Aristolochia odoratissima - hence its name - is an extremely showy and fragrant species, however, considered enormously lazy-flowering.


By accident I recognized there are to be distinguished several very different strains, considering not only the vegetative appearance but especially the amount of flowers generated.


Even specimens grown from a single seed pod can vary enormously.

Some produce runners over and over, covering whole patios but never flowering in a decade while other (usually more delicate) specimens will produce a raceme of flowers in every mature leaf axil.

I wonder what the use of this mechanism (?) could be in situ...
