One of my favorite vines... actually, all vines are my favorites ;-)
The flowers of Aristolochia gigantea are simply amazing, deep red and cream with a bright yellow center.
Large ovals looking like marbled steak meat, but no, they do not attract flies nor do the flowers have a bad fragrance.
The leaves are perfectly heart-shaped and with the pendulous flowers the runners sure looks like a summer garland
The back of the flower is just as interesting
the common name is Dutchman's pipe, I guess the flower bud resembles a pipe?
The seed pods are little hanging baskets, filled with seeds
This variety serves as host plant for the Polydamas Swallowtail (or Gold-Rim Swallowtail). I read it is poisonous to the Pipevine Swallowtail. I never saw a Pipevine Swallowtail on my plant but it supports hundreds of Gold Rims each year.

The, oh so alien looking, pupa

They don't hold still making it hard for me to get a good picture :-/
