Salvia azurea (Prairie sage or Blue sage) is a herbaceous perennial in the genus Salvia that is native to Central and Eastern North America.[1][2]
[edit] Description
Its thin, upright stems can grow to 6 feet (1.5m) tall, with narrow, pointed, smooth-edged to serrated, furry to smooth green leaves, connected to their stems by petioles to .4 inches long (1 cm).
The blue or white flowers, nearly 1/4 to 1/2 inch (7-12mm) long, appear summer to autumn near the ends of their branched or unbranched spikes; their calyxes are tubular or bell-shaped and furry. There are two varieties: Salvia azurea var. azurea (azure sage) and Salvia azurea var. grandiflora (pitcher sage).[1][2]
