Lungwort: Your Shade Gardens Best Friend!

Lungwort: Your Shade Gardens Best Friend! - Nature Hills Nursery

Charlotte Weidner |

Maybe not the best name, but back in the day, folks named things as they saw them. And the genus Pulmonaria means “lung” as the spotted leaves resemble diseased lungs. Sorry, we know that the visual didn’t help! But trust us when we assure you that these are lovely perennials!

The lung-theme is continued due to the medical properties it possesses - Having been used in the treatment of coughs and diseases of the chest!

Luckily, these unique shade garden plants also go by the names Bethlehem Sage, Jerusalem Cowslip, Jerusalem Sage, Mary's Tears, and Our Lady's Milk Drops! Members of the family Boraginaceae, Lungworts are native to Europe and western Asia.

Odd name aside, the Lungwort is a fantastic garden perennial and very easy to grow! Learn about how to utilize these incredible flowering perennial plants for your landscape here!

Lovely Lungworts!

Lungworts are perennial plants that are not only very attractive, but they are hardy, resilient, and easy to grow! They spread by their slow creeping rhizomes, yet are not invasive! Politely spreading and forming clumps of silver-speckled leaves.

Lungwort is a cool plant that emerges early in spring and immediately sends up fuzzy leaves, and flower stalks follow soon thereafter. Flowers are born on short stems just above the foliage with fine-textured flowers that are typically blue and or pink in color, and last for about a month.

Raspberry Lungwort

Flowering Lungwort will provide clusters of brilliant blue, purple, pink, or even white blossoms in the spring. Because the flowers change colors as they open and age, some selections exhibit multiple colors at the same time!

One perk of these showy spring blooms is flocks of early emerging bees, butterflies, and other beneficial pollinators! Bumblebees are especially attracted to these blooms, providing these endangered species with plenty of pollen and nectar resources! You’ll even see a curious hummingbird or two arrive to check out the nectar-rich little bell-shaped blooms!

After the long-lasting blooming period finishes, the plant transforms itself into an attractive foliage plant! When the flowers are done, the entire plant begins to transform itself from a small flowering plant into a bold and beautiful foliage plant. New leaves begin to emerge that are larger and more robust. The colorful, speckled leaves remain wildly showy throughout the spring, summer, and fall seasons!

Varieties of Lungwort at Nature Hills

  • Cevennensis Lungwort - Narrow silver-spotted leaves and striking dark violet-blue funnel-shaped flowers held in clusters that balance daintily above the foliage.
  • Twinkle Toes Lungwort - Petite plant with periwinkle blue flowers and circular clusters of tubular flowers.
  • Raspberry Splash Lungwort - Raspberry/fuchsia-hued flower clusters with fuzzy blue-green and silver-spotted leaves!
  • Mrs. Moon Lungwort - Red buds open to color-changing pinks, violets, purples, and blues rising above fuzzy green leaves spattered in silver freckles!

Where is the best place to plant Flowering Lungwort?

Lungwort Infographic

Lungworts are great for a first-time gardener! These easy-to-grow perennials love part shade/partial sun in cooler climates and full shade in the warmer end of their hardiness zone range of USDA growing zones 3 to 9.

Plant these sun-shy garden jewels in your moist, rich, fertile, well-drained garden beds and borders. Best in neutral to alkaline pH soil, they appreciate a layer of mulch spread 3-4 inches deep around their roots. They love having cool, moist root systems, and mulch is the best way to keep them happy!

Fertilize every spring with a flowering plant and perennial fertilizer to keep them blooming their very best! Deadhead as soon as the blooms fade to clean up their mounds. It is always a great idea to remove the old flower stems right down to the ground and allow the incredible foliage that takes over to punch up your garden borders.

Deer and rabbits seldom bother these woodland plants.

What do you do with Lungwort in the fall?

These herbaceous perennials die back as soon as the frost kills back the tops of the plant. As soon as the foliage yellows or is killed back in the autumn, trim the stems to the ground and remove all the leaves and debris from the area.

To prevent issues like powdery mildew, slugs, and snails, remove all leaves and debris from the area after pruning.

Top with a layer of compost and/or mulch for the winter, and water your plants in well one last time before winter.

Dividing Lungwort Plants

Every 3-5 years or so, fall is also a great time to divide your Lungwort clumps to keep them from overcrowding. This simple chore gives you 2-3 new plants to use elsewhere in your garden, or share with eager friends, family, and neighbors!

  • Simply dig all around the plant's perimeter with a sharp spade, pushing it straight down
  • Then, using the spade or a garden fork, lift the roots gently out of the ground
  • Shake off any excess soil and look at the root system to gauge where best to divide and how many parts you can divide the roots into
  • Carefully use your spade or a garden knife to cut the crown into sections. Do so quickly so the exposed roots do not dry out
  • Plant your new perennial plantlets, backfill, and tamp the soil down gently but firmly
  • Water in very well and top with a layer of mulch

Where can you use Lungwort plants in the landscape?

The Lungwort is made for the shade! To add texture and patterns to your shaded area, where the leaves shine beneath the canopy of trees and larger shrubs. Use Lungwort to brighten up your borders or as edging for garden beds in the dappled understory.

  • Pink, Blue, Violet & Purple Color-Changing Flowers
  • Long-Lasting Bloom Time
  • Beloved By Pollinators
  • Fuzzy Stems & Foliage
  • Unique Silver Speckled, Splotched Green Leaves
  • Full/Part Shade, Dappled Sun & Part Sun Locations
  • Smaller-Scale Low-Growing Perennial

Plant other understory plants with Lungwort for a varied and relaxing shade garden! Once established, Lungwort can be a drought-tolerant and eye-catching foliage plant that’s great when mixed with other shade-lovers such as lacy Ferns, pretty Primroses, Astilbe, or dramatic Hosta's. Or with larger perennials like Barrenwort, Brunnera, and Ligularia, or smaller plants like Corydalis and fine-textured Bleeding Hearts work just beautifully with the coloration and texture of these unique perennials!

In their native habitats of woodland edges, moist Rock gardens, dappled understories, and along the banks of brooks and streams, they shine beneath the canopy of large trees. Use these low-growing space-saving plants as single specimens and accents, or go plant long rows as edging and unique facer plants!

Lungwort has been prized as landscaping ornamentals and medicinal plants in herb gardens, Knot Gardens, and potager plantings! The silvery-speckled leaves are, of course, perfect for adding a special shimmer to a Moon Garden!

Their convenient size makes them ideal as container garden plants and as planter filler, spreading politely and filling bare ground like living mulch. Carry this perk into your garden beds and borders by using their spreading nature to fill in around larger plants and shrubs like Roses or as facer plants around leggy shrubs and trees!

You’ll love the silvery finishing touch that Lungwort provides!

Frequently Asked Questions

Does lungwort spread?

Yes, lungwort spreads slowly through creeping rhizomes but remains well-behaved and non-invasive. The plants politely form expanding clumps of attractive silver-speckled foliage over time rather than aggressively colonizing garden areas. This controlled spreading habit makes lungwort an excellent groundcover choice for shade gardens where you want gradual coverage without worrying about it overtaking neighboring plants.

Is lungwort a perennial?

Yes, lungwort (Pulmonaria) is a hardy perennial that reliably returns each year. These easy-to-grow plants emerge early in spring with fuzzy leaves followed by colorful flower clusters that bloom for about a month. Lungworts spread slowly by creeping rhizomes to form attractive clumps without becoming invasive. Plant them in shade gardens where they'll provide consistent spring color and foliage interest year after year.

Is lungwort invasive?

No, lungwort is not invasive. These perennials spread slowly through creeping rhizomes and form polite clumps without aggressive spreading behavior. Unlike truly invasive plants, lungwort stays where you plant it and gradually expands at a manageable rate. Plant lungwort confidently in your shade garden knowing it will behave well and won't overtake neighboring plants.

Is lung wart a perennial?

Yes, lungwort (Pulmonaria) is a hardy perennial that returns year after year, emerging early each spring with fuzzy leaves followed by colorful flower clusters. These reliable shade perennials spread slowly by rhizomes to form attractive clumps without becoming invasive. They bloom for about a month in spring, producing blue, pink, purple, or white flowers that often display multiple colors simultaneously as they age. Plant lungwort in partial to full shade with moist, well-draining soil for best results.

Is lungwort a weed?

No, lungwort (Pulmonaria) is not a weed but rather a valuable perennial for shade gardens. While it spreads slowly through creeping rhizomes to form attractive clumps, lungwort is not invasive and stays well-behaved in the landscape. These hardy plants provide early spring flowers that attract beneficial pollinators like bumblebees and butterflies, plus distinctive silver-spotted foliage throughout the growing season. Plant lungwort in partial to full shade areas where you want reliable, low-maintenance ground cover that won't overtake your garden.

Is lungwort evergreen?

Lungwort is not evergreen and behaves as an herbaceous perennial in most growing zones. The plant emerges early in spring with fresh foliage, flowers for about a month, then the leaves remain attractive through summer before dying back to the ground in fall. In zones 3-8, you can expect the spotted silver foliage to provide excellent ground cover from spring through fall. Cut back spent foliage in late fall or early spring to make way for new growth.

Is lungwort poisonous?

Lungwort (Pulmonaria) is not poisonous and is actually considered safe for humans and pets. Historically, this perennial was used medicinally to treat respiratory ailments, indicating its non-toxic nature. The plant's common names like Bethlehem Sage and Jerusalem Sage reflect its long history of safe cultivation in gardens. You can confidently plant lungwort in family gardens and areas where children and pets play.

Should you cut back lungwort in the fall?

You should cut back lungwort foliage in late fall after the first hard frost, or in early spring before new growth emerges. Remove all old leaves to ground level to prevent overwintering of fungal diseases and encourage fresh, healthy foliage in spring. In zones 3-8, this timing typically falls between November and December, depending on your location. Use clean pruning shears and compost the healthy foliage, but discard any diseased leaves in the trash.

Do deer eat lungwort?

Lungwort (Pulmonaria) is generally deer resistant due to its fuzzy, textured foliage that deer find unpalatable. The coarse, hairy leaves and bitter taste make it an excellent choice for shade gardens in areas with heavy deer pressure. However, during severe winter conditions or drought stress, hungry deer may occasionally browse any available vegetation. Plant lungwort in your shade borders with confidence, but consider additional protection if deer populations are exceptionally high in your area.

Does lungwort like sun or shade?

Lungwort thrives in partial to full shade conditions and actually prefers protection from hot afternoon sun, which can scorch its distinctive spotted foliage. These hardy perennials (zones 3-8) naturally grow in woodland settings and perform best with morning light and afternoon shade. In deep shade, lungwort will still grow well but may produce fewer flowers. Plant lungwort in areas that receive 2-4 hours of morning sunlight followed by shade for optimal flowering and foliage health.
