This plant grows wild in wet areas. It has a huge tap root. In the winter it has a 2 to 3 feet tall reddish brown stalk. I think it is a good medicinal plant but can't remember why I think that!
The leaves resemble horseradish but I can't get a good idea of the size of the plant. And the brown winter stalk doesn't fit. But perhaps wild horseradish. It is sometimes used as a medicinal plant.
Well I think I am going with Rumex crispus. It looks similiar to the photos of Rumex hymenosepalus but this thing grows where it is wet usually. So...is it just a weed, or does it have some beneficial properties? Thanks everyone!
