The Soil Under Rooibos Cannot Tell It Is Farmed
Someone sequenced the soil bacteria under wild rooibos and under a farmed field nearby. No significant difference turned up, which unpicks a tidy sustainability claim.
Rooibos Bushes Keep Turning Up Insects Without Names
Between 2020 and 2022, three leafhoppers new to science were collected on cultivated rooibos and described for the first time: Geelus dundraad, Colistra acapitatus and Colistra bucapitatus. None of the three does the plant any harm.
The Honeybee You See on a Rooibos Flower Is Not Working
Honeybees crowd rooibos flowers every spring, but a decades-old entomology survey found they take the nectar and give nothing back. The actual pollinators are a short, particular list of solitary bees and wasps built to spring the flower's own lock.
Almost Every Cup of Rooibos Comes From One Plant, Picked in the 1930s
Wild rooibos grows across roughly 600,000 hectares of the Cederberg and Bokkeveld as at least four genetically distinct types. Nearly every cultivated bush you have ever steeped descends from just one of them, selected in the 1930s, and the wild relatives that did not make the cut are still out there, mostly untasted.
Rooibos Has Nearly 280 Cousins, and Almost None of Them Became Tea
The genus Aspalathus holds close to 280 species, nearly all found only in the Cape. Three relatives were once brewed as "stekeltee," and the historical record suggests rooibos itself is a surprisingly late arrival to the Cape teapot.
How Wild Rooibos Is Harvested, and Why It Rests Every Other Year
Wild rooibos is not planted, ploughed, or sown in rows. It is cut by hand from the veld on a rule harvesters worked out mostly by watching what killed a bush and what let it come back, later confirmed by a decade of field research.
Rooibos and Honeybush Are Not Cousins, Not Really
Both are caffeine-free, both grow only in the Cape, and both get called "the other South African tea." Past that, they are two different plants from two different tribes of the legume family, two different mountain ranges, and two different antioxidants, and the historical record on how each was actually brewed is stranger than either box on the shelf lets on.
The Red Bush Changes Its Own Soil, Then Changes It Back
Nobody fertilises a rooibos field. The plant grows in famously hungry soil by striking a daily bargain with bacteria that live in its own roots, one it renegotiates every morning and, by the record's own reading, lets lapse every night.
More of the Cederberg Is Under a Conservation Pact Than Under Rooibos
Rooibos farms in the Cederberg have signed more land into formal conservation agreements than the entire industry cultivates, a corridor that also keeps a camera-trapped leopard population, a dying cedar, and the plant's own wild backup moving.
Fynbos
Fynbos is the fine-leaved shrubland that covers South Africa's southwestern Cape, one of the six floral kingdoms of the world and the ground rooibos calls home. What the shrubland is made of, why fire keeps it alive, how rooibos's own trick of soil chemistry fits it for the ground, and the protection and the threats the whole system now lives under.
The Sustainability of Rooibos
Sustainability in rooibos is four subjects rather than one: the fynbos the crop is planted on, the wild plant that still grows unfarmed above it, the certification marks that each promise something different, and the question of who owns the land and who receives the money. This is the canonical account of all four, with the figures each of them rests on.
The Cederberg
The Cederberg, a sandstone mountain range in South Africa's Western Cape, is the home of rooibos and almost its only home. This is the canonical account of the region: its location and boundaries, the acid fynbos soil and winter-rain climate that suit the bush, the legume and fire adaptations that fit it to the place, and the geographical protection that has fixed the name to the ground.
