Wolf’s Bane, also known as Aconitum, is a poisonous flower that grows wild as an invasive species. Some varieties have been bred to grow as ornamental flowers. This plant gets its name from the Greeks, who used a tincture of Aconitum on the tips of their arrows while wolf hunting. Ingesting this plant causes stomach upset, tingling, numbness, and eventual paralysis of the heart and lungs. Even picking the flower can cause the toxins to be absorbed through the skin, although not likely in enough quantity to affect the heart. Wolf’s Bane is one of many field and meadow flowers that bees will visit for small quantities of nectar and pollen. It blooms in early spring.
