I thought these plants were part of my garden, but as the got bigger I wasn't sure. The stems are about 1" - 2" in diameter. Thanks.
couldn't find a weed site for tx, maybe neighboring state's ag ext has a weed site? but i came across a site with pics of unidentified plants (or 'weeds'?). yours is among the pics. http://www.catnapin.com/public/WildWeeds/Weed/WeedMisc.htm
