prêle

Prêle is a genus of herbaceous plants in the division Equisetophyta. These plants are commonly known as horsetails. Prêle are ancient plants, with fossils dating back to the Devonian period, over 300 million years ago. They are characterized by their jointed, hollow stems and whorls of small, scale-like leaves. Prêle reproduce via spores produced in cone-like structures called strobili.

There are approximately 15 species of prêle found worldwide, with a preference for damp, sandy soils. Some species are considered weeds due to their invasive nature. Historically, prêle have been used in traditional medicine for a variety of ailments, owing to their high silica content. Certain species are also used in crafts and as a source of natural dye. While some species are edible, others can be toxic, and identification by an expert is crucial before consumption. The distinctive appearance of prêle makes them easily recognizable in their natural habitats.
