The proliferation of this stuff along the roads and field edges, especially those that get sprayed with weed killer, is astounding. From what I understand, if ingested, it's not good, but just brushing up against won't yield a reaction like ivy, oak, or sumac will. Anyone have any run ins with poison hemlock? Seems unavoidable at this point. It's even showed up on our farm and I've taken to spot killing it with 2-4D.
