Foxglove is a stately flower with tall, elegant spikes covered in bell-shaped blossoms beloved by hummingbirds and bumblebees. It’s also rabbit- and deer-resistant. Learn more about growing foxglove. 

About Foxgloves

Common foxglove (Digitalis purpurea) is a biennial or short-lived herbaceous perennial in most regions, although there are hybrids that grow in flower in year one. It is hardy in zones 4-9. 

In its first year, the plant simply forms a rosette and foliage; in the second year, the plant grows a 3 to 5-foot spike covered in 20 to 80 small downward-facing, tubular flowers in purple, pink, or white. 

Each flower tube has a small lip on which bumblebees can land to access the nectar at the base of the tube. Hummingbirds may also visit the flowers.

The flower blooms from late spring through midsummer and then dies. Therefore, for continuous blooms, plant it for two consecutive years. Or, look for varieties that flower in Year 1. 

Foxgloves are gorgeous in tall borders or background plantings and also look attractive against a background such as a building or a fence. They make excellent cut flowers.

Be aware that foxglove also self-seeds prolifically.  In some places, it’s considered an invasive plant. Deadhead after flowering to avoid an excess number of seedlings, or reconsider planting foxglove.

Is Foxglove Poisonous?

Yes. Foxglove is poisonous, although recorded poisonings from this plant are very rare. The plant contains digitalis and other cardiac glycosides. These chemicals affect the heart. To be poisoned from foxglove, you would need to eat the seeds, stems, or leaves, or suck the flowers.

Foxglove grows best in full sun, with light afternoon shade. The plant prefers moist, well-drained soil high in organic matter, with a slightly acidic to neutral pH. Prepare soil by mixing in a 3- to 4-inch layer of compost or aged manure.

When to Plant Foxglove

Sow seeds in late summer. Any seedlings should be planted into the garden bed in early fall so that they can establish the root system before cold weather arrives. 

Or, if planting containers, set out in late spring or fall.

How to Plant Foxglove

  • Foxglove is easy to grow from seed. If seeding, do not cover with soil; the seeds need light to germinate, so do not cover. Thin the seedlings to about 18 inches apart. 
  • When planting pots, space 1 to 2 feet apart; the foliage spread can be 1 to 3 feet. Dig the hole twice the diameter of the container. Set the top of the root ball level with the soil surface. Fill in around the root ball and firm the soil. Water thoroughly. 


  • Keep soil moist.
  • Add a thin layer of compost around the plant each spring.
  • Stake tall varieties to keep the flower stalks upright. 
  • Cut the center flower stalk back after flowering for a chance for additional flower stalks to develop later in the season. 
  • Leave the flower stalk on the plant if you want it to reseed, as well as to attract birds to the garden in the fall.
