the showiest plants for containers, annual borders, and mixed borders. Butterflies and hummingbirds love them.

(Sage)
(5 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This drought-tolerant perennial is noted for its vivid indigo flowers along deep purple-black stems, which gives it a bicolor appearance. It blooms in early summer and then sporadically if spent flowers are deadheaded. It forms an upright clump, with the flower spikes rising to 2 feet in height; its wrinkled, softly hairy leaves form a mound 1 foot high. Plants spread 1 or 2 feet wide. These are some of the showiest plants for containers and mixed borders. Butterflies love them.

(Blue throatwort)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This species bears dome-shaped flower heads several inches across that are crowded with tiny, tubular amethyst or white flowers that look somewhat like the blooms of an allium. It has lance-shaped, toothed leaves in hues of cordovan purple or deep green brushed with plum highlights. It blooms over a long season. Though it is a perennial, blue throatwort performs wonderfully as an annual and blooms summer to fall. Plants grow to about 3 feet tall and wide.
