Salvia leucantha, the Mexican bush sage, is a herbaceous perennial plant that is native to subtropical and tropical conifer forests in central and eastern Mexico.

It is not frost hardy, but is often grown in warmer latitudes for its prominent arching velvety blue or purple inflorescences.

The linear-lanceolate leaves are a soft mid-green, with whitish, hairy undersides.

[2][3] It is a low-maintenance plant that grows best in full sun and moist but well-drained soils.

[5] A recent analysis of the essential oil of S. leucantha found it to be rich in the sesquiterpene hydrocarbons; β-caryophyllene, α-guaiene, cis-muurola-3,5-diene, germacrene D, and bicyclogermacrene.
