It leaves are long and pointy and they body of it has nodes.
Found this in Madrona park!!!
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.
Hollow stocks with 10 to 12 nodes. Hair-like branches come off of each node all around the stalk. Likes a variety of soils, and spreads easily.
jointed stems, branched, hollow, 10-12 ridged sheaths, green 10-12 brownish teeth
moist to wet forests, meadows, swamps, along roadsides,
around Evergreen campus walkways
Found by the longhouse growing next to a population of sword ferns. 9 individual stems bunched together. Slighty hunched over and low to the ground. Not standing upright like normally. Hollow like a straw with black bands wrapped in patterns around the stem.
LOTS of horsetail growing under willow/kanuka/alder canopy. Well established.
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.
