History and Folklore
The origin of the common name “foxglove” is unclear, but the original name may have been folksglove, referring to faerie folk.
The Latin name, digitalis comes from the word digitanus, meaning finger for the thimble-shaped flowers that look like you could fit your finger right inside.
Although foxglove is very dangerous if misused, it has a long history of medicinal use for heart and kidney problems, edema and aconite poisoning. Legend says that Van Gogh used it to treat his epilepsy.
An old saying about foxglove goes “It can raise the dead and it can kill the living”.
In the 1700s, William Withering learned of this folk remedy from “an old woman in Shropshire” and studied it. This led to Digitalis being a very important plant-derived medicine for heart disease that is still in use to this day.
In Roman mythology, Flora showed Hera or Juno how to impregnate herself with no need of a man by touching a foxglove to her belly and her breasts. Depending on the source, she either gave birth to Mars or Vulcan from this method.
Scandinavian legend says that the faeries taught foxes to ring foxglove bells to warn each other of approaching hunters.
Foxglove, or digitalis, has a long association with witches and witchcraft.
Foxglove will grow in most zones, but not along the gulf coast. It likes a bit of sun, but scorches easily and requires a bit of shade in the latter part of the day. If you live in the deep south, it will do best in the deep shade. Foxglove germinates well from seed.
Just throw it down, no need to even cover it or fertilize it. Plant foxglove in moist but well-drained soil that is slightly acidic, but remember, they are biennial so you won’t get any blooms until next year.
It will then self-seed and you will need to divide the clumps every few years to prevent overcrowding. Mulching will prevent reseeding.
Harvesting & Storage
Cut flowers when they first bloom and hang upside down to dry.
Be sure to wear gloves when working with foxglove.
