Lung Wart Planted with Coral Bells
Lung wart and coral bells create a magical shade garden duo with complementary foliage textures and bloom times. This guide covers everything from planting techniques and soil preparation to ongoing care and design inspiration for year-round garden beauty.
There’s something truly special about walking through a shade garden in early spring and discovering the first blooms of lung wart pushing through the soil. Those delicate pink and blue flowers, often appearing on the same plant, signal the true start of the gardening season. But here’s the thing – lung wart doesn’t have to shine alone. When you plant lung wart with coral bells, you create a partnership that delivers beauty from March through November.
I first discovered this combination quite by accident. A few years back, I tucked a few coral bells plants around some established lung wart in a shady corner near my front porch. I wasn’t thinking about design principles or bloom succession – I just had extra plants and empty space. The result surprised me. The broad, silver-spotted leaves of the lung wart made the ruffled purple foliage of the coral bells pop, and when the coral bells sent up their delicate flower spikes in June, the lung wart’s foliage was still looking fresh and handsome. It was one of those happy garden accidents that teaches you more than any book could.
Whether you’re a seasoned gardener looking to refine your shade plantings or someone just starting to explore the possibilities of low-light gardening, understanding how to grow lung wart planted with coral bells opens up a world of design possibilities. These two perennials share similar cultural needs but offer distinctly different textures, colors, and seasonal interest. Together, they create a tapestry that’s far more interesting than either plant alone. Let’s dig into everything you need to know to make this dynamic duo work in your garden.

Quick Answers to Common Questions
Can lung wart and coral bells grow in full shade?
Yes, both plants tolerate full shade but flower best with some morning light or dappled shade. Deep shade may reduce blooms and dull coral bells foliage colors.
How often should I divide these plants?
Lung wart benefits from division every 3-4 years to maintain vigor. Coral bells should be divided every 3-4 years to prevent woody centers and the “donut effect.”
Are lung wart and coral bells deer resistant?
Both plants are generally deer resistant due to their hairy or tough foliage, but no plant is completely deer-proof. Hungry deer may sample them.
Can I grow these in containers?
Absolutely. Both perform well in containers at least 14 inches wide and deep. Use quality potting mix, ensure good drainage, and water and fertilize more frequently than in-ground plants.
Why is my lung wart not flowering?
Common reasons include: too much shade, plant is too young (first-year plants bloom sparsely), overcrowding requiring division, or late spring frost damaging buds.

Understanding Your Plant Partners
Getting to Know Lung Wart
Lung wart, botanically known as Pulmonaria, belongs to the borage family and has been cultivated in gardens for centuries. The common name comes from the doctrine of signatures – medieval herbalists believed the spotted leaves resembled diseased lungs and therefore the plant must be good for treating lung ailments. While we don’t rely on it medicinally anymore, the name stuck.
These herbaceous perennials form low, spreading clumps typically reaching 8 to 12 inches tall and 18 to 24 inches wide. The real show starts in very early spring, often before the last frost, when flower buds emerge on short stems. The flowers are fascinating – they open pink and gradually turn blue as they age, so a single plant often displays both colors simultaneously. This color change happens because the pH of the flower tissue shifts as the bloom matures.
The foliage appears after flowering and remains attractive throughout the growing season. Most varieties feature lance-shaped leaves splashed or spotted with silver or white, though some newer cultivars offer nearly solid silver leaves. The leaves have a slightly rough, hairy texture that deer and rabbits tend to avoid – a definite plus in many gardens.
Meeting Coral Bells
Coral bells, or Heuchera, are North American natives that have undergone a remarkable transformation in recent decades. Once grown primarily for their airy flower spikes, modern breeding has produced an astonishing array of foliage colors – deep purple, caramel, chartreuse, peach, silver, and near-black. The leaves are typically lobed or ruffled, forming neat mounds 12 to 18 inches tall and wide.
In late spring to early summer, slender stems rise above the foliage bearing tiny bell-shaped flowers in shades of white, pink, or red. While the flowers are lovely and attract hummingbirds, most gardeners grow coral bells for their spectacular foliage that provides color all season long. Many varieties are semi-evergreen, holding their leaves well into winter in milder climates.
Why They Work Together
The magic of planting lung wart with coral bells lies in their complementary characteristics. Lung wart wakes up early, flowering when the garden is still mostly brown. Its broad, coarse-textured leaves then provide a backdrop for the finer, more colorful foliage of coral bells as they emerge. By the time lung wart’s spring show winds down, coral bells are hitting their stride.
Both plants prefer similar conditions – partial to full shade, rich soil, and consistent moisture. Neither is aggressive, so they’ll politely coexist for years without one overwhelming the other. Their root systems occupy slightly different soil depths, reducing competition. And perhaps most importantly, they look like they belong together – the silver-spotted leaves of lung wart echo the silver veining found in many coral bells varieties.
Site Selection and Soil Preparation
Finding the Perfect Spot
Success with lung wart planted with coral bells starts with choosing the right location. Both plants thrive in what gardeners call “bright shade” or “dappled shade” – areas that receive filtered sunlight through tree canopies or a few hours of morning sun followed by afternoon shade. They’ll tolerate deeper shade, but flowering may be reduced and coral bells foliage colors won’t be as vibrant.
Avoid hot afternoon sun, especially in southern climates. Both plants can scorch in intense light, with lung wart leaves developing brown, crispy edges and coral bells colors bleaching out. If your only option is a sunnier spot, look for varieties specifically bred for sun tolerance – some newer coral bells cultivars handle more light, and a few lung wart selections are more sun-tolerant than others.
Consider the view from your windows and seating areas. This combination shines in early spring when you’re eager for garden color, so plant it where you’ll see it daily. Near a kitchen window, along a shaded walkway, or at the edge of a woodland path are all perfect locations.
Soil Requirements
Both lung wart and coral bells prefer rich, humusy soil that drains well but retains moisture. Think of the forest floor – that’s the ideal model. If your soil is heavy clay, sandy, or nutrient-poor, you’ll want to amend it before planting.
Work in 2 to 3 inches of organic matter such as compost, well-rotted leaf mold, or aged manure into the top 8 to 10 inches of soil. This improves drainage in clay soils, increases water retention in sandy soils, and provides slow-release nutrients. A soil pH between 6.0 and 7.0 is ideal for both plants.
If you’re planting in an established bed, you can top-dress with compost annually rather than disturbing existing roots. A layer of shredded leaves in fall mimics natural forest processes and feeds the soil as it breaks down.
Drainage Considerations
While both plants like consistent moisture, neither tolerates standing water. Crown rot is the primary killer of coral bells, and lung wart can suffer in soggy conditions too. If your site has poor drainage, consider creating raised beds or mounding the soil slightly to improve drainage around the crowns.
Test drainage by digging a hole 12 inches deep and filling it with water. If it doesn’t drain within a few hours, you have a drainage issue that needs addressing before planting.
Planting Techniques for Success
Timing Your Planting
Spring and fall are both excellent times to plant lung wart with coral bells. Spring planting gives the plants a full growing season to establish before winter, but you’ll need to water diligently through summer heat. Fall planting allows roots to establish in cool, moist conditions with less watering needed, but plants should be in the ground at least 6 weeks before the ground freezes.
If you’re dividing existing plants, early spring just as new growth emerges is ideal for lung wart. Coral bells can be divided in spring or early fall. Divisions establish quickly and are an economical way to expand your planting.
Spacing and Arrangement
Space lung wart plants 18 to 24 inches apart and coral bells 12 to 18 inches apart. When combining them, consider their mature sizes and growth habits. Lung wart spreads slowly by rhizomes, while coral bells stay in tight clumps.
For a natural look, plant in odd-numbered groups – three or five of each variety. Intermix them rather than planting in blocks. A pattern like lung wart, coral bells, lung wart, coral bells creates a more organic feel than distinct sections. Stagger the rows rather than planting in straight lines.
Consider the viewing angle. Place lower-growing lung wart toward the front of borders where its early flowers can be appreciated up close. Coral bells, with their slightly taller foliage mounds, work well behind or intermingled.
Planting Step by Step
Water both plants thoroughly while still in their pots. This reduces transplant shock and makes removal easier. Dig holes twice as wide as the root balls but no deeper. You want the crown – where stems meet roots – to sit at or slightly above soil level.
Gently loosen any circling roots. Place the plant in the hole, backfill with amended soil, and firm gently to eliminate air pockets. Water deeply to settle the soil around roots. Apply a 2-inch layer of mulch such as shredded bark, leaf mold, or pine straw, keeping it away from the crowns.
Water new plantings every 2 to 3 days for the first few weeks, then gradually reduce frequency as plants establish. The goal is consistently moist but not soggy soil.
Seasonal Care Calendar
Spring Awakening
Early spring is lung wart’s moment. As soon as the ground thaws, you’ll see flower buds pushing up. Resist the urge to clean up too early – last year’s foliage protects the crowns from late freezes. Once new growth is clearly emerging, gently remove any tattered old leaves.
This is also the time to apply a light feeding. A balanced, slow-release organic fertilizer or a top-dressing of compost around the plants provides nutrients for the growing season. Avoid high-nitrogen fertilizers which promote lush foliage at the expense of flowers.
Watch for slugs and snails which love the tender new growth of both plants. Beer traps, diatomaceous earth, or pet-safe slug baits can protect your plants during this vulnerable period.
Summer Maintenance
After lung wart finishes flowering, you can deadhead the spent flower stems to tidy the plant. Some gardeners shear the entire plant back by about half after blooming to encourage fresh foliage growth. This isn’t strictly necessary but can improve appearance, especially in hot summers when leaves may look tired.
Coral bells are hitting their stride now. Ensure consistent moisture during dry spells – both plants appreciate about an inch of water per week. Mulch helps retain soil moisture and keeps roots cool.
Remove any coral bells flower stems after blooming if you prefer a clean foliage look, or leave them for the hummingbirds and winter interest. The seed heads can be quite attractive frosted with ice.
Fall Preparations
Fall is an excellent time to divide and transplant if needed. Both plants recover well from fall division in most climates. Apply a fresh layer of compost around plants – it will break down over winter and feed spring growth.
Don’t cut back foliage in fall. Both plants benefit from the winter protection their leaves provide. The leaves also catch falling leaves, creating natural mulch.
Winter Care
In cold climates (zones 3-5), a light covering of evergreen boughs or straw after the ground freezes can prevent frost heaving, which pushes plants out of the soil. Remove the covering gradually in early spring.
In milder zones, both plants may remain semi-evergreen. Simply remove any winter-damaged leaves in spring.
Design Ideas and Companion Plants
Creating a Woodland Tapestry
The combination of lung wart and coral bells forms a beautiful foundation for a shade garden, but they truly shine with additional companions. Consider adding spring ephemerals like Virginia bluebells, trilliums, or bloodroot that will bloom alongside the lung wart then go dormant as the coral bells fill in.
Ferns are classic partners. The delicate fronds of Japanese painted fern, lady fern, or Christmas fern contrast beautifully with the broad leaves of lung wart and ruffled coral bells foliage. Their similar cultural needs make them easy companions.
Color Echoes and Contrasts
Choose coral bells varieties that echo or contrast with your lung wart selection. Silver-leaved lung wart varieties like ‘Silver Streamers’ or ‘Majesté’ pair stunningly with purple coral bells like ‘Palace Purple’ or ‘Obsidian’. The silver-to-purple relationship is sophisticated and modern.
For a warmer palette, try caramel or peach coral bells like ‘Caramel’ or ‘Georgia Peach’ with green-and-silver lung wart. The warm tones glow in shaded areas. Chartreuse coral bells like ‘Lime Rickey’ or ‘Electra’ create high contrast against dark green lung wart foliage.
Container Combinations
Both plants perform well in containers, making them perfect for shaded patios and balconies. Use a high-quality potting mix with added compost. Choose a container at least 14 inches wide and deep to accommodate root systems.
In containers, you can plant them more closely than in the ground. Try a “thriller, filler, spiller” approach with a tall fern or hosta as thriller, lung wart and coral bells as fillers, and a trailing plant like creeping jenny or ivy as spiller.
Container plants need more frequent watering and fertilizing. Apply a diluted liquid fertilizer monthly during the growing season.
Rock Garden and Slope Plantings
On shaded slopes or in rock gardens, the spreading habit of lung wart helps stabilize soil while coral bells provide anchor points. Plant them in pockets between rocks where soil has accumulated. The improved drainage in these situations suits both plants well.
Add small bulbs like snowdrops, crocus, or species tulips for very early color before the lung wart blooms.
Troubleshooting Common Issues
Foliage Problems
Brown leaf edges on lung wart usually indicate too much sun or insufficient water. Move plants to a shadier spot or increase watering. On coral bells, brown edges often signal sun scorch or fertilizer burn.
Powdery mildew can affect lung wart in humid conditions with poor air circulation. Space plants properly, avoid overhead watering, and choose resistant varieties like ‘Diana Clare’ or ‘Moonshine’.
Coral bells may develop crown rot in poorly drained soil. Ensure the crown sits at or slightly above soil level, and don’t mulch directly against the crown.
Pest Management
Slugs and snails are the primary pests for both plants. They’re most active in spring and fall during cool, damp weather. Hand-pick at night with a flashlight, use copper tape barriers, or apply iron phosphate baits which are safe for pets and wildlife.
Deer and rabbits generally avoid both plants due to their hairy or tough foliage, but hungry animals may sample them. Repellent sprays can help during high-pressure periods.
Vine weevil larvae can damage coral bells roots. Beneficial nematodes applied in spring and fall control them effectively.
Flowering Issues
If lung wart flowers poorly, it may be too young (first-year plants often bloom sparsely), too shady, or overcrowded. Divide congested clumps in early spring or fall.
Coral bells bred for foliage may have insignificant flowers. If flowers are important to you, choose varieties known for good bloom like ‘Cherry Cola’ or ‘Paris’.
Propagation Methods
Division
Division is the easiest and most reliable propagation method for both plants. For lung wart, dig the entire clump in early spring or fall. Gently pull apart the rhizomes, ensuring each division has roots and several growth buds. Replant immediately at the same depth.
Coral bells division works similarly. Dig the clump, and using a sharp knife or spade, cut into sections each with several crowns and roots. Fall division is often more successful for coral bells as they’re prone to heaving if divided in spring in cold climates.
Seed Propagation
Both plants can be grown from seed, but with caveats. Lung wart seeds need cold stratification – sow fresh seeds in summer for spring germination, or refrigerate seeds for 4-6 weeks before spring sowing. Seedlings may not come true to type for named varieties.
Coral bells seeds are tiny and slow to germinate. They also require light to germinate, so press into the surface of moist seed-starting mix without covering. Hybrid varieties won’t come true from seed.
Root Cuttings
Lung wart can be propagated from root cuttings taken in late fall or winter. Cut 2-inch sections of pencil-thick roots, lay horizontally in moist potting mix, cover lightly, and keep cool until shoots emerge.
Varieties to Consider
Outstanding Lung Wart Selections
‘Diana Clare’ offers long, narrow leaves heavily silvered with excellent mildew resistance. Flowers are vivid blue. ‘Silver Streamers’ has the most intensely silver foliage of any variety. ‘Raspberry Splash’ features coral-pink flowers and heavily spotted leaves. ‘Majesté’ is nearly solid silver with pink-blue flowers.
For smaller spaces, ‘Baby Blue’ stays compact at 6-8 inches tall. ‘Sissinghurst White’ offers pure white flowers – rare for lung wart.
Top Coral Bells Cultivars
‘Palace Purple’ is the classic purple-leaved variety that started the coral bells revolution. ‘Obsidian’ has the darkest, shiniest near-black leaves. ‘Caramel’ offers warm amber foliage that tolerates more sun. ‘Lime Rickey’ brings electric chartreuse to shade.
‘Fire Alarm’ has bright red spring foliage maturing to deep red. ‘Berry Smoothie’ displays large, rose-pink leaves. ‘Silver Scrolls’ features silver leaves with dark veining – a perfect echo for silvered lung wart.
Long-Term Garden Evolution
Managing Spread
Lung wart slowly expands by rhizomes, forming colonies over time. This is generally a desirable trait – it suppresses weeds and creates a groundcover effect. If it spreads beyond its allotted space, simply dig out the excess in spring. The divisions can be replanted elsewhere or shared with friends.
Coral bells stay put but may develop woody centers after several years. Division every 3-4 years rejuvenates them and prevents the “donut effect” where the center dies out.
Succession Planning
As your garden matures, tree canopies may deepen the shade. Both plants adapt well to increasing shade, though flowering may decrease. If an area becomes too shady even for these shade-lovers, consider transitioning to more shade-tolerant plants like hostas, ferns, or wild ginger.
Conversely, if tree removal increases light, monitor for stress signs. You may need to relocate plants to a shadier spot or provide temporary shade cloth during the hottest part of the day.
Building a Plant Community
Over time, your lung wart and coral bells planting will become a stable plant community. Self-sown seedlings of both may appear – lung wart seedlings often revert to greener foliage, while coral bells seedlings are unpredictable. Remove unwanted seedlings or pot them up to evaluate.
This community will support increasing biodiversity. Early pollinators visit lung wart flowers. Hummingbirds feed on coral bells blooms. Beneficial insects shelter in the foliage. The leaf litter creates habitat for countless small creatures.
Conclusion
Planting lung wart with coral bells is one of those gardening decisions that pays dividends for decades. These two perennials, so different in texture and timing yet so similar in needs, create a partnership that’s greater than the sum of its parts. From the first pink-and-blue lung wart flowers of March to the ruffled coral bells foliage that persists into winter, this combination delivers continuous interest with minimal fuss.
What I love most about this duo is how it teaches patience and observation. You learn to notice the subtle color shift in lung wart flowers, the way coral bells leaves catch light after rain, the rhythm of growth and rest that defines the shade garden. These plants don’t demand center stage – they create a quiet, sophisticated beauty that rewards the attentive gardener.
Whether you’re planting a new shade bed, refreshing an existing one, or simply tucking a few plants into a bare spot under a tree, consider the lung wart and coral bells partnership. Start with just a few plants of each, observe how they perform in your specific conditions, and expand from there. Gardening is, after all, a conversation with your piece of earth – and these two plants have a lot to say.
Your shade garden is waiting. The lung wart will bloom before you know it.
