Mertensia virginica, commonly known as Virginia Bluebells or Virginia Cowslip, is native to east North America. In its native habitat it grows at deciduous woodland edges and openings and river floodplains. Mertensia virginica is synonymous with Mertensia pulmonarioides.

The etymological root of the binomial name Mertensia is named after Franz Karl Mertens (1764-1831), a German botanist. Virginica is derived from the Latin meaning ‘from Virginia, USA’.

The landscape architect may find Mertensia virginica useful as an attractive groundcover deciduous perennial, suitable for light shade.

Ecologically, Mertensia virginica flowers are attractive to pollinating insects, particularly butterflies and moths.
