I went to the Lamberton Conservatory in Rochester, NY yesterday. Well worth the paltry $3 entry fee. Cool plants and also turtles and tortoises and little birds crawling and hopping around underfoot. #LambertonConservatory
Aristolochia gigantea. I feel like the common name could be lung plant, or liver-and-gall-bladder plant, depending on whether you see the little green parts or not.
