Description
Wild Petunia, or Ruellia humilis, is a charming native wildflower found throughout the eastern United States. Despite its name, it’s not related to traditional petunias but is instead a member of the Acanthaceae family. This low-growing perennial typically reaches about a foot in height and flourishes in dry, sandy soils or well-drained loam, making it an excellent choice for sunny areas, prairie restorations, and rock gardens.
Its lavender, trumpet-shaped flowers bloom steadily through the heat of summer, drawing in native bees, butterflies, and even hummingbirds. Wild Petunia also serves as a larval host plant for the Common Buckeye butterfly, adding important ecological value. While this hardy plant is a reliable bloomer and self-seeder, it can spread aggressively, so gardeners may want to manage its growth in smaller garden beds. It is ideal for naturalizing and supporting pollinators.
Also known as: Prairie Petunia and Fringeleaf Wild Petunia.
