lungwort 'Diana Clare'


Pulmonaria 'Diana Clare', commonly known as lungwort, is a perennial plant known for its striking foliage and lovely spring flowers. This variety features leaves that are heavily silvered, providing a luminous quality to the plant. The leaves are ovate or heart-shaped with a rough texture and emerge with a unique silver frosting that persists throughout the growing season, creating a shimmering effect in the garden. The lungwort produces clusters of delicate flowers that emerge in shades of violet-blue, creating a beautiful contrast with the silvered leaves. During the blooming period, the flowers can change color from pink to blue as they age, adding further intrigue to its display. These bell-shaped flowers are arranged in clusters on stems that rise above the foliage, providing a pop of color in early spring when not many other plants are in flower. As the season progresses, the silver foliage of the 'Diana Clare' lungwort remains an attractive feature in the garden, even after the flowers have faded. Its textured leaves can become a backdrop for other plants, or it can serve as a focal point in shade gardens or woodland settings. The visual appeal of 'Diana Clare' lungwort makes it a favored choice for gardeners looking to add both foliage interest and early-season blooms to their shady garden spots.

  • circleLife cycle

    Lungwort 'Diana Clare' starts life as a seed, which germinates in moist, well-drained soil in partial to full shade. The seedlings develop into a rosette of leaves and gradually establish a deep root system. As the plant matures, it produces broad, silver-spotted leaves and, in early spring, sends up stems bearing pink-to-blue funnel-shaped flowers which attract pollinators. After flowering, seeds are produced and dispersed, either by wind or wildlife, to begin a new generation. In the summer, the plant enters a semi-dormant phase to conserve energy, especially important in hotter climates. Over time, the clumps may become crowded and can be divided in late summer or early autumn to rejuvenate growth and spread the plant.

      Spring to Summer

    • Propogation: The Pulmonaria 'Diana Clare', commonly known as Lungwort, is typically propagated through division. This popular method is done in either spring or fall when the plant is not in active bloom. To propagate by division, carefully dig up the Lungwort, making sure to get as much of the root system as possible. Gently separate the plant into smaller clumps, ensuring that each clump has several healthy shoots and a portion of the root system. Replant the new divisions promptly, spacing them about 12 inches (approximately 30 centimeters) apart so each has sufficient space to grow. Water the new plants thoroughly to help establish them in their new location. This method allows for the quick establishment of new plants and is ideal for expanding the garden or sharing with fellow garden enthusiasts.
