How to identify Red ruellia (Ruellia elegans)

Red ruellia, also known as Wild petunia

Red ruellia is marked by its visually striking bright red trumpet-shaped flowers, which grow on wand-like stems approximately 6 to 8 inches (15 to 20 cm) tall. The flowers display a distinctive arrangement with the upper petals flaring outward and backward, and the lower petal curling outward and downward. This species supports a foliage that forms a soft green mound roughly 12 inches (30 cm) high and 24 inches (61 cm) in diameter, with a somewhat fuzzy texture. Despite being sensitive to severe cold, it can endure mild frosts. Red ruellia's propensity to reseed and spread renders it prolific in favorable conditions.
