Foxgloves are the kind of flowers that stop you in your tracks. With tall spires covered in bell-shaped blossoms, they bring a touch of old-world charm to any garden. These biennial or short-lived perennial plants are native to Europe but have found their way into cottage gardens, woodland edges, and wildflower meadows around the world. Their botanical name, Digitalis, hints at their medicinal history, but today they’re mostly grown for their dramatic beauty and pollinator-friendly nature.
Growing foxgloves isn’t difficult, but it does require a bit of patience and understanding of their lifecycle. Whether you’re starting from seed or planting nursery-grown specimens, this guide will walk you through everything you need to know to cultivate these stunning blooms.
Choosing the Right Foxglove Variety
Foxgloves come in a surprising range of colors, sizes, and growth habits. The classic Digitalis purpurea is known for its tall spikes of purple, pink, or white flowers, often speckled inside with darker spots. These are the quintessential cottage garden foxgloves, and they’re biennial-meaning they grow foliage the first year and bloom the second.
If you’re looking for longer-lasting plants, consider perennial varieties like Digitalis grandiflora, which produces creamy yellow flowers and tends to bloom more reliably year after year. Digitalis lutea offers smaller, pale yellow blooms and a more delicate appearance. For something truly eye-catching, hybrid varieties like ‘Dalmatian Peach’ or ‘Pam’s Choice’ offer unique colors and faster blooming cycles.
Choosing the right variety depends on your climate, garden style, and how much time you’re willing to wait for blooms. Biennials require a bit more patience but often reward you with taller, more dramatic flower spikes.
Understanding the Foxglove Lifecycle
One of the most important things to know about foxgloves is their biennial nature. In the first year, they produce a rosette of leaves and focus on root development. In the second year, they send up tall flower spikes and bloom, often spectacularly. After blooming, most biennial foxgloves die, although they may self-seed and start the cycle again.
Perennial varieties behave differently, blooming each year and living longer, though they may not be quite as tall or dramatic. Some hybrids blur the lines, blooming in their first year and persisting for several seasons.
Understanding this lifecycle helps you plan your garden. If you want continuous blooms, consider planting foxgloves two years in a row or mixing biennials with perennials. That way, while one group is growing foliage, the other is flowering.
Ideal Growing Conditions
Foxgloves thrive in cool to moderate climates and prefer partial shade, especially in hotter regions. They do well in dappled sunlight under trees or along north-facing borders. In cooler climates, they can tolerate more sun, but too much heat can cause stress and shorten their blooming period.
Soil is key. Foxgloves prefer rich, well-draining soil with a slightly acidic to neutral pH. Amend your garden bed with compost or leaf mold to improve texture and fertility. Avoid heavy clay or overly sandy soils unless you’re willing to amend them.
Good air circulation is important to prevent fungal diseases, especially in humid climates. Space plants about 12 to 18 inches apart to allow airflow between them.
Starting from Seed
Growing foxgloves from seed is a rewarding process, though it requires patience. Seeds can be sown directly in the garden or started indoors. If sowing outdoors, do so in late spring or early summer. For indoor starts, begin in late winter.
Foxglove seeds need light to germinate, so don’t cover them with soil. Simply press them into the surface of a moist seed-starting mix and keep them in a bright, warm location. Germination usually takes 10 to 20 days.
Once seedlings have a few true leaves, transplant them into individual pots or thin them in the garden. Keep them well-watered and protected from harsh sun until they’re established.
Remember, most foxgloves won’t bloom in their first year. You’ll see a rosette of leaves, and the real show will come the following season.
Planting Nursery-Grown Foxgloves
If you’re looking for faster results, nursery-grown foxgloves are a great option. These are often sold as young plants in spring or early summer, ready to be transplanted into your garden.
Choose healthy plants with strong stems and vibrant leaves. Avoid any with yellowing foliage or signs of disease. Dig a hole slightly larger than the root ball, place the plant in the hole, and backfill with soil. Water thoroughly to help settle the roots.
Mulch around the base to retain moisture and suppress weeds, but keep mulch away from the stem to prevent rot. Foxgloves don’t like soggy conditions, so avoid overwatering.
Watering and Feeding
Foxgloves appreciate consistent moisture, especially during their growing and blooming phases. Water deeply once or twice a week, depending on rainfall and soil conditions. Avoid overhead watering, which can promote fungal issues on the leaves and flowers.
Feeding isn’t strictly necessary, but a balanced fertilizer in early spring can boost growth and flowering. Use a slow-release granular fertilizer or a diluted liquid feed every few weeks during the growing season.
Organic options like compost tea or fish emulsion are also effective and gentle on the soil. Avoid high-nitrogen fertilizers, which can lead to excessive leaf growth at the expense of flowers.
Supporting Tall Spikes
One of the most striking features of foxgloves is their height. Some varieties can reach up to five or six feet tall, especially in ideal conditions. While this adds drama to your garden, it also means the flower spikes can be vulnerable to wind and rain.
Staking may be necessary, especially for taller varieties or those planted in exposed areas. Use bamboo stakes or decorative supports and tie the stems loosely with garden twine. Be gentle to avoid damaging the plant.
Planting foxgloves in groups can also help them support each other naturally. Dense planting creates a microclimate that protects against wind and encourages upright growth.
Deadheading and Maintenance
Deadheading foxgloves can encourage a second flush of blooms, especially in perennial varieties. Once the flowers fade, snip off the spike just above a leaf node. This redirects energy back into the plant and may result in new flower spikes.
For biennials, you may choose to let the flowers go to seed. This allows the plant to self-sow and continue the cycle. If you prefer a tidier garden, remove spent spikes before seeds develop.
Keep an eye out for yellowing leaves or signs of disease. Remove any damaged foliage promptly and dispose of it away from the garden to prevent spread.
Encouraging Self-Seeding
Foxgloves are generous self-seeders. If you allow the flower spikes to mature and drop seeds, you’ll likely see new seedlings popping up the following spring. These volunteers can be thinned, transplanted, or left to grow where they land.
To encourage self-seeding, avoid heavy mulching in late summer and fall. Seeds need contact with soil to germinate. You can also collect seeds manually by snipping off dried spikes and shaking them into a paper bag.
Store seeds in a cool, dry place and sow them the following season. Label them clearly, especially if you’re growing multiple varieties.
Common Problems and How to Solve Them
Foxgloves are generally trouble-free, but they can be affected by pests and diseases. Aphids, slugs, and snails are the most common culprits. Use organic slug pellets, beer traps, or copper tape to deter slugs. Aphids can be washed off with a strong spray of water or treated with neem oil.
Fungal diseases like powdery mildew or leaf spot may appear in humid conditions. Improve air circulation, avoid overhead watering, and remove affected leaves promptly.
Crown rot can occur in poorly drained soil. If your foxgloves suddenly wilt and collapse, check the base for signs of rot. Improve drainage and avoid planting in low-lying areas.
Safety Considerations
Foxgloves are beautiful but toxic. All parts of the plant contain compounds that can affect the heart if ingested. Keep them out of reach of children and pets, and wear gloves when handling large quantities or cutting back.
Despite their toxicity, foxgloves are not dangerous to grow. Just treat them with respect and educate others who may be curious about the plants in your garden.
Styling Foxgloves in Your Garden
Foxgloves add vertical interest and a touch of romance to any garden. They pair beautifully with roses, delphiniums, and peonies in cottage-style borders. In woodland gardens, they mingle well with ferns, hostas, and astilbes.
Use them as back-of-the-border plants or let them peek through shrubs and hedges. Their height makes them ideal for creating layered planting schemes, and their soft colors blend seamlessly with most palettes.
You can also grow foxgloves in containers, though they’ll need deep pots and regular watering. Choose dwarf or compact varieties for best results.
Final Thoughts
Growing foxgloves is a journey that rewards patience and care. From tiny seeds to towering spires, these plants offer a dramatic transformation that few others can match. Whether you’re cultivating a wildflower meadow or designing a formal garden, foxgloves bring elegance, structure, and a touch of magic.
With the right conditions and a little attention, your foxgloves will bloom year after year, attracting bees, hummingbirds, and admiring glances from every visitor. Let them grow, let them seed, and let them surprise you. That’s the beauty of gardening-and the charm of foxgloves.
