Oenanthe crocata, commonly known as hemlock water-dropwort or dead man’s fingers, is a perennial herb native to riparian zones, damp meadows, and wet woodlands across Europe, North Africa, and western Asia. It often thrives along riverbanks and ditches where the soil remains moist. This species can reach up to 59 inches in height and is characterized by its hollow, cylindrical stems and pinnate leaves with serrated leaflets. The plant produces small white flowers arranged in umbrella-like clusters, typically blooming from June to August. The roots bear pale yellow tubers that exude a yellowish fluid when cut, which are notorious for their high toxicity.

Hemlock water-dropwort is not commonly cultivated due to its extreme toxicity, as all parts of the plant contain potent poisons that can be lethal if ingested. However, its striking appearance, with lush green foliage and delicate flowers, can be deceptively attractive. In cultivation, it requires consistently moist soil and can tolerate partial shade to full sun. It should never be planted near accessible areas frequented by children or pets.CC BY-SA 4.0
