Apparently it's not easy being an annual, disturbance-dependent hemiparasite. But such is the life of the earleaf foxglove, a fall-blooming wildflower that formerly occurred in prairie and prairie-like habitat from New Jersey to Minnesota, south to Texas, Mississippi and Alabama. As an annual that completes its life cycle in a single growing season, it requires open places in the vegetation for its seed to germinate - perhaps created in the past by herds of bison or elk, now both gone from the prairie. As a hemiparasite, it depends on root connections with other plants to obtain some of its nutrients. Today this unusual plant is found in only a scattering of sites across its formerly expansive range.
