Often regarded as the world's most expensive spice, saffron is now being grown in the Waitaki Valley.
Kurow Saffron is a venture run by sisters Sarah Hines and Joanna Towler, who planted their first bulbs in January 2017.
The bulbs multiply over time, and this year had been more than twice as productive as last year, Hines said.
Saffron comes from the threads of the flower of Crocus sativus
It is a labour-intensive process, as about 100 flowers are needed to produce 1g of the spice.
