These seeds were collected from Aconitum napellus, also known as Aconite, Blue Monkshood, and Monks Coule. This perennial likes to live in sun to partial shade where it can grow to about 4 feet tall. The blue and violet blossoms are on display from the middle of the summer until early fall where it attracts a wide variety of birds, bees, and butterflies. This is a great plant for making cut flowers. USDA Hardiness Zones 2 to 9.
