Common lousewort
Pedicularis canadensis
Common Lousewort is a hemiparasitic wildflower that requires a host plant — typically grasses or other native plants — to grow successfully, making it a specialist choice for experienced native plant gardeners. Plant it in a partly shaded, woodland-edge setting with consistently moist, well-drained soil. It is best suited for naturalized or restoration plantings rather than traditional garden beds.
