Digitalis (pronounced /ˌdɪdʒɨˈteɪlɨs/[2] or /ˌdɪdʒɨˈtælɨs/[3]) is a genus of about 20 species of herbaceous perennials, shrubs, and biennials that are commonly called foxgloves. This genus was traditionally placed in the figwort family Scrophulariaceae, but upon recent reviews of phylogenetic research, it has now been placed in the much enlarged family Plantaginaceae.[1] This genus is native to western and south western Europe,[4] western and central Asia, and northwestern Africa. The scientific name means "finger-like" and refers to the ease with which a flower of Digitalis purpurea can be fitted over a human fingertip. The flowers are produced on a tall spike, are tubular, and vary in colour with species, from purple to pink, white, and yellow. The best-known species is the "Common Foxglove", Digitalis purpurea. This is a biennial plant which is often grown as an ornamental plant due to its vivid flowers. These range in color from various purple tints through various shades of light gray, and to purely white. The flowers can also possess various marks and spottings.

The first year of growth of the Common Foxglove produces only the stem with its long, basal leaves. During the second year of the plant's life, a long leafy stem from 50 to 200 centimeters tall grows atop the roots of healthy plants.
