Yellow Wood Sorrel, Sour Grass
Oxalis stricta / Wood Sorrel Family

This is a common yard weed. I photographed this plant in my yard. This is not related to grass, the "sour grass" name comes from the taste of the leaves. Don't sample too many of them though, they contain oxalic acid which can adversely affect the kidneys.
Perennial
Where seen:Oak Ridge, Great Smoky Mountains NP, Warriors' Path SP, widespread
{Formerly known as: Oxalis dillenii}
