Aristolochia fimbriata Cham.


Fimbriate Birthwort


perennial, scrambling geophyte < 2 m, tuberous taproot


2-3 cm, odour barely noticeable


Brazil, Bolivia, Argentina


thick-shelled, triangular to ovate, small elaiosome

This tropical highland species surely belongs to the most admirable Aristolochia.

The curiously tentaculated flowers appear in every leaf axil along the shoots while a mature plant can produce more than 300 of these in one season!


Unlike many other species from the same origin A. fimbriata is a self-pollinating species producing masses of seeds each year.

Anyway it does not display a weedy habit as it draws back completely to the tuberous underground stem in winter.
