Field Horsetail

Description:

Equisetum arvense, the Field Horsetail or Common Horsetail, is a herbaceous perennial plant, native throughout the arctic and temperate regions of the northern hemisphere. It has separate sterile non-reproductive and fertile spore-bearing stems, growing from a perennial underground rhizomatous stem system. The fertile stems are produced in early spring and are non-photosynthetic, while the green sterile stems start to grow after the fertile stems have wilted, and persist through the summer until the first autumn frosts.

Habitat:

Between the Grass in the Dunes of Terschelling.
