Passiflora suberosa is a species of passion flower that is native to the Americas. Its range stretches from Florida and the Lower Rio Grande Valley of Texas in the United States south through Mexico, Central America, and the Caribbean to South America. It is commonly known as Corky-stemmed Passion Flower due to the corkiness of older stems. The fruit is not hardy and transitions from green to indigo, purple and, lastly, black as it ripens. This species is a host plant for the caterpillars of the Gulf Fritillary [Agraulis vanillae], Julia Heliconian [Dryas iulia], Mexican Silverspot [Dione moneta] and Zebra Heliconian [Heliconius charithonia].
