Aristolochia pistolochia seems to be cultivated not uncommonly yet never propagated to a larger extent.

Quite a pity this lovely and rather easy-to-cultivate dwarf species is capable of proliferate via seeds only, which can take quite a time before germination occurs.

 

Interestingly I observed on multiple occasions seed batches germinate very irregularly, but as soon as the time's come all the seeds will pop up within a single day or two. It seems the embryos share kind of an internal clock ...
