Planted one in a north flowerbed. Lost lower foliage through the season. Died over a fairly mild winter. Would not recommend.

PULMONARIA 'Roy Davidson' - Short 12". Plant 24" apart. zone 4-8. Long narrower blue/green leaves are splashed with dots of silver. Pink flowers age to vivid blue. Very early flowering, they welcome us as the snow melts aways. Prefers moist rich soil.

General Information:
Fabulous shade plant with semievergreen foliage which remains attractive. Mounding habit will spread out to make a beautiful foliage display without being aggressive. Works well under deciduous trees and along woodland pathways. Excellent with bulbs or under trees. New introductions are constantly expanding the choices in leaf coloring.
