Thanks for the warnings about invasiveness.

Adds a nice zing to salads.
Used to treat Sinusitis (inflammation of the sinuses) and cancer.

On a positive note about this plant, it is one of the four ingredients in the Ojibwa tea of life, used as an immune system tonic and potentially a cure for cancer. PlantFiles has it listed that all parts of the plant are poisonous, but so far the only reference to anyone being poisoned by this plant that I have found were some sheep in New Zealand. Apparently, in rare instances a high concentration of nitrates can accumulate in the plant and cause poisoning. Also, a large quantity of oxalates (such as those consumed by sheep on a sorrel binge) can cause calcium deficiency, renal failure and nervous disorders. So as long as you're not a sheep presented with a whole field of sorrel, it doesn't sound like a few cups of Native American tea would do you any real ha... read more

I would not want this in my yard, but it grows in fields around here. I used to gather the blooms & leaves, boil them, then use the strained liquid to make a delicious and beautiful jelly.

Is there a rating worse than negative? This weed has been a nightmare for me for about 3 years now. It has overtaken several flower beds and a good portion of grass. We have pulled and dug so many times and probably put down a million pages of newspaper trying to keep it from coming back. The runner roots go for miles!

These weed is horribly invasive. It grows anywhere, under any conditions.

If you try to remove a plant, it gets cut off below the soil line and you get more plants in place of that one.

This is an indicator of increased soil acidity in lawns (useful as a diagnostic)

A perennial from Europe and can be found in almost all temperate regions across the world.

Has arrow shaped, light-mid green, leaves which often turn red in Autumn. Bears spikes of reddish, tiny flowers.

Flowers May-August.

Loves acid soil and may tolerate neutral soil, well drained and poorish soil are preferred. Likes grassland and loves lawns, where it will march rapidly gaining large portions of territory if not kept in check.

The leaves are used in cooking and leaves can be chewed to quench thirst, it contains quite a few minerals the main one being selenium. It has a bitter taste so don't be too free with its useage. It is used in soups and salads mainly and is more palatable than common sorrel.

It has a... read more
