Scientific Name: Hedychium coronarium
Commonly known as Ginger Lily. First came across this when I first moved to Hongkong. They are intricately meshed with my HK summer days. Every weekend, I would travel all the way to a little village in New Territory from Happy Valley, via bus, then train and finally minibus, then walk through the fields of ginger lily to this tiny farm house where my pottery teacher lived.
Shanghai Tang uses ginger lily as their signature aroma.
