Mexican Petunia 'Purple Showers' - Ruellia brittoniana 'Purple Showers' (AKA R. twedia) is one of the toughest, showiest and most widely used Florida Friendly perennials. This cultivar does not produce seed and was found to be sterile by University of Florida research published in 2002 that was sponsored by the Department of Environmental Protection. This is important because the non sterile wild Mexican type has exploded in Florida wetlands over the last century and they are impossible to eradicate. The wild type is listed as a category 1 invasive species by the Florida Exotic Pest Plant Council. Wading birds continue to spread the seeds far and wide making them a dominate species in many of our wetland areas. Purple Showers is a wonderful sterile Florida Friendly Plant. Your garden will have no impact on the wetlands using sterile Purple Showers which is an excellent choice as it grows well just about anywhere with little or no extra water or fertilizer thus reducing your environmental impact further. No wonder it is becoming one of the most popular perennials in the south.
Disney uses Mexican Petunia 'Purple Showers' extensively for it's year round color and durability in a very wide range of water and light conditions. Here it is growing as a permanent planting in the beautiful floral display beds in the Canada attraction at EPCOT. Mexican Petunia 'Purple Showers' grows in ponds or in dry sandy soils and even tolerates coastal Florida salt air well.
