Ruellia caroliniensis (Carolina Wild Petunia)

Ruellia caroliniensis (Carolina Wild Petunia) is an unbranched, spreading perennial boasting a profusion of trumpet-shaped, petunia-like, light purple flowers borne in axillary clusters of 2-4. Blooming for weeks from early to late summer, the blossoms have a slender corolla tube and 5 petal-like lobes. Each blossom lasts a day or two, but new flowers form in succession. They provide nectar for bees and butterflies.

Blooming for weeks from early to late summer, the blossoms have a slender corolla tube and 5 petal-like lobes. Each blossom lasts a day or two, but new flowers form in succession. They provide nectar for bees and butterflies. Carolina Wild Petunia serves as a host plant for Buckeye butterfly caterpillars. The blossoms give way to seeds borne on hooked projections. The opposite leaves, 2-4 in. long (5-10 cm), are rich green, oval and medium in texture. A strong grower, Carolina Wild Petunia can spread, as it readily reseeds itself. Great as a flowering ground cover, for mass plantings, hanging baskets or cascading down a wall.

  • Grows up to 6-12 in. tall (15-30 cm) and 12-24 in. wide (30-60 cm).
  • Performs best in part shade to full shade, in dry to moist, clay, loam or sandy, well-drained soils. Drought tolerant once established.
  • Attractive to butterflies and somewhat unpalatable to deer.
  • Virtually pest and disease free.
  • Propagated by seed or cuttings. Seeds may be planted immediately after collection or stored and sown in spring. Store seeds dry in an airtight, refrigerated container.
  • Native to eastern North America.
