    Petty Spurge (Euphorbia peplus) is my guess, if the stem oozes white sap then it is, also called Milkweed and the sap can be an irritant. It is very invasive and yours looks about ready to shed some seed so get rid quick :)

        It affects some people worse than others. If I lift an armful of weeds with them in to a compost heap, shortly afterwards I'll have wet, red, sore spots all over the skin on the inside of my arms that'll last for weeks.

          I found it reacts with sunlight to cause burns.
          Not sure its a problem without exposure to sunlight.

            So not likely to be a problem to those gardeners who do their weeding at night and subsequently don't go out during the daytime.

              I think the issue is the sap destroys Melanin our natural protection from the sun. Once destroyed the sun can do it’s worst, ie it is not the sap that burns but allows the sun to burn. I am no expert so happy to be told l’m wrong:)

                You can send it to me! I tried to start milkweed from seed several times and failed. It attracts our monarch butterflies :)

                  That's a different milkweed @CanadianLori, the plant the Monarch butterfly eats is in the Ascepias family. The weed identified in this thread is in the Euphorbia family. Both share the same common milkweed name :rolleyespink:
