Wood Betony is very showy when in full bloom; because of the unusual flowers and foliage, it has a striking appearance. In the upper photograph, the blooming period is almost over and the plant is in fruit. There are other Pedicularis spp. that this plant resembles, however most of them don't occur in Illinois. An exception is the species Pedicularis lanceolata (Swamp Betony), which differs from Wood Betony by its greater height, leaves with shallower pinnate lobes, and preference for wetland habitats. The flowers of these two plants are very similar. Another common name for this plant is Lousewort, which was based on the mistaken belief that it could repel lice and similar parasites from livestock. Return
