Monkshood (Aconitum Napellus) - Monkshood is a beautiful perennial flower with deeply cut foliage and loose spikes of dark violet-blue flowers. It establishes from Monkshood seeds and prefers damp areas with rich humus soil and persistent moistness. The Monkshood plant reaches a height of 36 - 48 inches, and it generally is sturdy enough to not need staking.
This beautiful flower is actually an herb that has been used for centuries. It is useful for the practitioner of homeopathic medicines. This herb can be found in the northeastern United States, the United Kingdom and parts of Europe. The origins of the herb are not known, but many people believe that it originated from Asia. Common names for Aconitum Napellus are Monkshood as the blooms resemble a hood, Aconite, or Wolfsbane as the plant was used to poison wolves. Aconitum Napellus, or Aconite, is poisonous especially the roots. The Aconite plant should never be grown with other herbs you intend to consume. After pruning the plant, thoroughly wash your hands.
Monkshood seeds can be directly sown outdoors in late fall or early winter for germination the following spring.

After the cold treatment, sow the Monkshood flower seeds in starter trays, and transplant seedlings into the garden when temperatures are warm.
