‘The oldest surviving family of plants on Earth is the Equisetum – the horsetail. The fifteen or so species that persist today have known 395 million years of Earth’s history.’  ~  Hope Jahren, Lab Girl: A story of trees, science and love, Fleet, London, 2016.

To my eye, Equisetum has an ancient look to it. The plant was on this planet long before humans and I’m sure it will be around long after humans have passed. Its spears are pushing up everywhere now, a literal sign that Spring has sprung.
