About

Delphinium is a genus of about 300 species of annual and perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus.

How this plant poisons

All parts of these plants are considered toxic to humans, especially the younger parts, causing severe digestive discomfort if ingested, and skin irritation. Larkspur, especially tall larkspur, is a significant cause of cattle poisoning on rangelands in the western United States. Larkspur is more common in high-elevation areas, and many ranchers delay moving cattle onto such ranges until late summer when the toxicity of the plants is reduced. Death is through cardiotoxic and neuromuscular blocking effects, and can occur within a few hours of ingestion. All parts of the plant contain various diterpenoid alkaloids, typified by methyllycaconitine, and are very poisonous.
