'Indigo Spires' sage is a vigorous hybrid prized for its 12- to 15-inch-long, twisting spikes of dark violet flowers. It is a non-stop bloomer from early summer through fall. Blooming can be further encouraged by pinching stem tips early in the growing season and deadheading the spikes once they fade. 'Indigo Spires' quickly grows to 4 feet high, and can be grown as an annual where not hardy.  

From late spring to fall, this easy-going perennial bears deep orange-red flowers on 3- to 4-foot-tall spikes that rise above a loose, 6-foot-wide mound of heart-shaped, sticky leaves. The native habitat for this brightly colored salvia is a very limited area at an altitude of 9,000 feet in the narrow range of the Mexican Sierra Madre Oriental Mountains.

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.

This low-growing perennial produces long-lasting light pink blossoms with dark pink centers. It is an heirloom cultivar of the native species. Verbenas are excellent for annual borders, containers—especially hanging baskets—and some for the mixed herbaceous border.
