Country diary: All hail the horsetail, a plant that could survive anything | Kate Blincoe

Newton Flotman, Norfolk: It looks like a toilet brush yet predates the dinosaurs. I can’t help but give it a stroke by the roadside, even if I get strange looks

The rural road is flanked with a bank of green fuzz. It’s jungly and verdant – lush in a landscape that has turned brown and yellow from drought. I run my hand over the green bristles erupting from a bamboo-like stem.

Equisetum arvense, or field horsetail, looks fluffy, but it is wiry and rough. One could serve effectively as a toilet brush. The bristles are rich in abrasive silicon, which gives the texture of sandpaper. This explains another of equisetum’s common names, scouring rush, from when it was used to clean wood and polish metal. If you are careful, a hollow jointed stem can be separated at its junction and then rejoined like children’s tubular pipes for building, slotting back in a satisfying way.
