Question
Here's one at the upper reaches of the tidal zone at Joppa Flats, Newburyport. Also found at Deer Island in the same zone. Rivals cattails in height. Stem to the touch seems octagonal. Reminds me of the mint family and some Rumex.
Answer
Dear Chaffee, your plant is Amaranthus cannabinus (salt marsh water-hemp). It is usually found on brackish river shores and similar locations (rarely found on inland waterways). Best wishes.
