pulmonaria

Pulmonaria (Pulmonaria saccharata)

Bethlehem Sage, Lungwort

Part shade to full shade, medium to moderately moist moisture, humus-rich well-drained loam; tolerates clay if drainage is adequate; pH 5.5–7.0; does not tolerate full sun or dry soil in the Middle Tennessee climate.

10–18 inches tall by 18–24 inches wide; blooms in early spring (March–April in Middle Tennessee) with funnel-shaped flowers that open pink and mature to blue-violet on the same plant; silver-spotted dark green foliage is the primary ornamental feature through the growing season; spreads slowly by rhizome.

Divide clumps every 4–5 years in early fall to refresh vigor.

Native region: Not native to Tennessee; ornamental introduction from central and southern Europe.

Pulmonaria saccharata is one of the earliest-blooming perennials in the Middle Tennessee shade garden and among the most distinctive for its white-spotted foliage. The primary cultural challenge in the humid zone 7a climate is powdery mildew, which typically appears on older foliage in late summer — established practice is to shear the entire plant to the ground after midsummer, which forces clean new foliage for fall. Select mildew-resistant cultivars such as 'Majeste' or 'Trevi Fountain' when available. Unlike many shade perennials, pulmonaria is a good companion for Polystichum acrostichoides (Christmas Fern) and spring bulbs, as its bold spotted foliage covers bulb senescence effectively.
