Thames Travelling
Horsetail fern grows freely along the River Thames.

Millions of years ago dinosaurs used to feed on it. We know this because the plant contains silica which ground down the dinosaur's teeth.

Horsetail fern

The Horse-Tail fern is one of the oldest plants in Britain today, and one of the most interesting to look at. It's been around since the time of the dinosaurs.

It nearly always prefers to grow near water.

It is now an endangered species in many places where it used to flourish, so watch out for this beautiful dark green plant, with the delicate black bands around the base of each segment, and treat it gently.
