Pitcher's sage (Salvia azurea var. grandilflora) is a drought-hardy, humidity-proof native of the lower Midwest known for the pairs of blue flowers that open consecutively from late summer through fall. Native to thin nutrient-poor soils overlaying limestone, this plant can grow too tall and flop over if cultivated in richer soils. Cutting the total height of the plant back to half in midsummer has been used by some gardeners to reduce the incidence of this problem. Once established in the garden, Pitcher's sage is very drought-tolerant. The inch-long tubular flowers attract bees, butterflies, and hummingbirds.

The common name honors Dr. Zina Pitcher, a nineteenth-century Army surgeon and botanist.
