Lungwort Growing & Care Guide

Lungwort, scientifically known as Pulmonaria, is a genus of flowering plants that are often celebrated for their unique, spotted foliage and vibrant flowers. These perennial plants have found a comfortable home in many shade gardens due to their striking appearance and hardy nature. In this article, we’ll explore the world of lungwort, discussing what they are, what they look like, and where they originate from. We’ll also provide detailed information on how to grow and propagate these captivating plants.

What is Lungwort?

Lungwort (Pulmonaria spp.) is a perennial herbaceous plant that belongs to the family Boraginaceae. It is native to Europe and Western Asia but is now widely cultivated in gardens around the world. Lungwort gets its name from the historical belief that its spotted leaves resembled diseased lungs, leading to its use as a medicinal herb for respiratory ailments.

Lungwort is primarily grown for its ornamental value in gardens and landscapes. The striking contrast between the spotted leaves and colorful flowers makes it an attractive addition to shade gardens, woodland areas, or borders. The plant is often appreciated for its early bloom time, adding a burst of color to the garden in early spring.

While lungwort has a historical association with lung health and has been used in traditional herbal medicine for respiratory conditions, it’s important to note that scientific evidence supporting these claims is limited. As with any medicinal plant, it is advisable to consult with a qualified herbalist or healthcare professional before using lungwort for medicinal purposes.

What Does Lungwort Look Like?

The plant’s charm lies in its unique leaves and striking flowers. The leaves are long, slightly hairy, and often display an intriguing pattern of silver or white spots. The foliage creates a stunning backdrop for the plant’s flowers, which bloom in clusters on upright stems in the early spring.

Lungwort flowers are bell-shaped and usually change color as they mature, starting as pink buds and transforming into a brilliant shade of blue or violet when fully open, which adds an enchanting dynamic element to the garden.

Native Habitat and Invasiveness

Lungwort is native to Europe and western Asia, where they are typically found in humid woodland environments or along riverbanks. Despite their foreign origin, lungworts are not generally considered invasive in North America. They spread slowly via rhizomes, forming dense but manageable clumps.

How to Grow Lungwort

To successfully grow lungwort (Pulmonaria spp.) in your garden, follow these guidelines:

  1. Site Selection: Choose a location that provides partial to full shade. It thrives in woodland settings or areas with filtered sunlight. Avoid planting it in direct, intense sunlight, as it can scorch the leaves.
  2. Soil Preparation: Lungwort prefers moist, well-draining soil that is rich in organic matter. Prepare the soil by adding compost or well-rotted organic matter to improve its fertility, moisture retention, and drainage.
  3. Planting: Dig a hole that is slightly larger than the root ball of the lungwort plant. Place the plant in the hole, ensuring that the crown (where the stems meet the roots) is level with or slightly above the soil surface. Backfill the hole with soil, gently firming it around the roots. Water thoroughly after planting to settle the soil and provide initial moisture.
  4. Watering: Lungwort plants require consistent moisture to thrive. Keep the soil evenly moist, especially during dry periods. Avoid overwatering, as lungwort can be sensitive to waterlogged conditions. Mulching around the plants with organic matter helps retain soil moisture and regulate temperature.
  5. Fertilization: Lungwort generally does not require heavy fertilization. However, you can apply a balanced, slow-release fertilizer in early spring if the soil is poor or lacking in nutrients. Follow the package instructions for the appropriate dosage and application method.
  6. Maintenance: Remove spent flowers and trim back any damaged or yellowing foliage to encourage continuous blooming and maintain the plant’s appearance. Lungwort can be prone to self-seeding, so deadheading the flowers can help prevent excessive spreading.
  7. Division: Over time, lungwort plants may become crowded or lose vigor. To rejuvenate them, divide the clumps every three to four years in early spring. Gently lift the plant, separate the clumps into smaller sections, and replant them in prepared soil. Ensure each division has sufficient roots and foliage.
  8. Pest and Disease Management: Lungwort is generally resistant to pests and diseases. However, keep an eye out for slugs or snails, which can occasionally feed on the foliage. Implement organic slug control methods if necessary.

By following these guidelines, you can successfully grow lungwort in your garden. Remember to adapt the care routine to your specific climate and consult local gardening resources for region-specific advice.

How to Propagate

Lungwort can be propagated by division or from seed.

Division: This is the easiest method. Simply divide the plant in early spring or after the flowering period in late spring or early summer. Each division should have a good root system and several shoots.

From Seed: It can also be propagated from seeds. Collect seeds after flowering and sow in a cold frame or unheated greenhouse during fall. Keep in mind, growing from seeds may take a bit more patience as they will require a cold period to germinate and may take some time to mature.

Uses

Lungwort (Pulmonaria spp.) is a perennial plant that offers both ornamental and medicinal uses. Here are some common uses for lungwort:

  1. Ornamental Garden Plant: It is often cultivated for its attractive foliage and charming flowers. The leaves of lungwort are typically green with white or silver spots or markings, creating an eye-catching display. Lungwort plants can be used as ground covers, in borders, or in woodland gardens, adding visual interest and texture to the landscape.
  2. Pollinator Plant: The flowers are bell-shaped and usually come in shades of pink, purple, or blue. They attract bees, butterflies, and other pollinators to the garden, supporting the health and biodiversity of the ecosystem.
  3. Medicinal Herb: Traditionally, lungwort has been used in herbal medicine for respiratory ailments due to its historical association with lung health. It was believed that the spotted leaves resembled diseased lungs, leading to its use as a remedy for coughs, bronchitis, and other respiratory conditions. However, it’s important to note that scientific evidence supporting these claims is limited, and consulting a healthcare professional is advisable before using it medicinally.
  4. Edible and Culinary Uses: In some cultures, young lungwort leaves are consumed raw or cooked. They have a mild flavor and are often used in salads or as a garnish. However, lungwort should be consumed in moderation, and it’s essential to properly identify the specific lungwort species and ensure it is safe for consumption.
  5. Companion Plant: This plant is known to attract beneficial insects such as ladybugs and hoverflies. These insects help control pests in the garden, making lungwort a valuable companion plant for pest management.

While lungwort offers potential benefits, it’s important to note that the consumption and medicinal use of plants should be approached with caution. It is always advisable to consult with a qualified herbalist or healthcare professional before using lungwort or any other plant for medicinal purposes.

In conclusion, lungwort provides a delightful combination of attractive foliage and vibrant, changing blooms, making them a charming addition to any shade garden. Their easy-going nature and unique characteristics make them a joy to cultivate. With the right care and propagation practices, you can enjoy the beauty of these plants in your own garden for many years to come.
