Habitat

As the common name suggests, Leavenworthia stylosa grows only in cedar glades and adjacent habitat. Cedar glades are sites in the central eastern United States where limestone lies on the surface resulting in an unusual ecosystem. Along with Eastern red cedar, for which the glades are named, Leavenworthia stylosa is one of the characteristic plants.
