Pulmonaria NOVA 'Cobalt'

Pulmonaria NOVA® ‘Cobalt’ is a named selection of Pulmonaria saccharata, grown for deep cobalt-blue flowers above dark green foliage. Terra Nova reports foliage about 12 inches high, flowering stems about 14 inches high, and a spread near 18 inches, so the flower stems may rise above the leafy clump. ## Garden Use Use this clumping perennial in a shaded border or woodland planting, where its vivid flowers and deep green leaves provide an early-season accent. The [Terra Nova product page](https://www.terranovanurseries.com/product/pulmonaria-nova-cobalt/) gives April–May bloom, zones 4–9, and tolerance of full sun through shade; its [2026–27 catalog entry](https://www.terranovanurseries.com/other/catalogs/digital/2026-2027/files/basic-html/page151.html) identifies the cultivar as Pulmonaria saccharata NOVA® ‘Cobalt’. The grower describes it as fast-growing, deer-resistant, and attractive to hummingbirds. ## Growing Conditions Part shade is a dependable choice, especially where the soil remains cool and moist. Use humus-rich, well-drained ground and water during prolonged dry weather. The plant’s foliage height and its taller flowering stems are reported separately in the nursery profile. ## Maintenance Remove spent flower stems after bloom and trim damaged foliage as needed. Keep healthy leaves through the season so the clump continues to cover the soil and support next spring’s growth.
