Monkshood, also known as Aconitum, is a perennial plant recognized for its striking blue or purple flowers that resemble a monk's hood. It typically grows in temperate regions and thrives in moist, well-drained soil. The plant can reach heights of 3 to 5 feet and blooms from late summer to early fall. Despite its beauty, monkshood is highly toxic. All parts of the plant contain alkaloids that can be harmful if ingested, making it important to handle with care. Due to its toxicity, monkshood is often used in ornamental gardens but should be kept away from pets and children.
