Can someone help me identify this weeds or grass and advise me on how to get rid of it. The weeds/grass has taken over my whole front yards. link to the pics: http://imgur.com/7nXj4EI,gBDuNIg,FRGIuAd,Hfy392J,Dh92KyC,Gnv9EWG,IbkN2ip,Cq11nv7#0 I live in an urban area in southern Louisiana if that help with identifying it. Thanks!

Update on this...it has grown even taller and developed a rather ungainly branching habit. It's just starting to flower with tiny white flowers. Can anyone help ID it now?

There are hundreds of yellow-flowered Asteraceae which look superficially dandelion-like. Your photo is taken from too far away to see much detail in the leaves and also you have not said where the plant is located geographically. So an identification is pretty tough. Maybe you could post again when there are some flowers (are they even yellow?) and show us a closer view of the foliage. For example, I can't tell if the leaves are smooth or not.

Not to be too nit-picky, but the issue with Norway maple is not that it is a "trash tree" or any other negative attribute. They are handsome, vigorous trees. The issue is their invasiveness here in N. America. And it's a real issue, this tree truly being capable of outcompeting not just individual native trees, but whole plant communities. Just saying.....there's a reason several million of these things got planted all over the US and Canada. But time has shown that the invasive potential is just too great with this one. And yes, I am well aware of the other "issues" with the tree-its very heavy shade, tendency towards shallow roots, its tendency to develop girdling roots in transplanted individuals. But none of those factors absolutely preclude our using this tree. The invasiveness however, does.
