  1. The plant · In 1911 a botanist presented the rooibos shrub as a new species In a paper read in May 1911, Rudolf Marloth described the rooibos shrub as a new species, Borbonia pinifolia, though Nicolaas Burman had named the plant in 1768.
  2. The plant · 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.
  3. The plant · 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.
  4. The plant · The Molecule It Took Chemists Forty-Four Years to Copy Aspalathin was identified in 1965. Chemists did not manage to build it from scratch in a lab until 2010, and the reason is written into the molecule's own shape. Here is what makes rooibos's signature compound so awkward to fake, and why anyone bothered trying.
  5. The plant · Why Rooibos Has Been So Hard to Sequence, and Why the Ministry Wants It Done Rooibos carries a genome roughly a billion base pairs long, packed with the same tannin-like compounds that make its tea, and those compounds fight every attempt to read its DNA. Here is what scientists have found so far, and why a finished genome matters for a crop already running short on stress tolerance.
  6. The plant · 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.
  7. The plant · 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.
  8. The plant · 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.
  9. The plant The plant · Rooibos Gave Its Name to the Fungus Trying to Kill It A fungus has been killing rooibos bushes in the Cederberg for decades, and when scientists finally sorted out what it was, they found it was already infamous, on another continent, under a soybean farmer's name for it.
  10. The plant · The Rooibos You Buy Has Its Own Variety Name Nearly every rooibos field grown today is one narrow, bred selection, not just "the red bush." Growers and chemists call it the Nortier type, the Rocklands type, or in Afrikaans mak tee, tame tea, and the identity runs deep enough that a whole botanical group carries its breeder's name.
  11. The plant · Rooibos Waited Ninety Years for a Second Variety Nearly every rooibos field alive today still runs on one man's 1930s selection. Only in the last few years has anyone seriously tried to breed a second one, and the person doing it is the same botanist who spent the 1990s taming rooibos's sister crop, honeybush.
