This drought-tolerant perennial bears abundant pure blue flower spikes in early summer and until fall if spent flowers are removed promptly. It forms an erect clump 20 inches tall by 18 inches wide, with wrinkled, softly hairy leaves.

This drought-tolerant perennial produces flower spikes in shades of violet, purple, or white to pink, with purple bracts. It blooms from early summer to autumn; reblooming is most reliable if spent flowers are promptly deadheaded. It has wrinkled leaves and forms an erect clump 3 feet tall by 2 feet wide. This species is most noted for its many S. sylvestris hybrids.

This woody-stemmed perennial produces sticky spikes of deep violet or, rarely, white to pink flowers. It blooms from early summer to autumn; reblooming is most reliable if spent flowers are deadheaded promptly. It has wrinkled leaves and forms an upright clump 3 feet tall by 1 foot wide. This salvia is most noted for its many hybirds with S. nemerosa.  

This hybrid of S. nemorosa and S. sylvestris is a drought-tolerant perennial that lends vivid purple-blue hues to the garden from summer to early fall on 1.5- to 3-foot-tall spikes. Deadheading prolongs bloom. The spikes rise from a clump of silvery green leaves that grows to about 2 feet tall and wide.
