Cup Plant, Silphium perfoliatum

Cup plant is a native perennial that is 3-6 feet tall with numerous large, yellow composite flowers. The leaves are joined at stem to form a small cup that holds water that attracts insects and birds. We have several cup plants in the Cherry Creek Pollinator Habitat. It started flowering in early July and is still blooming. This would be a great addition to any pollinator habitat.
