Oxalis tetraphylla (often traded under its synonym O. deppei) is a bulbous herbaceous perennial plant from Mexico. It is sometimes sold as lucky clover or shamrock (though it is neither a clover nor a shamrock). In the wild or feral state it is often called four-leaved wood-sorrel after its family, Oxalidaceae. Other English common names for this plant include Lucky Clover, Four-Leaf Sorrel, Four-Leaf Pink-Sorrel and others. It is sometimes called "the iron cross plant" or "oxalis iron cross" because the leaves loosely resemble the iron cross symbol, though this name is not a classic folk term and has fallen out of favour due to the bad political connotations associated with this symbol.
