Looks like the native (L. horrida/urticoides) to me.

It looks like it but hard to tell with any exactitude. There are so many of them . There are several different native ones that differ slightly too.

I think the leaves have a coarser feel and when crushed their is a stronger smell with the horrida. It also makes more blackberry like seeds. There are some look alike L. camera.

One other factor to consider is the relatively greater cold hardiness of the L. urticoides native versus the L. camera varieties that are usually tagged as annuals in north Texas. I suspect most L. cameras from central Texas north sitting unprotected in exposed locations were done in by the long single digit freeze last February. Our 'Dallas Red' that had survived ~5 years in a very well sheltered spot didn't stand a chance in spite of being well covered, while the L. urticoides out in the open yard with just a coating of snow for protection were all unphased. Doubt the OP plant would have survived in much of Texas this year if it had a strong L. camera ancestry.

Still think it bears a strong resemblance to our known L. horrida/urticoides:
