Wild petunia is a resilient native perennial found in dry, rocky soils and open woodlands across parts of the central and eastern United States. In Pennsylvania, it is considered endangered and is restricted to several south-central counties where it is quite rare and lives on limestone barrens and quarry waste. Its lavender, trumpet-shaped flowers with flared lobes resemble garden petunias and serve as a valuable pollen source for bees and other pollinators. Its hairy stems and leaves help it withstand drought and other unfavorable conditions. Blooming from late June to August, it attracts butterflies and long-tongued bees, contributing to the health of local ecosystems.
