About Hyoscyamus aureus L.
Hyoscyamus aureus L. is a very sticky, long-haired perennial plant that often grows in a densely sprawling form. Its flowers are asymmetric, with petals positioned toward the upper side of the bloom. They are golden yellow with a purple throat, and the stamens and style extend far out beyond the petals. After flowering, the inflorescence grows much longer; when the structure withers, small new plantlets can form at its ends. Its leaves are roundish to egg-shaped with irregular edges, borne on long stalks that reach up to 3 cm in length, and the leaf base is variable. It can be distinguished from similar related species: Hyoscyamus albus has paler yellow flowers and non-protruding stamens; Hyoscyamus niger is an upright plant with lurid yellow flowers marked by purple veins and speckles. Early vegetative-stage Ecballium elaterium can resemble this species, but E. elaterium has coarse hairs and very prominent net-like veins on the underside of its leaves. This information is sourced from Flora Europaea and Flora of Turkey. In Turkey, Hyoscyamus aureus L. grows in rock crevices, old walls, and ruins, at elevations between 0 and 1200 meters.
