You have to see this plant in bloom to believe how stunning it is.  It makes a striking vertical backdrop to any shady area.
 
     In spring tall spikes arise from deep-green foliage and feature tiny flowers that bloom from the bottom up.  
 
     Black Bugbane is a larval host to the Spring Azure butterfly, and it attracts hummingbirds, bees and other pollinators.
 
     Black Bugbane prefers part shade but will grow in sun with enough moisture.
