Foxglove, a genus of about 25 species of Eurasian plants. The most important species is the common, or purple, foxglove, from which digitalis, a drug used to treat certain heart diseases, is obtained. The plant grows to a height of seven feet (2.1 m) and bears long, oval leaves with scalloped or toothed edges. The pink or purplish flowers are tube-shaped and point downward. They are borne in spikes on one side of a long stem.

Foxgloves belong to the genus Digitalis. The common foxglove is Digitalis purpurea.
