A mint family member, Obedient Plant looks best in an area where it has room to spread.   When in bloom, a field of lavender blooms, pulling in hummingbirds, native bees and other pollinators sways in the breeze.  I have a bunch of Obedient Plant in my garden, and that's the plant people stop and ask about.
 
     Fun fact: Obedient Plant got its name because when you push a bloom from one side of the stem to the other it stays where you moved it. That's obedient!
