Foxglove (Digitalis purpurea) is a tall, biennial flowering plant in the plantain family. It is native to Europe, but has been naturalized in many parts of the world. The plant has a rosette of basal leaves and can reach up to 1.5 meters in height when in bloom. The flowers are tubular, in shades of purple, pink, yellow, and white, and bloom in the late spring and early summer. Foxglove is a popular garden flower and is also grown commercially for its medicinal properties. The leaves and flowers contain cardiac glycosides, which are used to make digitalis, a heart medication.

Planning Your Garden With Foxgloves

As you plan your garden, it's important to think about the spacing, size, light, and nutrient requirements of all of your plant and how they'll grow together.

Some plants require more water than others, while other plants require dry soil. At the same time, some plants prefer full sun, and other plants need the shade to survive.

By studying what each plant requires and planning ahead where all of your plants will grow best, you can optimize your garden space.

Life Cycle Foxgloves are usually biennial, meaning they flower in their second year and then die.
