Mexican petunias do benefit from pruning, especially if they’re grown as a hedge. Cutting back the stems after flowering will encourage new growth and even more blossoms. They don’t get very tall—just 3 or 4 feet high—so keeping them trimmed back can be done usually without a ladder or other special equipment.

The color of the stems will vary depending on the light conditions—the more light the plant receives, the more purple you will find on their stems. In shadier areas, the stems will present as a solid green.
If you want to speed up the propagating process, you can create new plants from tip cuttings. Once you’ve taken your desired amount of cuttings, remove the buds, flowers, and lower leaves from the stems. Dip the ends of each stem in rooting hormone, and then plant in pots filled with peat moss and soil. Once they take root (usually after a few weeks), you can add the plants to your yard.

The Mexican petunia (Ruellia brittoniana) is a beautiful addition to a flowering backyard retreat. As a hardy perennial (you only need to plant them once), the Mexican petunia is one of several desert plants that are recommended for warm, dry climates. They are inexpensive, low maintenance, and drought-resistant. Also known as Purple Showers, the Mexican petunia’s flower petals are most commonly a vibrant violet color, but they can also be pink or white. Like daylilies, they only bloom once a day, but continuously bloom throughout the summer.
If you’re concerned about excessive spreading, you can opt to plant a sterile variety of Mexican petunia. In fact, the wild variety is not often sold since it can become so problematic. “Katie” is a popular dwarf cultivar because it doesn’t produce seed pods and therefore is not considered invasive.
Mexican petunias can be grown in pots. As long as they’re placed in a sunny spot, they grow well in indoor pots and outdoor planters alike. As a fast-growing shrub, they may need to be repotted more frequently than other plants.
The Mexican petunia plant is a fast grower and is used successfully against block walls or to surround and camouflage unpleasant looking electrical boxes and air conditioning units. If growing around an appliance, make sure you leave enough room on one side so it can be accessed for maintenance.
Transplanting Mexican petunias is best done in the fall before they go dormant in the winter. Once established in their new location, they should grow as normal and perk up when temperatures increase in the spring.

When given ideal growing conditions, Mexican petunias are not very susceptible to blight. There is also no major concern when it comes to pests.
