A widespread North American native, Ruellia humilis (Wild Petunia) is a herbaceous perennial of upright to somewhat sprawling habit boasting a profusion of tubular, bell-shaped, petunia-like, lavender to purple flowers, 3 in. long (7 cm). Blooming for months from late spring to fall, the blossoms are borne singly or in clusters in the upper leaf axils. They attract bees and butterflies. The foliage of lanceolate, olive green leaves, 4 in. long (10 cm) is covered with small hairs. This plant reseeds readily. It is a wonderful addition to prairies and meadows, native plant gardens or rock gardens.

  • Grows up to 24 in. tall and wide (60 cm).
  • Performs best in full sun or part shade, in average, dry to medium moisture, well-drained soils. Drought tolerant once established.
  • Attractive to butterflies and somewhat unpalatable to deer, rabbits and livestock.
  • Virtually pest and disease free.
  • Native to eastern and central United States.
