I have this weed in my chile patch. It's shown up every year for quite a while   
   and every year it's a little more invasive than the year before. I can cut it   
   off pretty deep, several inches, and not hit its roots. I suspect there's a   
   very deep runner or    
   something and it sends up plants from there. Round-up (desperate here) seems   
   to kill the particular plant but not the entire system and its mothership. It   
   roughly radiates outward from a point slightly outside my property, on the   
   other side of our fence.   
      
   I've never seen this before its first appearance in my garden. It's a toughie.
