Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Annual of varying habit, aromatic, without punctate-glandular leaves and flowers, stems square, sometimes tinged deep purple, herbage puberulent to somewhat glabrous. Leaves: Opposite, lanceolate to oblong-linear, margins with entire or serrulate, petioles 2-20 mm long. Flowers: Blue or bluish- white, borne in interrupted spikes in verticels of 2 opposite flowers, sometimes in leaf axils, the corolla strongly 2-lipped with the upper lip helmet-shaped, entire or 2-lobed, the lower lip spreading or drooping and 3-lobed. Calyx lobes bilabiate, persistent. 2 fertile stamens inserted in the tube of the corolla. Fruits: Four smooth nutlets. Ecology: Found on plains, mesas, rocky slopes, and open pine forest, from 4,000-7,000 ft (1219-2134 m); flowering July-October. Notes: The keys to this species are the annual habit, the lack of glandular-punctate vegetation, the blue or bluish-white flowers,the calyx lobes 2-lipped with with 12-13 ridges (nerves), the stamens inserted in the upper lip of the corolla, and the mostly linear-lanceolate leaves. Also look for this species in disturbed areas, roadsides, and pastures. The key to distinguishing between Salvia and Stachys is that Stachys has four stamens and a regular calyx, while Salvia has 2 stamens and the calyx is bilabiate. Ethnobotany: There is no specific use recorded for this species, but the genus was used as an infusion to treat measles, and eaten raw for kidney troubles. Synonyms: Salvia lancifolia Editor: LCrumbacher, 2011 Etymology: Salvia comes from the Latin salveo, "I am well," and an herb, Salvia, used for healing, while reflexa means bent sharply backwards.
From Flora of Indiana (1940) by Charles C. Deam
This western annual has been found established in a few counties. I found it to be well established in sandy soil in a barnyard about half a mile northeast of Leiter's Ford in Fulton County, and in a sandy truck garden along the Wabash River in Gibson County.
