Answer: If you are growing Digitalis purpurea (foxglove or purple foxglove), then you are growing a biennial. In the first year of growth, the plant produces a low-growing rosette of leaves only. In the second year it flowers, produces seed and dies. The plantperpetuates itself by self-seeding every other year and can quickly become a weed if not rouged out. Remember, annuals produce seed every year and then die. Perennials have a number of different means (crown, rhizomes, bulb, tuber, corm, etc.) to survive from year to year.
