This lovely herbaceous species is versatile and undemanding. It is the star of the late-summer garden with its spiky bright red flower buds and vivid blue flowers, displaying long-lasting mahogany red foliage in fall. Spreading slowly via underground runners, this long-lived plant makes a solid mat with erect, slender red stems and bright green leaves.

Regarded by some as the bluest blue fescue, this plant forms compact, cascading mounds of foot-tall, intensely blue, narrow leaves that are attractive in all seasons. Blooms are generally secondary to the foliage, but this cultivar blooms more heavily than most, with spikelets in summer. This cultivar is long-lived and very hardy. Grow in groups in a border or rock garden, or as a groundcover.

These compact tufts of 8-inch-long powder-blue leaves are well suited for edging and naturalizing in the rock garden. 

Deeply cut plum-purple leaves emerge in spring and stay true to color throughout the season. Lavender-blue flowers bloom beginning in late spring. 'Midnight Reiter' grows to only about 6 or 8 inches tall and twice as wide. More shade causes the foliage to be greener.

This mound of lavender-blue flowers and aromatic, grayish green leaves up to 2 feet tall and 3 feet wide is great as edging or in a border, herb, or rock garden. It is an easy to grow, prolific bloomer that seems to be deer resistant. It blooms the whole summer and tolerates some shade. It also looks great with roses or on walls.

This cultivar is a clump-forming perennial with toothed gray-green leaves and larger flowers than the hybrid. It flowers profusely and long, especially if sheared. The blue-purple flowers are small but abundant, and the foliage is aromatic.

This plant produces 3- to 4-inch-diameter, slightly scented flowers sporadically during summer, increasing in late summer through autumn. Intricate blossoms have an outer ruffle of petals and sepals; an inner disc of filaments composed of rings of blue, white and purple; and a central “antenna.” Deeply lobed dark green leaves cover stems that grasp supports with tendrils. Blue passion flower can reach 10 feet tall in one season. The ovoid, orange-yellow fruit is edible.
