Many people consider this plant VERY invasive. I have to admit I am constantly doing battle with it in my potted plants, but it thrives under the cedars where nothing else seems to want to grow.

When my sister, who lives in the Houston area, talked about getting some of this from me, I didn't recommend it. It comes up all over the place from seeds and can show up in the unlikeliest places. In my part of dry Texas with sufficiently cold winters to kill it, it's easy enough to keep it in check, but I think the warmer, wetter conditions in Houston might make this a nuisance plant. For me, though, this is a great filler plant to provide green contrast among the other plants in hanging baskets. I'd recommend it for anyone who has cold winters to kill off the plants. It's easy enough to remove the extras that survive in neighboring pots. It might be something of a nuisance in a greenhouse situation. You might be fighting seedlings everywhere. I wish I had a greenhouse to test that :).
