The indigo dye in Hong Kong is rarely made from local seeds. Thus, The Mills reached out to a local agricultural education group Kids Club to explore the possibility of creating a “Hong Kong Blue” for our “Colours of the Earth” programme last year. We wanted to see whether a seed can adopt the locale’s climate, environment and soil to flourish into a plant unique to that plot. Kids Club’s farmers compared our indigofera tinctoria seeds from India with local ones and made adjustments according to their development – or lack thereof. What resulted was the impressive cultivation of indigofera tinctoria that makes “Hong Kong Blue” a reality.
