Comments: Monkshood bears hooded, blue flowers (Vis. 1) in

needs well-drained, moist soil and partial shade. The
plant grows best in cool weather and is not harmed by
light frosts in the fall. Monkshood does not like to be
disturbed.

absolutely need it. Starting seed may not be reliable.
The seed needs moist storage at 41 degrees for six weeks
to overcome dormancy.
