This is one of the most aggressive Lungwort, capable of covering large areas with its green foliage. Blooms tend to be red, maybe a bit purple in it. One of my patches crashed hard after a strange winter with little snow cover and really cold temperatures but recovered from maybe root remains and seedlings. Flowering tend to be a bit on the shy side, as not all plants send up blooming stalks. They need to be handled by gloves as the foliage is rough. They self sow rapidly, and grows to mature size rapidly, so you have to keep a eye out for seedlings. Grows in sandy soil in woodland shade.

Neutral Terry On Aug 18, 2001, Terry from Murfreesboro, TN (Zone 7a) wrote:

P. rubra is a bit different from other pulmonarias. The foliage is typically not spotted, although some varieties do sport variegated foliage. The leaves are somewhat larger than other species, and the flowers remain the same color (usually pink, salmon or red), unlike most pulmonarias, which change from pink to blue, lavender or white.
