Azure Blue Sage

(Salvia azurea var. grandiflora)

Salvia azurea var. grandiflora

Unlike many other striking blue-flowered sages, this one is hardy in the Chicago area. 

“It needs full sun and limited additional irrigation during the growing season,” says Boyce Tankersley, director of living plant documentation. “The flowers are visited by a wide array of pollinating insects and by hummingbirds as they begin their fall migration.”
