Foxglove (Digitalis purpurea) is a tall, biennial flowering plant in the plantain family. It is native to Europe, but has been naturalized in many parts of the world. The plant has a rosette of basal leaves and can reach up to 1.5 meters in height when in bloom. The flowers are tubular, in shades of purple, pink, yellow, and white, and bloom in the late spring and early summer. Foxglove is a popular garden flower and is also grown commercially for its medicinal properties. The leaves and flowers contain cardiac glycosides, which are used to make digitalis, a heart medication.
