Salvia carduacea Benth.

Thistle Sage
Lamiaceae (Mint Family)


 

Thistle sage is an erect simple or few-branched annual with woolly herbage.  The spinose-toothed leaves are sinuate-pinnatifid, subsessile, generally oblong in outline and in a basal rosette.  The flowers appear on a scape to 20" tall in 1-4 interrupted whorls subtended by leafy, spinescent, densely white-wooly bracts.  The calyx is woolly with spine-tipped lobes and the corolla is lavender to blue, rarely white, with a laciniate upper lip and a lower lip with erose lateral lobes and a large fan-shaped fringed medial lobe.  The stamens are exserted and the anthers are reddish-orange. Thistle sage grows in dry sandy or gravelly places in chaparral and coastal sage scrub and also in the desert.  It blooms from March to June.
