Digitalis purpurea is an herbaceous plant native from Europe, Northeast of Africa and Central and occidental Asia. It is normally found in mountainous ambients like forest clearings, path edges, slopes, cliffs, rocks, recent wood cutting areas and, in general, silicon wet lands. In Europe, it often appears near from oaks and silver firs, although it is also found accompanying holm oaks and cork oaks in the South of Iberian Peninsula. It is widely spread in temperate climate zones, in the shades or half-shades. It flourishes in summer or autumn depending on the height. In countries of South America like Chile, it was introduced from Europe and it was widely spreaded in the South, between Maule and Magallanes. In Argentina it is located in the provinces of Jujuy, NEuquén, Río Negro and Tierra del Fuego. It is also common to find it in the North, specially in Colombia.
