How to Grow Mexican Pansies

Overview

The Mexican pansy (Ruellia brittoniana) is more commonly called the Mexican petunia because of its striking resemblance to the annual flowering plant. Mexican pansy is a perennial flowering shrub that grows to 3 feet tall and thrives in heat and sunshine. Blooming with blue-purple flowers, from late spring through early fall, there are also white, pink and dwarf cultivars. Mexican pansy attracts butterflies, is disease- and pest-resistant and grows well in containers. If you are looking for a low-maintenance plant, and you live in USDA hardiness zones 8 through 10, consider the Mexican pansy.

Step 1

Water to keep the soil slightly moist (the moisture in the soil should be similar to a well-wrung sponge) during the growing season. Allow the soil to dry out between waterings in the winter.

Step 2

Fertilize the Mexican pansy once a month during the growing season with a 10-10-10 fertilizer, at the rate suggested on the label for the size of your plant.

Step 3

Cut the stems back halfway after flowering and the Mexican pansy will rebloom.

Tips and Warnings

  • Mexican pansy is listed as a Category 1 invasive species by the Florida Exotic Pest Plant Council. Grow your Mexican pansies in pots to prevent their escape into the wild.
