obedient

As I walked through Jenkins Arboretum this morning I saw a sign sitting in the middle of some flowers wearing pink petals stating that the name they wear is "obedient plant". Apparently the reasoning behind the name is because a flower pushed to one side will often stay in that position. Most of them were standing tall but I did see a few with stems bent parallel to the ground with a reach for the sky occurring near the end of the stem.
