Aconitum napellus (monkshood), I read, the feeling of sickness growing inside me with every line. One of the most toxic flowers native to the UK. Aconitine is a potent heart and nerve toxin, and any part of the plant, including stems, leaves, petals, or roots, can be deadly. Most deaths result from ingesting A. napellus, but gardeners are advised to use extreme caution in handling cuttings, as even skin contact can cause symptoms.
