Roy Davidson lungwort forms an attractive, 8" to 12" high clump that slowly spreads to form a ground cover without being aggressive and overtaking other plants. Its leaves are heavily spotted with silver and the flowers, borne in loose clusters, start out pink and fade to a pale powder blue. This variety is more tolerant of heat and humidity than other varieties as long as soil is kept moist.
Grown as much for their attractive leaves as their flowers, lungworts look best grown in masses as a shady ground cover or combined with hostas, hellebores and ferns in a shady garden. The foliage remains attractive all season as long as the soil isn't allowed to dry out. You can rejuvenate a ragged patch by cutting the stems back by half after flowers fade. The genus name Pulmonaria and common name lungwort refer to the spotted foliage, considered to resemble a diseased lung. (It was once believed that if a plant resembled a particular body part, it had the ability to cure ailments associated with it; pulmonaria was used to treat respiratory problems.)
