Safety Overview
1.Pulmonaria Saccharata — At a Glance
Pulmonaria saccharata, commonly known as Bethlehem sage or spotted lungwort, is a captivating herbaceous perennial belonging to the Boraginaceae family. Native to Europe, particularly the Apennine Mountains, it has gained widespread popularity in temperate shade gardens across North America and other regions. This low-growing plant typically reaches heights of 12-18 inches with a similar spread, forming attractive clumps.
Its most striking feature is the foliage: ovate to lanceolate leaves, often broadly elliptic, which are dark green and intricately adorned with prominent silver-white blotches or spots, creating a unique speckled effect that persists throughout the growing season. The specific epithet 'saccharata' refers to these sugar-like spots.
In early spring, Pulmonaria saccharata produces clusters of funnel-shaped flowers at the tips of its stems. These delicate blooms exhibit a fascinating color transformation, typically emerging pink in bud and gradually maturing to shades of blue, purple, or sometimes white as they open. This color change is often attributed to shifts in pH within the flower cells.
The blossoms are a valuable early nectar source, attracting various pollinators like bees. The plant thrives in cool, moist, well-drained soils rich in organic matter and prefers partial to full shade, making it an excellent choice for woodland gardens or shaded borders. Its natural distribution in Europe typically encompasses deciduous forests and rocky slopes, where it benefits from the protection of tree canopies.
It is a hardy species, generally adaptable to USDA hardiness zones 3-8, and is known for its resistance to deer and rabbits.
