Although rooibos has been consumed for centuries, it has only been grown in recent times. In the mid-19th century, a German priest from Namibia founded the village of Wupperthal in South Africa. He imposed strict rules on the community and set about organising the cultivation of rooibos. Halfway between the Cape and Namibia, Wupperthal is in the middle of the desert. Rooibos, or Aspalathus lineari, is about as undemanding as a camel, and can withstand extreme heat without complaint. The plant’s roots push deep into the ground, which helps it find nourishment. Wupperthal is worth a visit. It’s a journey of several hours along a difficult track, which nonetheless offers some beautiful views for those who like their landscapes arid.
