The deep red hibiscus sepals used for foléré are grown specifically around Mayo-Danay in Cameroon's far north — the same dry savanna zone that grows the country's millet and sorghum.
Dried hibiscus (roselle) sepals are steeped in hot water, sweetened, and often flavored with pineapple, ginger or mint, then served ice-cold. Street vendors across Garoua sell it from large coolers as a break from the Sahelian heat.
