Foxglove thrives alongside ferns and hostas in partially shaded woodland gardens. Choosing the right foxglove companion plants is the secret to a lush, layered border that looks natural and intentional. You want neighbors that share similar moisture and light needs, but also bring different textures and bloom times to the table.
This guide will walk you through the best partners for your foxgloves, from shade-loving foliage plants to sun-tolerant perennials. You will also learn what to avoid, because not every plant plays nice with these towering beauties.
Why Companion Planting Matters For Foxgloves
Foxgloves are tall, dramatic spikes that bloom in early summer. They look a bit awkward standing alone in a bare bed. Their lower stems are often bare, leaving a gap of empty soil that invites weeds.
Companion plants fill that gap. They hide the leggy base of the foxglove and provide a lush skirt of foliage. More importantly, good neighbors can extend the interest of your garden well after the foxglove blooms have faded.
You also get practical benefits. Dense planting shades the soil, keeping roots cool and retaining moisture. This is vital for foxgloves, which dislike dry, baked earth. A living mulch of low-growing plants does this job perfectly.
Foxglove Companion Plants For Shade And Part Shade
Most foxgloves prefer dappled sunlight or morning sun with afternoon shade. This is the classic woodland edge environment. The best companions for this setting are plants that thrive in the same cool, humus-rich conditions.
Ferns: The Perfect Textural Backdrop
Ferns are the obvious first choice. Their delicate, feathery fronds contrast beautifully with the bold, upright spikes of the foxglove. They are also extremely easy to grow in shade.
- Lady Fern (Athyrium filix-femina) – Adds a soft, airy texture.
- Japanese Painted Fern (Athyrium niponicum) – Brings silver and burgundy tones to the mix.
- Ostrich Fern (Matteuccia struthiopteris) – Provides a tall, structural background.
Plant ferns behind or around the foxgloves. The fern fronds will catch the light and make the foxglove flowers pop. They also keep the soil shaded and moist, which is exactly what foxgloves need.
Hostas: Bold Foliage For Contrast
Hostas are the workhorses of the shade garden. Their large, ribbed leaves offer a solid, substantial contrast to the spiky foxglove flowers. You can choose from blue, green, or variegated varieties.
For a dramatic look, pair a deep purple foxglove with a large blue-leafed hosta. The color contrast is stunning. Smaller hostas work well at the front of the border, covering the foxglove’s bare stems.
One tip: slugs love hostas. If you have a slug problem, consider planting them further away from the foxglove base to avoid creating a slug highway.
Bleeding Heart (Dicentra)
Bleeding hearts bloom at the same time as foxgloves. Their arching stems of pink or white heart-shaped flowers create a lovely, romantic feel. They are also a great source of early-season nectar for bees.
These plants go dormant in the summer heat. This is fine, because the foxglove and other companions will fill in the space they leave behind. Plant them at the front of the border where their delicate flowers can be seen.
Columbine (Aquilegia)
Columbines are another early bloomer that pairs well with foxgloves. Their unique, spurred flowers come in many colors, from soft pastels to bright yellows. They are also excellent self-seeders, which means they will pop up in the gaps and create a natural, cottage-garden feel.
They prefer the same well-drained, humus-rich soil as foxgloves. They also appreciate a bit of afternoon shade, making them ideal companions in a mixed border.
Foxglove Companion Plants For Full Sun
Some foxglove species, like the Digitalis purpurea, can handle more sun if the soil is consistently moist. If you have a sunny spot, you need to choose plants that are equally tolerant of sun but still appreciate a cool root run.
Salvia (Perennial)
Salvias are fantastic partners for foxgloves. Their upright spikes of blue, purple, or red flowers echo the shape of the foxglove but in a completely different color palette. This creates a beautiful rhythm in the garden.
Salvias are also drought-tolerant once established, which helps balance the moisture needs of the foxglove. They attract hummingbirds and bees, turning your border into a pollinator hotspot.
Catmint (Nepeta)
Catmint is a low-growing, aromatic plant with soft gray-green foliage and spikes of lavender-blue flowers. It is a brilliant companion because it provides a frothy, soft texture at the base of the tall foxgloves.
It also blooms for a long time, often re-blooming after a shearing. This keeps the border looking fresh even after the foxgloves have set seed. The gray foliage also contrasts nicely with the green leaves of the foxglove.
Shasta Daisy (Leucanthemum)
For a classic, cheerful look, pair foxgloves with Shasta daisies. The white, sunny flowers provide a simple, clean contrast to the tall, tubular foxglove blooms. They are also tough and reliable, requiring very little maintenance.
This combination works well in a cottage garden or a more informal planting scheme. The daisies will help support the foxgloves by filling in the space around them, reducing wind damage and weeds.
Lupines
Lupines are another tall, spiky flower that can stand shoulder-to-shoulder with foxgloves. They come in a huge range of colors, including pink, purple, yellow, and white. Planting them together creates a stunning vertical display.
They prefer similar soil conditions—well-drained and slightly acidic. However, lupines are legumes, which means they fix nitrogen in the soil. This can actually benefit the foxgloves, giving them a gentle nutrient boost.
Foxglove Companion Plants For Ground Cover
Using low-growing plants as a living mulch is a smart strategy. It suppresses weeds and keeps the soil cool and moist. Here are some excellent ground-cover options.
Heuchera (Coral Bells)
Heuchera is a fantastic evergreen perennial with colorful, rounded leaves. You can find varieties in lime green, deep burgundy, caramel, and silver. They are perfect for the front of the border, creating a colorful carpet at the base of the foxgloves.
They also send up tiny, airy flower spikes in late spring that add a delicate touch. They prefer well-drained soil and partial shade, making them a versatile partner for many foxglove types.
Sweet Woodruff (Galium Odoratum)
This is a fast-spreading ground cover that thrives in shade. It has whorled, bright green leaves and produces tiny white flowers in spring. It is excellent for filling in large areas under trees or between taller plants.
It does spread aggressively, so you need to keep an eye on it. However, in a woodland garden, this is often a welcome trait. It creates a lush, green carpet that perfectly sets off the tall foxglove spikes.
Lamium (Dead Nettle)
Lamium is another excellent ground cover for shade. It has silver-marked leaves and produces clusters of pink, purple, or white flowers in spring. It is very tough and can handle dry shade better than most other ground covers.
It is also a great pollinator plant, attracting bees early in the season. Plant it in drifts around the base of your foxgloves for a polished, finished look.
What To Avoid Planting With Foxgloves
Not every plant is a good neighbor. Some will compete too aggressively for water or nutrients. Others will simply look wrong or create a maintenance nightmare.
- Aggressive Spreaders: Avoid plants like mint, bishop’s weed, or creeping Charlie. They will quickly choke out your foxgloves.
- Heavy Feeders: Plants like tomatoes or roses that need lots of fertilizer can compete with foxgloves for nutrients.
- Drought-Tolerant Plants: Plants like lavender or Russian sage prefer dry, lean soil. Foxgloves need consistent moisture, so these are a poor match.
- Very Tall, Dense Shrubs: Large shrubs can cast too much deep shade and steal all the moisture from the soil.
You should also avoid planting foxgloves too close together. They need good air circulation to prevent powdery mildew and rust. Give them at least 12 to 18 inches of space between plants.
How To Design A Foxglove Border
Creating a stunning border is about layering. You want to think in terms of height, texture, and bloom time. Here is a simple step-by-step guide.
- Start with the tallest plants: Place foxgloves in the middle or back of the border, depending on the view. They will be the main focal point.
- Add mid-height companions: Plant ferns, salvia, or lupines around them to create a second layer of interest.
- Finish with ground cover: Use hostas, heuchera, or lamium at the front to cover the soil and hide the bare stems.
- Mix in spring bulbs: Add daffodils or alliums for early color before the foxgloves take center stage.
- Consider bloom times: Choose plants that bloom before, during, and after the foxgloves to ensure continuous color.
This layering technique creates a dense, lush planting that looks like it belongs together. It also reduces the amount of weeding you need to do, which is always a win.
Foxglove Companion Plants For Pollinators
Foxgloves are famous for attracting bees and hummingbirds. You can boost this effect by adding other pollinator-friendly plants to the mix. This creates a vibrant, buzzing ecosystem in your garden.
Bee Balm (Monarda)
Bee balm is a magnet for bees, butterflies, and hummingbirds. Its unique, shaggy flowers come in red, pink, and purple. It prefers moist soil and full sun to partial shade, which aligns well with foxglove needs.
It is a bit taller, so place it behind or beside the foxgloves. The combination of spiky foxgloves and rounded bee balm flowers is visually striking.
Penstemon (Beardtongue)
Penstemons are native perennials with tubular flowers that hummingbirds love. They come in a range of colors, from deep red to soft pink. They are also quite drought-tolerant once established.
They prefer well-drained soil and full sun. This makes them a good choice for the sunnier edges of a foxglove bed. Their upright habit complements the foxglove spikes perfectly.
Agastache (Hyssop)
Agastache is another pollinator powerhouse. It has tall spikes of tubular flowers in shades of orange, pink, and blue. It is also aromatic, with a scent that is a mix of mint and licorice.
It is very drought-tolerant and loves the sun. Plant it in a sunny spot near your foxgloves to create a late-summer show when the foxgloves are done blooming.
Common Mistakes To Avoid
Even with the best companions, you can run into problems. Here are some common mistakes gardeners make with foxgloves.
- Planting in the wrong spot: Foxgloves need some shade, especially in hot climates. Too much sun will scorch the leaves and shorten the bloom time.
- Letting the soil dry out: Foxgloves are not drought-tolerant. They need consistent moisture, especially during their first year.
- Forgetting they are biennials: Most foxgloves are biennials, meaning they grow leaves the first year and bloom the second. Do not panic if they do not flower in year one.
- Not deadheading: If you want to prevent self-seeding, remove the spent flower spikes. If you want more foxgloves, leave a few to drop their seeds.
By avoiding these mistakes, you will have a much healthier and more beautiful display. Your companion plants will also thrive because they are growing in the right conditions.
Frequently Asked Questions
Can I plant foxgloves with roses?
Yes, you can. Roses and foxgloves are a classic cottage garden combination. The foxgloves fill in the gaps between the rose bushes and provide early-season interest. Just ensure the soil is rich and well-drained, and water regularly.
What grows well with foxgloves in a container?
In a pot, try combining foxgloves with trailing plants like lobelia or bacopa. You can also add a compact fern or a small heuchera for foliage contrast. Make sure the pot is large enough to accommodate the tall foxglove.
Do foxgloves need full sun?
Foxgloves prefer partial shade, especially in the afternoon. They can handle full sun in cooler climates, but they need consistent moisture. In hot climates, afternoon shade is essential to prevent the leaves from wilting.
Are foxgloves toxic to pets?
Yes, all parts of the foxglove plant are toxic to cats, dogs, and horses if ingested. They contain cardiac glycosides, which can cause serious heart problems. Be careful if you have curious pets that like to nibble on plants.
How do I stop foxgloves from self-seeding everywhere?
The best way is to deadhead the flowers before they set seed. Cut the flower spike back to the base once the blooms have faded. This also encourages the plant to put energy into its roots for the next year.
Final Thoughts On Foxglove Companions
Choosing the right foxglove companion plants is about creating a balanced, thriving ecosystem. You want plants that share similar cultural needs—moist, well-drained soil and partial shade. You also want a mix of textures and heights to create visual interest.
Start with ferns and hostas for a classic woodland look. Add salvia and catmint for a sunny border. Use heuchera and lamium as a living mulch to keep the soil cool. Avoid aggressive spreaders and drought-tolerant plants that will compete with your foxgloves.
