Culture

Noteworthy Characteristics

Blue sage is a Missouri native perennial which occurs in dry soils on limestone glades, prairies and open ground. Typically grows 3-5' tall and features whorls of two-lipped, azure blue flowers in upright spikes which rise above the foliage. Flowers bloom in summer to fall. Narrow, lance-shaped, gray-green, basal foliage (to 4" long) with smaller stem leaves. Noticeably hairy stems. A mint family member that is attractive to bees and butterflies. This plant is synonymous with and sometimes sold as Salvia pitcheri or S. azura spp. pitcheri.

Problems

No serious insect or disease problems. Susceptible to leaf spot and rust and sometimes visited by white fly and scale. Usually needs some support since lax stems tend to lodge easily.

Garden Uses

Borders, cottage gardens, native plant gardens, prairie-like areas, wild or naturalized plantings.
