    This plant is a parasite of the oak and sometimes beech trees. Its thick fleshy roots grow on the roots of oaks and it only flowers after about four years, appearing in the spring.
    Looking rather like pale pine cones, the flower stalks are eaten by many mammals, including deer and bears, and the seeds are distributed throughout the forest in the feces of these animals.
    Grows mostly in old hardwood forests and is native to the eastern US.

    achlorophyllous- no chlorophyll
