Purple Showers is becoming the most popular perennial in Florida for good reason. It is very Florida Friendly as it grows in wet or dry sites without irrigation, requires no fertilizer, has no pest problems and it attracts butterflies. Sulfur butterflies are a regular visitor to these plants. Purple Showers has double the number of chromosomes as the wild Mexican Petunia. Currently, sterile Purple Showers only comes in one color but Rosanna Freyre, Ph.D. of the University of Florida has figured out a way to breed other sterile forms and colors. In the coming years we will have more choices. Read the last paragraph of this article Breeding Brilliance.

Mexican Petunia with 1 day per week watering in full sun 3 yr old plant after 2010 Jan freeze in August

This is a three year old Purple Showers that receives one day a week watering under the Tampa rules and no fertilizer. It is growing in full sun in a median setting with bark and rock mulches covering plastic. The plant was damaged by the January freezes but recovered quickly. You can see that it is clump forming and many folks point this out as aggressive behavior but that can be a good thing if you are trying to replace turf with larger beds of carefree flowering plants. Want to remove them from and area? Three successive sprayings of roundup at four week intervals will kill the plants. This is the same recommendation for other plants that store a lot of energy in their roots like cattails. More information on Purple Showers.
