An interesting and extremely hardy wildflower. Grows in sun or shade.
Wild Petunia (Ruellia humilis)
When we moved in to our house 30 yrs ago I needed a plant that I couldn't kill. I got some wild petunias and Mexican petunias. They have not disappointed. Could become invasive but I just pull it out. They root easily from chopping them back and sticking in a jar. Ignore them abit add water when needed to the container. I even have a pink variety! The ground cover variety, which I thought was the wild petunia does great in the shade and propagates easily as well. I don't ever want to give up on them cuz they have never given up for me. A loyal wildflower.
