Stems that grow to a height of 2 to 5 feet, with bell-shaped purple flowers, are the trademarks of foxglove. Known scientifically as Digitalis purpurea, foxglove is a toxic plant, used as an ingredient in several medications that are prescribed to treat blood pressure and heart conditions. Foxglove makes a vivid display in front of fences and walls or as the backdrop to a flower bed. Do not plant it in an area where animals will graze on it or children will play with it.
Choose a site in your garden or yard that receives full sun or light shade and has moist soil. While the soil should be able to retain moisture and stay cool, it should not trap water and be waterlogged.
Work the soil to a depth of 6 inches, and add in 2 inches of an organic compost mix, available at lawn and garden centers. Mix the compost in evenly with the soil.
Rake the top of the soil and smooth out the planting bed. Water the soil to a depth of 1 inch.
Sow seeds on top of the garden soil. Seeds are small, so disperse them carefully.
Cover the seeds with 1/8-inch layer of soil. Foxglove seeds need light to germinate, so you don't cover them with a thicker layer of soil.
When seedlings are 3 inches tall, thin them to a spacing of 18 to 24 inches apart.
Water twice per week if you have not received rain, moistening the soil to a depth of 2 to 3 inches.
Apply a general flower fertilizer, available in lawn and garden centers, once per month during the growing season, which is from the time you see them emerge in the spring until they go dormant in the fall. Follow package directions for proper amounts to use.
