| In one of my raised perennial flower boxes grows this noxious weed that travels on runners and pops up rosette type plants. Last fall I worked for hours and rid the box of all in sight...now they are back in full force.They grow under and around every other plant as well as in bare spots.
Can somone please ID for me and suggest how to get rid of these things ???
Thank you for your help.

| Have you ever seen it flower?It kinda looks like evening primrose to me but if it is it should have gotten a large yellow flower. |

| If it spreads by runners, try dipping one of the heads in straight-up weed killer. just let it sit there, soaking in it. Maybe it will kill the entire length of runners. someone suggested that for my weed grass and it worked... |

| It looks like a sickly ajuga. Did you spray it with a herbicide by any chance?

Agree, it looks like ajuga; mine put up pretty pink and purple flowers in spring and early summer. I've not thought of them as invasive, just good ground cover. I plant lillies and daffodils in the same beds and they do fine. |

| I am going to try the weed killer...thank you for that nteresting suggestion Suddenly Spring !
I did think it was Ajuga, but no it has never put up a single flower of any kind or color. It is just nasty and intertwines in all roots and plants. |

| Ajugas don't have root systems like that. (And ,by the way, the root system pictured wouldn't be described as a "taproot".) It's certainly not an ajuga. |

| They are a terrible blight...I just discovered this morning, that when I moved 2 little seedlings from this flower bed in May I apparently brought them with me to an area they were never in before .I have now found several in there thriving !They are extremely hardy ! I still have no clue to their identity ! |

| If you pulled it all up last year and it still came back it is probably re-sprouting from the root scraps that were left behind. This is one of those situations where an herbicide is the way to go. |

| Schimebe,
It cannot be Plantago, which is a monocot.
This plant is clearly a dicot (leaves with reticulate veins) |

| If you let it grow and bloom then you would probably get the right answer. It appears it can get tall as indicated by the cut stems in the first picture. Maybe some kind of aster or goldenrod but with juvenile growth and roots to go on, it is hard to give a good answer. |

| The plantogos I know are NOT monocots; they are in the family Plantaginaceae; clearly dicots, grouped near the valerains mentioned by GSG.
Corn salad: http://www.floridata.com/ref/V/vale_loc.cfm
is an annual and I've not been able to find anything that would indicate it's invasive, or that it has such an impressive root structure.
Agree with hcm that a flower would be helpful to ID your plant, though maybe not helpful if you're trying to eradicate it. |

| I would think that it is a Dock or Rumex of some flavor? I am not sure. I dont think anyone in this forum has ever seen Ajuga though- it is very far from it, it has tiny little fiborous roots. Dont let these people put crazy ideas in your head. |

| I did let it grow...I let it grow all summer...it never gets any taller or flowers, it is just a rosette that goes from tiny to much larger !
Very frustrating thing it is !!! I have never seen anything like it. |

| There are Rumex and sorrel that can be invasive; most say they bloom in June or July.
Swollen joints, if present, would put them in polygonaceae.

| I agree with Wandygirl...that is what must have happened.
But... if I do use a herbicide won't that kill all the perennials growing in that box ? Sigh
Thanks everyone for your help...this is a giant puzzle and seems to be hopeless.
Last Fall I even took a sample to a well known nursery and they could not identify it. |

| In that case not wanting to kill all ..I use gloves first latex then a nice cotton glove ...dip in roundup then touch the leaves of ONLY the unwanted plants. |

| i think if it's as invasive as you say and it's ruining your beds, maybe it's not so important what it is at this point but rather to just get rid of it. just a thought. |
