Mexican Petunia

Mexican Petunia (Ruellia simplex) is a tough, fast-growing perennial known for its vivid purple, trumpet-shaped flowers and slender green foliage. Blooming from spring through fall, this plant provides continuous color in garden beds, borders, and mass plantings. Its upright growth habit and grass-like leaves give it a clean, modern look that complements both formal and naturalized landscapes.

Typically growing 2–4 feet tall, Mexican Petunia thrives in warm climates and adapts well to a wide range of growing conditions. It performs best in full sun to partial shade and is highly tolerant of heat, humidity, and drought once established. This plant is often used for erosion control or as a low-maintenance groundcover alternative, making it a favorite for residential and commercial landscapes alike.
