The center of the flower is darker colored, which attracts pollinators along with a distinctive odor to its reproductive elements.

[1] The plant is native to the Caribbean and Central America, and has been introduced to Florida in the United States as an attractor of butterflies.

Aristolochia grandiflora is pollinated by breeding flies attracted by an odor produced by the flower.

Flies travel down the tubular part of the flower to the utricle where the reproductive organs are found.

The entire reproductive process lasts two days before flower senescence and abscission occur in the third phase.
