Digitalis grandiflora (Big-flowered foxglove, Large yellow foxglove) is a species of flowering plant in the genus Digitalis, family Plantaginaceae (formerly Scrophulariaceae). It is native to southern Europe and Asia. In mountains it grows on warm, bushy slopes or areas left after logging.
It is an herbaceous biennial or perennial plant with glossy green, veined leaves, whose flowering stem can reach a height of 70–120 cm. The pale yellow flowers are spaced out on the stem, 3 to 4 cm long and show a netted brown marking in their interior.
As the plant contains cardenolides all parts are toxic. Its leaves contain 0.2% glycosides of the digitoxin-type and about 0,1% of the digoxin-type. Even so the plant is not used in the production of cardiac glycosides.
