Description

This was observed on the Evergreen campus. Characteristics include a hollow stem. The internodes of the main branches are longer than the stem sheath. The jointed stem is also very noticeable. I found that wherever this plant was growing, it was very abundant.

Description from Wikipedia

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.
