Cup plant
Silphium perfoliatum. Prefers medium to medium-wet soil and full to partial sun. Grows 6 ft tall and spreads vigorously to create large dense patches, which attract birds to drink from water that collects in the leaf cup and to feed on seeds in the fall. Grows well in average soil as well as wetter, heavy soil. Blooms midsummer to early fall.
