Salvia divinorum (also known as sage of the diviners,^[2] ska maría pastora,^[3] seer's sage,^[4] yerba de la pastora^[5] and just salvia) native habitat is in cloud forest in the isolated Sierra Mazateca of Oaxaca, Mexico, where it grows in shady and moist locations. The plant grows to over a meter high, has hollow square stems, large leaves, and occasional white flowers with violet calyxes. Botanists have not determined whether Salvia divinorum is a cultigen or a hybrid; native plants reproduce vegetatively, rarely producing viable seed.

Salvia divinorum has large green ovate (often also dentate) leaves,^[39] with a yellow undertone that reach 10 to 30 cm (4 to 12 in) long. The leaves have no hairs on either surface, and little or no petiole.^[7] The plant grows to well over 1 metre (3 ft) in height,^[1] on hollow square stems which tend to break or trail on the ground, with the plant rooting quite readily at the nodes and internodes.^[40]

The flowers, which bloom only rarely, grow in whorls on a 30-centimetre (12 in) inflorescence, with about six flowers to each whorl. The 3-centimetre (1.2 in) flowers are white, curved and covered with hairs, and held in a small violet calyx that is covered in hairs and glands. When it does bloom in its native habitat, it does so from September to May.^[40]

Early authors erred in describing the flowers as having blue corollas, based on Epling and Játiva's description. The first plant material they received was dried, so they based the flower color on an erroneous description by Hofmann and Wasson, who didn't realize that their "blue flowers, crowned with a white dome" were in fact violet calyces with unopened white corollas.

There are two commonly cultivated strains which are known to be distinct. One is the strain that was collected in 1962 by ecologist and psychologist Sterling Bunnell (the Bunnell strain), colloquially mis-attributed as the Wasson-Hofmann strain. The other was collected from Huautla de Jiménez in 1991 by anthropologist Bret Blosser (the Blosser or Palatable strain).^[48][49] There are other strains that are not as well documented, such as the Luna strain (possibly Bunnell) isolated from a Hawaiian patch of Salvia divinorum clones, featuring unusually serrated and rounded rather than ovate leaves.^[50]
