Plants of the genus
Delphinium contain toxins, and no parts of them should ever be eaten. They can be fatally poisonous to both humans and animals. Sensitivity to a toxin varies with a personís age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plantís different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil. Conspicuous Flowers:
