A few online references claim that the Chilean and Argentinian box-leaf azara has vanilla-scented flowers. I think they smell more like chocolate, myself. If I am giving a tour at this time of year, this is one plant that is on the must-visit list. The striking thing about the fragrance is that you don’t have to be close to the plant to enjoy it – the smell of chocolate (or vanilla) can be discerned from 10m away if you are downwind from it. It certainly makes it pleasurable to photograph other plants in its vicinity.
