The large pointed leaves of the Cup Plant join its square shaped stems forming cups that catch and store rainwater so birds and butterflies often come for a drink and hummingbirds regularly visit. In the fall, goldfinches descend upon the plants to devour the seeds. Silphium perfoliatum occurs naturally in moist environments but does very well when planted in the garden.
