Plant Type: Perennials
Lungworts are shade plants that are often valued more for their attractive foliage than for their spring flowers. 'Cotton Cool' is a mounding variety that features silver leaves with white blotching and blue flowers. Silvery leaves have white blotching. Drooping clusters of funnel-shaped flowers appear on short stalks just above the foliage in spring. Flowers emerge pink but mature to blue, with pink and blue flowers often simultaneously present on blooming plants. Common name of lungwort is in reference to the supposed resemblance of the blotched/spotted leaves to a diseased lung.
Growing & Maintenance Tips:
Plants wilt rapidly from soil drying out when large and rooted out. Pulmonaria prefer their roots cool.Easily grown in average, medium moisture, well-drained soils in part shade to full shade. Prefers cool, organically rich, humusy soils that are kept consistently moist. Soils must not be allowed to dry out. Foliage may depreciate considerably in hot summer weather and may scorch if grown in too much sun. Although plants tolerate light morning sun, they need afternoon shade. Remove flower stems immediately after bloom. Plants spread slowly by creeping roots, but are not invasive. Divide plants in fall if they become too crowded. Plant leaves may retain some color in warm winters.
