This is Pink Chi – Chi it is also known as the Mexican Petunia and Ruellia Brittoniana Flower plant. We have the purple version of this plant known as Purple Showers both of them multiply quickly, but the purple is more invasive.
We like to have a lot of blooming things in our yard to look at but also for the butterflies, bees, hummingbirds, birds, dragonflies and lizards and anything else that wants to use these plants or flowers.
There is not much telling what you might find hiding in these plants. Lately, I have been seeing a lot of baby lizards about one inch long.
