Foxglove
Digitalis purpurea
📖 About this plant
A striking biennial or short-lived perennial producing tall, dramatic spires of tubular flowers in shades of purple, pink, white, and yellow, often with speckled throats. Foxgloves are a cottage garden classic that naturalizes beautifully in woodland edges and partially shaded borders. They are the source of the life-saving heart drug digitalis, but must never be consumed raw or without medical supervision.
