Botanical description and distribution
Salvia aethiopis It is a biennial or perennial plant that can reach between 25 and 80 centimeters in height. Its stems are erect, robust, and branched, and are usually densely covered at the base with protective hairs, giving it a characteristic woolly texture.
The leaves The leaves of Salvia aethiopis are simple, predominantly basal, large, and have an ovate leaf blade and a dense covering of hairs and spheroidal glands. Their edges are irregularly lobed, toothed, or crenate. The upper surface is usually green, while the underside is whitish-green, an aspect that helps easily recognize the species in its wild state. The upper leaves are smaller and have a progressively decreasing arrangement as they approach the inflorescence.
La inflorescence It stands out for being wide, subpyramidal, and highly branched, composed of whorls that group 6 to 10 flowers. The bracts are broadly obovate, green or whitish-green, sometimes with the margin tinged with red or violet-purple. The flowers, white or pinkish-white, have a bilabiate, campanulate calyx with hairs and glands, as well as a straight tube without a ring of hairs inside.
El the habitat The native range of Salvia aethiopis ranges from southern and eastern Europe, including parts of Russia, Turkey, the Caucasus, and Iran, to large areas of Central Asia. It is frequently found along roadsides, slopes, fallow land, and areas frequented by livestock, and is characteristic of dry, slightly disturbed soils with moderate nitrogen levels. In the Iberian Peninsula, its presence is mainly concentrated in the northern half.
