The flowers emerge from a tall, upright stem. Female flowers are maroon in color.
It has green arrowhead-shaped leaves and red-tinted deeply ridged stems, and it sprouts from an aggressive rhizome. The leaves are edible, imparting a pleasing, tart taste, but should not be eaten in large quantities. The tartness is due to the presence of oxalates which are also responsible for its toxicity.
It favors moist soil, so it thrives in floodplains and near marshes
