This truly amazing species is one of the most admirable of all Aristolochia for sure.

Native to Oaxaca and Chiapas in Mexico it entered cultivation only once almost a century ago.

It was feared it had gone extinct in the wild during the 19th century until investigations in the highland rainforests of Mexico revealed a few more specimens. Little is known about its ecology since it is so poorly studied and rare.


Fortunately Aristolochia tricaudata is an easy yet slow-growing species in cultivation. As artificial pollination never succeeded to my knowledge the propagation via cuttings is the only reliable method.

The problem with these is they require an extraordinary long time to form callus and frequently die off before developing roots  (applying to most tropical Siphisia species)
