Not sure if I've got the right plant or not...mine's not invasive. It is a native--I dug up the first one in a rent-house lawn. It's been with me through three moves, and seems to thrive without being the slightest bit invasive. Doesn't look like the other ruellias I've seen, though.

extremely invasive. I planted one then spent years weeding them out of everywhere and still would be but I moved. Perhaps roundup might have killed it but I didn't want to use it. It should really be on an invasive species list in SC.

This plant is found mostly in the cracks and crevices around the patio and walkways. It's a nice plant - just appears in inconvenient places. I was spraying some Roundup on some grass and sprayed some on a few of the wild petunias. In a few seconds I started hearing some very noticeable snapping or popping sounds. At first I thought it was some sort of snapping bug or grasshoppers that the spray had irritated. Something was even hitting me and it was ricocheting off of things nearby. When I looked closely I found that the seed pods on this plant were popping open and ejecting a seed. They were traveling several feet. I assume that the moisture in the spray must have made the plant react as if to rain and thus spread its seeds. I have not seen this interesting feature reported in my readings about wild petunias. Has anyone else observed this?

our backyard is covered in this flower. thought it was a weed at first and tried to pull a bunch, but then one bloomed :) I have since been trying to spread them around in the places I want them to be. I'm so happy they volunteered in our yard.

I have my Ruellia in a planter on my patio. It is at least 3 ft. tall. It blooms each morning before sun-up and then the
blooms fall off around mid-afternoon, then the process is
repeated the next morning. Is this normal? I love the plant.
I look forward each morning to see how many blooms I have.
