My wife tells me that digitalis is made from Foxglove. I saw her fox glow blooming and asked what it was. Anyway here is a picture. I am off to read up on foxglove.
Wikapedia says,
"Digitalis is a genus of about 20 species of herbaceous perennials, shrubs, and biennials commonly called foxgloves. This genus was traditionally placed in the figwort family Scrophulariaceae, in 2001 it was moved to Veronicaceae after phylogenetic research, but more recent phylogenetic work has placed it in the much enlarged family Plantaginaceae. This genus is native to Europe, western Asia, and northwestern Africa. The flowers are produced on a tall spike, are tubular, and vary in colour with species, from purple to pink, white, and yellow. The scientific name means "finger". The best-known species is the common foxglove, Digitalis purpurea. This biennial plant is often grown as an ornamental plant due to its vivid flowers which range in colour from various purple tints through pink, and purely white. The flowers can also possess various marks and spottings. Other garden-worthy species include D. ferruginea, D. grandiflora, D. lutea and D. parviflora"
