    This is a nice monkshood that can stand on its own without any staking. Easy to divide in the spring when it is emerging. In my PNW Zone 8 garden, it grows to about 6' tall in a morning sun/afternoon shade location. Not bothered by bugs or disease. Spreads out to a clump about 1' round. It blooms earlier than the late fall varieties and can be comingled for a lasting show.
