foxglove ( Digitalis purpurea ), may extend up to 6 feet when in bloom, depending on the variety and growing conditions. It prefers moist, well-drained soil and full sun to medium shade. Its blossoms — in purple, pink, yellow and white — attract hummingbirds. Please note that all parts of the plant are poisonous to people, pets and livestock. Foxglove is considered invasive along the West Coast and in some parts of New England.
