Well that is what I call them .. they are a darned weed! I want to permanently get rid of them in the driveway as my poor dog steps on them and then limps !! I have pulled them, put weed icky stuff on em (like my names ? LOL) I have even tried the vinegar, dawn and water .Put tin on em to smother em. Nothing works on them darned weeds.
I am not sure of the correct name but that is what I have heard all Coloradans call em.
Any suggestions ?
Thanks !!!!
