This Brazilian native vaguely resembles the Sherlock-style pipe that was popular in Holland, despite being located halfway around the globe. Also known as the Giant Pelican Plant, the flower gives off a foul odour despite its spectacular appearance. But that’s not the only thing that makes the Giant Dutchman’s Pipe less than appealing. The plant is classified as a danger to the Pipevine Swallowtail butterfly, which confuses the Dutchman’s Pipe with its native host plant. The Dutchman’s Pipe, though similar to the host plant in appearance, does not support the Pipevine Swallowtail butterflies’ eggs and will only kill the caterpillars.
