If you are looking for a spectacular flowering vine then Aristolochia gigantea could be the one, but only if you plant it in the right position.
It needs to be planted where you can see it, but preferably ‘down wind’ as we will explain.
It was fascinating to read an article suggesting that you could use these as cut flowers, we think not, unless you have a very dull sense of smell.
So although this plant which is originally from Costa Rica, Panama and surrounding areas, is a fast growing evergreen vine with fantastic looking flowers, the flowers themselves smell very unpleasant smelling, in fact they stink. They are are a little less offensive than their relative A. grandiflora, and this is still a spectacular plant, just keep your distance.
Aristolochia gigantea also known as Brazilian Dutchman’s Pipe and Giant Pelican Flower. It will grow to 15 – 20′ in height depending on conditions, flowering in late spring to mid summer.
