Lemon Beebalm (Monarda citriodora)

''Monarda citriodora'' is a species of flowering plant in the mint family, Lamiaceae, that is native to much of the United States and Mexico. When crushed, the leaves emit an odor reminiscent of lemons. This odor is sometimes described as more resembling oregano, especially late in the season. Its purple flowers are highly attractive to butterflies, bees and hummingbirds.
