Aristolochia watsonii seems to constitute the northernmost representative of the odd Mexican subsection Pentandrae as its distribution are extends as far as to the southern US.

 

The very narrow, arrow-shaped and reddish coloured foliage is just one reason why this amazing little oddity definintely should become more common in cultivation.
