Although one of the more widespread species in culture most plants cultivated and sold under the name of Aristolochia gigantea in fact are hybrids of A. gigantea x elegans.

 

Aristolochia gigantea s.str. is a truly outstanding species with massive flowers reaching up to 50 x 25 cm, more than double the size of the hybrid specimens. Another quite distinguishing feature is its scent: It smells not disgusting as most other species do but rather like cleansing agent with a breeze of citrus. 

 

Mature plants require much space and are capable of covering a complete patio within a few weeks. Luckily this rewarding climber can be cut back easily and will be very happy if supplied with lots of fertilizer and water simply.
