    That looks an awful lot like Poison Hemlock (Conium maculatum) to me but I'm just going by pictures I have found online. One site says that there is always purple blotching on the stems of Poison Hemlock so you should check for that to hopefully rule it out. Google "Apiaceae weeds" to compare.

    There are many nasty weeds in the carrot family (Apiaceae) and some of the others are quite similar to yours. The scourge in my garden is Bur Chervil (Anthriscus sylvestris) which is at least an edible herb. You definitely need to start a campaign to eradicate this weed, whatever it is. Over several years, I've managed to reduce the number of seedlings my Bur Chervil produces by pulling every one before it goes to seed. It may take a few years but worth the effort. Just in case this is Poison Hemlock, be sure to wear gloves.

    Anthriscus and hemlock can be difficult to tell apart, but usually the unpleasant small when crushed will tell you it's hemlock. It also tends to have very bright green young growth, rounded rather than angular young stems, and the mature stems often have a strong purple-red tint at the base.
