Posted by Bonehead (Planet Earth - Zone 8b) on Nov 27, 2013 11:43 AM concerning plant:

This is a late blooming monkshood, usually one of the last flowers to bloom in my Pacific Northwest garden (October). It is both a tall and strong plant, able to hold itself up without any support. Attracts the last of the hummingbirds.
