Like its larger cousin Aristolochia hirta, A. guichardii belongs to the SE Mediterranean hirta-clade characterized by saxophone-shaped flowers laced with smaller and larger, hairy trichomes all over the shoots and flowers.

The first ones to pop open will lie right on top of the soil and emit a strange odour to attract pollinators.
