Aconitum napellus (Monkshood)
More than just a little splash of color for your late summer/fall perennial or woodland garden, Aconitum, or Monkshood, stands anywhere from three to six feet tall with beautiful dark green, deeply lobed leaves and violet/blue hooded flowers. Monkshood is perfect for the back of the border and also for naturalizing at the edge of a woodland garden. This native perennial wildflower does best with a little shade and cool, fertile soil. Most varieties of Aconitum are extremely poisonous so handle with care. That being said, I have had this in my garden for many years with no ill effects to my cats or dogs. Also, I routinely handle the leaves, roots, seeds, and blooms without gloves and have had no adverse reaction, but that's just me. Zones 4-8. Quarts.
