Poison hemlock (commonly mislabeled carrot-fern) thrives in moist, well-drained soils in full sun to partial shade and requires regular watering during dry spells. This plant is extremely toxic to humans and animals and should never be cultivated in home gardens or near children and pets. It is best left to naturalists and educators in controlled settings only.
