If you’re looking for a stunning plant that thrives without full sun, knowing where to plant foxglove is your first step. These elegant spires are a classic choice for shady gardens, bringing height and color to darker corners.
Foxgloves, or Digitalis, are biennials or short-lived perennials. They are famous for their tall spikes of tubular flowers. They come in shades of pink, purple, white, and yellow. While they look delicate, they are surprisingly tough when given the right conditions. Getting the location right is the key to a healthy, blooming plant.
Where to Plant Foxglove
This is the core of your success. Foxgloves are woodland edge plants in their native habitat. This gives us the perfect blueprint for placing them in our own gardens.
Light Requirements: The Sweet Spot
Foxgloves prefer partial shade to light full shade. This means they want bright, filtered light for most of the day. Morning sun with afternoon shade is often ideal. They can handle a few hours of direct sun, especially in cooler climates. In deep, dense shade, they will grow but may become leggy and produce fewer flowers.
- Best: Dappled sunlight under open trees.
- Great: East-facing borders with gentle morning sun.
- Okay: North-facing spots with bright, indirect light.
- Avoid: Hot, baking afternoon sun in southern exposures.
Soil Conditions They Love
The soil is just as important as light. Foxgloves need soil that holds moisture but doesn’t stay soggy. They thrive in rich, well-draining earth.
- Drainage is Critical: Roots can rot in waterlogged soil. If your soil is heavy clay, add plenty of compost to improve its structure.
- Fertility: They appreciate soil rich in organic matter. Mix in well-rotted leaf mold or garden compost before planting.
- Acidity: They are adaptable but prefer slightly acidic to neutral soil (pH 6.0 to 7.0).
Ideal Garden Locations
Think about places in your yard that match these light and soil needs. Here are some perfect spots:
- At the back of a shaded flower border for vertical interest.
- Underneath deciduous trees like oaks or birches, where light filters through.
- Along a north-facing fence or wall that gets bright light but no harsh sun.
- In woodland garden settings, paired with ferns and hostas.
- In cottage garden schemes, where they can self-seed among other plants.
Companion Planting Ideas
Foxgloves look beautiful with other shade-tolerant plants. They create a layered, natural effect.
For Foliage Contrast:
- Hostas (with their broad leaves)
- Ferns (for fine, textured foliage)
- Heucheras (for colorful leaves)
For Flower Combinations:
- Astilbes (feathery plumes)
- Lungwort (Pulmonaria)
- Bleeding hearts (Dicentra)
- Hardy geraniums
How to Plant Foxgloves: A Step-by-Step Guide
Once you’ve chosen the perfect spot, follow these steps for planting.
- Timing: Plant in spring or early autumn. This gives the roots time to establish before extreme heat or cold.
- Prepare the Soil: Dig a hole twice as wide as the plant’s root ball. Mix the excavated soil with compost or leaf mold.
- Spacing: Place plants about 18 to 24 inches apart. This allows for good air circulation, which prevents disease.
- Planting Depth: Set the plant in the hole so the top of the root ball is level with the soil surface. Backfill with your soil mix and firm gently.
- Watering In: Water thoroughly after planting to settle the soil around the roots.
- Mulch: Apply a 2-inch layer of organic mulch (like shredded bark) around the base. This helps retain moisture and suppress weeds. Keep the mulch away from the stem itself.
Caring for Your Foxgloves
Proper care is simple but makes a big difference.
Watering
Keep the soil consistently moist, especially during dry spells in their first year and when they are flowering. Avoid overhead watering to keep the leaves dry and prevent fungal issues. Water at the base of the plant instead.
Feeding
Foxgloves aren’t heavy feeders. An application of a balanced, slow-release fertilizer in early spring is usually sufficient. Too much fertilizer can lead to lots of leaves and fewer flowers.
Staking
Tall varieties in very shady spots might need support. Insert a slim stake early in the season and tie the stem loosely as it grows.
Deadheading and Self-Seeding
After the flowers fade, you can cut the spike back to the base. This may encourage a second, smaller flush of blooms in some types. If you want plants to self-seed for next year, leave a few flower spikes on the plant at the end of the season to develop and scatter seed.
A Very Important Safety Note
All parts of the foxglove plant are highly toxic if ingested. This is crucial to remember.
- Wear gloves when handling plants, especially if you have sensitive skin.
- Plant them away from areas where children or pets play.
- Wash your hands after gardening around them.
- Despite their toxicity, they are safe to touch and are excellent pollinator plants for bees.
Troubleshooting Common Problems
Even with the best care, you might encounter an issue. Here’s how to handle it.
- Leggy Growth / Few Flowers: Usually means too much shade. Try moving them to a brighter spot (with indirect light) next season.
- Yellowing Leaves: Can be a sign of overwatering or poor drainage. Check that the soil isn’t waterlogged.
- Powdery Mildew: A white fungus on leaves. Improve air circulation, avoid wetting foliage, and remove affected leaves.
- Slugs and Snails: They love young foxglove leaves. Use organic deterrents like beer traps or crushed eggshells around plants.
FAQ About Planting Foxgloves
Can foxgloves grow in full shade?
They can survive in full shade but will often become very tall and leggy as they stretch for light. Flowering will be significantly reduced. Dappled or partial shade is much better.
Do foxgloves come back every year?
Common foxgloves (Digitalis purpurea) are typically biennial. They grow leaves the first year, flower the second, and then die. However, they often self-seed generously, creating a lasting colony. Some varieties, like Digitalis grandiflora, are true perennials.
Are foxgloves invasive?
They are not typically considered invasive, as they are easy to control. They self-seed readily, so you might find new seedlings each spring. You can simply pull them up if they appear in unwanted places.
When is the best time to sow foxglove seeds?
Sow seeds directly in the garden in late spring or early summer. You can also start them indoors in early spring. They need light to germinate, so just press the seeds gently into the soil surface; don’t cover them.
What animals leave foxgloves alone?
Because they are toxic, deer and rabbits generally avoid eating foxgloves. This makes them an excellent choice for gardens plagued by these animals.
Choosing the right location makes all the difference with foxgloves. By giving them the partial shade and rich, moist soil they prefer, you’ll be rewarded with magnificent flower spires that bring magic to the shadiest parts of your garden. Remember to consider safety with children and pets, and enjoy the buzz of bees these wonderful plants attract. With a little planning, you can have a stunning display year after year.
