I have this plant growing in my backyard near Houston, TX (UDSA Zone 9a). I been letting it grow because I have no idea what it is. It starting to look like just another weed. Can anyone identify this please?
It looks like grain sorghum to me, and probably arrived in your yard via the birds, as it is a popular component of commercially packaged bird feed. The fact that it's near a fence would tend to give support to this theory!
