>>982965>>982967>>982974Poison Hemlock (Conium maculatum) and Queen Anne's Lace (Daucus carota) smell nothing alike when you crush up some leaves. QAL smells like carrots. Those leaves are close, but don't match poison hemlock.
The problem of poisoning comes from people harvesting a shit load of carrot family plants and not testing each one, only to have 1 taproot of poison hemlock mixed in with them. Or, they are completely ignorant.
>>982962>>982965The best cues are root color and leaf odor. The closest parsley to the OP's image is "Hamburg parsley" but the leaves don't match, though their root is big and carrot-like. Parsnips on the other hand have a huge range of leaves from carrot-like to big leaves. QAL has carrot-like leaves only, but the taproot too thick in the OP. Though, I can say that if QAL is cultivated in good garden soil, the taproots will get pretty big.
Thus, it is more than likely a parsnip or QAL. Regardless, the larger one is too old to be eaten. If replanted it will produce a big white flower, that all carrot-family plants produce. Do a pinch-smell test.
