This is Aristolochia Galeata Nova Odessa. These are very interesting dark brownish maroon blossoms. Having a very hairy pelicans beak, with a large hanging flap, makes this one of the most interesting blossoms I have ever seen. The plant turns its hairs around so that insects can enter the throat, and then the plant turns the hairs the opposite way to trap the insect inside until it climbs around and pollinates the plant. All Aristolochia species, except for the Aristolochia gigantea, are larval host plants for the Pipevine Swallowtail, Polydamas Swallowtail, and Mylotes Cattleheart butterflies. USDA Hardiness Zones 8 to 10.
