Foxglove flowers, with their elegant blooms and towering spires, are one of the most striking plants you can grow in your garden. Known for their bold colors and unique shape, foxgloves are guaranteed to catch the eye. Whether you’re a seasoned gardener or just starting out, these flowers can thrive in a variety of garden settings with the right care.
What Are Foxglove Flowers?
Foxgloves (Digitalis purpurea) are biennial or short-lived perennial plants that produce tall, bell-shaped flowers in shades of pink, purple, white, and yellow. They are particularly known for their vibrant colors and speckled interiors, which add to their charm. Foxgloves can grow from two to five feet tall, with a spread of one to two feet, depending on the variety. Their towering presence makes them perfect for creating vertical interest in gardens.

Where to Plant Foxglove
Foxglove flowers are versatile and can thrive in many garden settings. They’re ideal for planting in borders, shade gardens, or under trees where they can benefit from dappled sunlight. As gardening expert Carrie Spoonemore suggests, foxgloves also work well as part of a layered garden design, where their height can complement shorter plants.
- Garden Beds: Use foxgloves as border plants to create height and drama in the garden.
- Shade Gardens: They thrive in partial shade, making them perfect for areas where other plants may struggle.
- Under Trees: Foxgloves grow well in areas with filtered sunlight, such as under trees.
How and When to Plant Foxglove
The best time to plant foxgloves is either in early spring or fall, as they establish roots well during these seasons. Ensure you plant them in a location with well-drained, rich soil. Foxgloves prefer slightly acidic to neutral soil, with a pH level between 6.0 and 7.0.
- Spacing: Sow foxglove seeds about 12 to 15 inches apart to give them room to grow.
- Soil Preparation: Amend the soil with compost to ensure it’s rich and fertile.
- Watering: Water the plants thoroughly after planting to help them establish.
Essential Foxglove Care Tips
Caring for foxgloves is relatively straightforward, but there are a few key areas to focus on to ensure healthy growth and vibrant blooms.
Light
Foxgloves do well in partial shade to full sun. In hotter climates, it’s best to plant them where they can receive morning sunlight and afternoon shade to prevent heat stress and encourage optimal blooming.
Fertilizer
To promote healthy growth, foxgloves benefit from a balanced, all-purpose fertilizer. Apply it in early spring to support the development of robust flowers. Avoid over-fertilizing, as this can result in excessive foliage growth with fewer blooms.
Watering
Keep the soil consistently moist, but ensure it is well-drained. Foxgloves do not tolerate soggy soil, so good drainage is essential to prevent root rot. Water regularly, especially during dry spells, but always allow the soil to dry slightly between waterings.
Pruning
To encourage new growth and prevent unwanted self-seeding, remove spent flowers (a process known as “deadheading”). This will also keep the plant looking tidy and healthy throughout the growing season.
Common Foxglove Pests and Problems
Foxgloves can be vulnerable to pests like aphids, spider mites, slugs, snails, and caterpillars. These pests can weaken the plant, leading to stunted growth, leaf discoloration, and even plant decline if not controlled.
- Pest Control: Regularly check your plants for pests and take action early. Use insecticidal soap or neem oil to manage infestations.
- Beneficial Insects: Encourage ladybugs and lacewings in your garden, as these insects can help control pest populations naturally.
How to Get Foxglove to Bloom
For healthy, abundant blooms, it’s crucial to provide the right growing conditions. Follow these steps to encourage your foxgloves to flower:
- Sunlight: Ensure they get partial to full sun, with some shade in hotter climates.
- Soil Moisture: Keep the soil moist, but well-drained, to avoid root rot.
- Fertilization: Use a balanced fertilizer, but avoid overfeeding.
- Deadheading: Remove spent flowers to encourage fresh growth and new blooms.
How to Propagate Foxglove
Foxgloves can be propagated by division in the spring or fall. If you have a mature plant that’s several years old, you can divide it into smaller sections. Here’s how:
- Dig up the plant carefully, ensuring not to damage the roots.
- Divide the root clump into sections, each with its own shoots and roots.
- Replant the divisions immediately in the garden, ensuring each section is well-watered to help it establish.
Foxglove flowers are a beautiful and versatile addition to any garden. With their stunning blooms and towering presence, they can brighten up borders, shade gardens, and even the spaces under trees. By providing the right light, soil, and care, you can ensure your foxgloves thrive and bloom beautifully each season. With proper attention, these plants will not only captivate with their unique beauty but will also continue to grow and flourish for years to come.
