Digitalis (foxglove)

The plant is a beautiful herbaceous biannual or perennial with tufted basal leaves and single, erect, leafy stem which bears a spike or purplish flowers. Digitalis is from the Latin digitalis, meaning a finger, and refers to the finger –shaped corolla.  

Digitalis leaves have ovate or ovate-lanceolate lamina, 10-35 cm in length. Apex obtuse or rounded, base tapering into a winged petiole margin dentate or crenate; upper surface dark green, minutely, somewhat wrinkled, under surface greyish green; midrib greyish brown. The leaves are collected from July to September, from both the first and 2-nd year plants. Fresh and full-grown leaves are carefully and quickly dried for use as the source of the drug.
