Wood Sorrel (Oxalis stricta). Known also as: Sourgrass, Common Yellow Woodsorrel, Yellow Woodsorrel, Common Yellow Oxalis, Lemon Clover, Upright Yellow-Sorrel.

This is one of many plants that has higher than average levels of oxalic acid, please see note here.

Since it is higher than average in Oxalic acid, I suggest not eating it raw, but if you do, keep the quantity very low. By the way, some people really dislike the taste of it. I find it tart and pleasant in very small quantities. Cooked is the way to go, and I also suggest using it as a spice in foods, not as a vegetable. The tartness will add some zing to foods, and the small amounts will not be harmful to the average person.

Growing this plant in your home garden:

I don't know, but I can't see why this would not establish at home if you have the right conditions - see "Habitat" below. Seeds gathered raked into top of soil should do the trick.
