Pulmonaria 'Diana Clare' is the current gold standard for silver-leaf, heat-loving lungworts. Pulmonaria 'Diana Clare' is a vigorous Pulmonaria longifolia hybrid discovered by our plant friend Bob Brown in 1995 at his UK nursery. Bob was so impressed with his new find that he not only introduced it but also named it after his wife, Diana Clare. The 10" tall x 18" wide clump is composed of long, pointed leaves with a spotted border that quickly ages to pure silver. The clumps are topped, starting in late February, with short stalks of flowers that open dark violet, but soon age to cobalt blue...truly superb!
