Noteworthy Characteristics

Salvia azurea, commonly called blue sage, is a clump-forming perennial that typically grows to 3-5’ tall (shorter if pruned). Whorls of 2-lipped, azure blue flowers bloom in spikes from mid-summer to fall atop stiff stems clad with linear to lanceolate to obovate, grayish-green leaves (to 3-4” long). Salvia azura var. azura is native from North Carolina and Tennessee south to Florida and Texas. Salvia azurea var. grandiflora grows further west to New Mexico and further north to Nebraska and Minnesota.

Var. grandiflora is similar in appearance but has larger flowers and is often considered to be a better garden plant than var. azurea. Botanical variety name means large-flowered.

The genus name Salvia comes from the Latin word salveo meaning "to save or heal", in reference to the purported medically curative properties attributed to some plants in the genus.

Specific epithet means sky-blue for the azure blue flowers.


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.
