Did you know you can find living fossils in the Tillamook State Forest?
Horsetails (Equisetum spp.) first appeared in the early Jurassic, more than 100 million years ago! While Stegosaurus and Hadrosaurs might have munched on these ancient plants, you should only eat them when they’re young. The young shoots are often eaten like asparagus but as the horsetails grow, they absorb silica from the soil making the plant incredibly abrasive. So much so it’s also called a scouring brush and is a great tool for scrubbing dishes.
Have you ever tried using this ancient plant as a snack or scrubbing tool?
