Repeated mowing of prairie habitat may also threaten earleaf false-foxglove, particularly if haymeadows are mowed before seed set and dispersal. Recovery Needs Haying activities should be limited in areas known to harbor populations of earleaf false-foxglove. At the least, haying should be avoided until plants have set and dispersed seeds. Herbicides use should be avoided in areas where this plant exists. Mature plants are covered with short, stiff hairs.
Stems are four-angled and unbranched to slightly branched.
Leaves are numerous, opposite, and borne directly on the stem. They are lance-shaped and tend to be a purplish green. Venation is pinnate. Inflorescences are unbranched flowering stalks. Small green leaflike bracts occur at the base of each flower.
