Description
It is a herbaceous perennial growing from a short rootstock with fibrous roots. D. grandiflora has glossy green, veined leaves, whose flowering stem can reach a height of 70–120 cm (28–47 in). The pale yellow bell-shaped flowers are spaced out on the stem, 3–4 cm (1–2 in) long and show a netted brown marking in their interior. In the wild, plants bloom in June and July.
In medicine
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.
