About This Plant
Foxglove's low-growing foliage is topped by 2- to 5-foot-tall flower spikes, depending on the variety. Flower colors include pink, red, purple, white, and yellow. Foxgloves are biennials or short-lived perennials. However, although individual plants may be short-lived, foxglove readily self-sows and multiplies. Foxglove leaves contain digitalis, a potent heart medicine, and are considered poisonous.
