These seeds are from Aristolochia coryi. This vine only grows about 3 feet long but it shows off gorgeous little yellow, green, maroon, and burgundy flowers from late Spring until Early Fall. The blossoms attract a large variety of bees, birds, and butterflies. 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 11.
