Harvesting — Picking the Calyces by Hand
The hibiscus traded internationally — Hibiscus sabdariffa, known in Nigeria as zobo — is grown widely across the north, in Kano, Jigawa, Katsina and neighbouring states. It is used around the world in herbal teas, beverages, food colouring and supplements.
The valuable part is not the petals but the calyx: the fleshy, deep-red cup that surrounds the seed pod after the flower fades. Calyces are picked by hand from around October to December, once they are plump and fully coloured.
Picking at the right time gives the deep colour and acidity buyers look for. Calyces left too long become woody and pale.
