The leaves of the Common Foxglove are the source of the medicinal drug digitalis. All the parts of the foxglove are highly poisonous. They add height to the back of flower beds, but they will not last past spring.

Culture:
They need a soil rich in organic matter to be at their best. Sow them in pots in late summer (early fall, or inside in Phoenix). The seeds should not be covered with soil, but just pressed in. Transplant in late fall. Set the young foxglove plants 1 foot apart (30 cm).
