Moist, rich, heavy soils of roadsides, meadows, fields, disturbed or waste areas, shorelines, and forest edges.

Parts Used:
Young leaves, seeds, roots

Wild Food Uses:
The high amounts of oxalic acid gives the young leaves a pleasant sour flavor. I love to eat them raw, as well as add them to salads. The plant is very high in vitamins A & C, protein, iron, thiamin, riboflavin, and potassium. As the plant matures, the leaves become much too bitter to be palatable. The young leaves can also be used as a potherb. The seeds can be gathered and used as you would other members of the buckwheat family. It can be boiled and eaten as a porridge of sorts. It can also be ground and used as a buckwheat flour.

I have heard anecdotal evidence that because of certain compounds, eating too many leaves can increase ones risk of kidney stones. Some people have also been known to have slight gastric upset from eating this plant. As with all wild foods, if you eat them in moderation you should be able to forestall any undesirable effects.
