Pulmonaria ‘Trevi Fountain’
This superb, brightly silver-spotted beauty will give rise to profuse clusters of large cobalt-blue flowers in spring. A stunner! We feel it is our best, true dark-blue and grows into a magnificent landscape specimen. The roots of this plant are in P. longifolia, the best form for the south, according to John Elsley.
