Digitalis; named,by Fuchs, from digitabulum, a thimble in allusion to the form of the flowers.
The species are, for the most part, showy border flowers, ot easy culture.
Digitalis purpurea, with purple flowers; also a variety, D. alba, with white flowers; ornamental plants of great beauty, producing dense spikes of flowers on stems, three, four, or five feet high, in June and July, and straggling spikes most of the season. It is a biennial, propagated by sowing the seed, which flower the second year. The plant sometimes flowers the third year. It may be perpetuated by dividing the roots every year, and is sometimes called an imperfect perennial.
The plant is a violent poison, but valuable in medicine. It is suitable for the border, and may be introduced into the shrubbery with fine effect, as its tall, spire-like spikes, crowned with its large thimble or bell-shaped purple or white flower, will finely contrast with the green foliage of the shrubs.
