Also, in an unusual case, a wet ditch may be right next to a dry disturbed area, putting these two plants within feet of each other. On the other, hand Poison Hemlock, Conium maculatum, is a very different plant than Water Hemlock, Cicuta sp. It grows in the same ecosystems as Daucus, and there is a great chance of mistaking the two. Stem hairy 2. No purple spots on stem, but sometimes purple blotches 3.
White root smells like a carrot.
Purple spots on stem 3. Root smells like urine at best. Please use all three characteristics, not just one of them. The smells of the Hemlocks seem to change depending on environmental and other factors. I have smelled Hemlock seeds that have pleasant fennel-like aromas.
