The Story

Ruellia simplex is a vigorous, shrubby perennial known for its lance-shaped, dark green leaves and prolific, trumpet-shaped flowers that bloom from summer to frost. The species can be invasive in warm climates. This pink-flowering variety provides a continuous display of vibrant, petunia-like blossoms. Many modern cultivars are sterile or less aggressive than the parent species.
