Answer:
It is important to grow foxglove plants in partial shade in a well-drained, acidic soil. Well established foxglove plants will tolerate dry shade. Foxglove plants are susceptible to crown rot (rotting of the stem caused by fungal disease), so provide them with sufficient drainage. In order to avoid other common diseases in foxglove plants, give the plant a lot of space in order to help promote good circulation.
Side Note: Foxglove plants are one of the most poisonous plants that are commonly grown. Do not grow them if small children and/or pets spend a significant amount of time in the yard.
