Giant hogweed was confirmed in DuPage county last week. The second infestation to be identified in Illinois is found at the Morton Arboretum.

No seeds have been released from the plants in recent years.

My son was exposed to Hogsweed In Channahon Illinois in Will County this week. He was weed whacking and the sap sprayed on his forearms. He developed the blisters shown in the photos. These plants were of a smaller size than the giant Hogweed photos we observed and the flower part was a yellow in color. Not White. The leaves and flowers were identical to the photos in every other way. We stopped cutting the plants after his injuries were sustained. We would like to contact someone who can positively identify the plants and give us a suggestion or help us in there safe removal.
