Mertensia is a plant genus comprising a few dozen species of herbs. One species that is particularly popular among gardeners and landscapers is Mertensia virginica. This perennial flowering herb is native to the eastern region of North America and is commonly known as Virginia bluebell. It grows 1 to 2 feet in height and spreads a similar width. Its foliage consists of large basil leaves that droop lazily around trumpet-shaped violet flowers, which bloom in early spring. Its compact form and showy flowers make it an ideal plant for beds and borders, especially in native gardens or rock gardens.
There are several things to consider when planting and growing the Virginia bluebell. The condition of the soil, the climate, and certain pests or diseases can affect the health of Mertensia virginica.
