Virginia Bluebells cultivar

Mertensia virginica

Spring ephemeral perennial

V Written by Editorial Team · Updated January 2026

Mertensia virginica is a spring ephemeral native to rich floodplain woods and deciduous forests in eastern North America. Its pink buds open to clusters of bell shaped blue flowers that glow in shade. Plants reach 18 to 24 in tall and 12 to 18 in wide. Bloom typically peaks from April to May across much of North America. Foliage yellows and dies back by early summer. It pairs well with later emerging shade perennials. It thrives in moist, humus rich, well drained soil in partial to full shade.
