Water Hemlock (Cicuta maculata L.)


Conditions of poisoning

Water hemlock is among the most poisonous plants in Illinois. Although the leaves and fruit, either green or dried in hay, can be eaten without danger, a relatively small amount of the tuber will kill a cow in a short time. There is little danger during summer and fall as stock are not likely to browse on the tall coarse plants. But in early spring they will eat the young leaves and stems sprouting from the ground, and in doing so may pull the shallow tubers out of the soft wet ground and eat them also.
