Salvia azurea, the azure blue sage,[1] azure sage, blue sage or prairie sage, is a herbaceous perennial in the genus Salvia that is native to Central and Eastern North America.[2][3]



Its thin, upright stems can grow to 6 feet (1.8 m) tall, with narrow, pointed, smooth-edged to serrated, furry to smooth green leaves, connected to their stems by petioles to 0.4 inches (1.0 cm) long. There are no basal leaves.[4]

The blue flowers (rarely white), nearly 14 to 12 inch (6.4 to 12.7 mm) long, appear summer to autumn near the ends of their branched or unbranched spikes; their calyxes are tubular or bell-shaped and furry. Two varieties are Salvia azurea var. azurea (azure sage) and Salvia azurea var. grandiflora (pitcher sage).[2][3] It is found on the wild on roadsides, glades, fields and pastures.[4]
