Ruellia simplex, commonly called Mexican petunia or Texas petunia, is a vigorous, shrubby, woody-based, rhizomatous perennial that is grown as an annual north of USDA Zone 8. It is native to Mexico, but has escaped gardens and naturalized somewhat aggressively in parts of the southeastern U. S. from South Carolina to Texas plus Hawaii, Puerto Rico and the U. S. Virgin Islands. It typically grows to 3-4’ tall in the wild, but to 2-3’ tall in gardens. Plants branch from the ground into several woody-based stems clothed with elongated, linear, willow-like, dark green leaves (to 6-12” long and ¾” wide) that are often tinged with purple. Tubular, trumpet-shaped, 5-lobed, petunia-like, lavender to violet flowers (to 1.75” long) bloom from the upper leaf axils in loose purple-stemmed clusters (long-stalked cymes). Each flower blooms for only one day. Best flowering occurs in the deep South near the temperatures of its Mexican origin where flowers may appear from May to November, but sometimes year round. Flowering is very respectable but less frequent when plants are grown as annuals in northern gardens, but will typically bloom from May to September. Flowers are followed by bean-like pods (to 1” long) which explosively dehisce mature seed in all directions.

Considerable confusion has existed over the years as to the correct specific epithet for this plant. It is been given a number of different names, including R. brittoniana, R. coerulea, R. malacosperma and R. tweediana. At this time, Ruellia simplex is the preferred specific epithet because it has been determined that this was the name first given to this plant in 1870 when it was described in Cuba, and accordingly that name has priority.

Straight species is rarely sold, but several established cultivars (none patented) are regularly sold (pink, purple or white flowers in tall and dwarf forms).

Genus name honors Jean de la Ruelle (1474-1537), French herbalist and physician to Francois I (1494-1547) who was king of France from 1515 until his death in 1547.

Specific epithet of simplex is in reference to the leaves being simple.

‘Purple Showers’ is a vigorous, upright, Mexican petunia (also called Mexican blue bell) that typically grows in a clump to 3-4’ tall. Tubular, petunia-like flowers (to 1.5”) bloom freely from the leaf axils from late spring to frost (sometime year round in USDA Zones 8-10) on greenish-purple stems clad with linear, willowy, sword-shaped, green leaves. Flowers last only one day, but plants often produce an impressive non-stop succession of bloom. This cultivar that is sterile and will not produce seed, but can still spread aggressively by rhizomes and floating pieces of root. Considered by some experts to be much less invasive than the non-sterile Mexican species. Missouri Botanical Garden Plant of Merit
