Oxalis Tetraphylla is a bulbous plant from Mexico. A common name is "Iron Cross", after a famous cultivar; it is also known as "lucky clover", and in a wild or feral state as four-leaf sorrel or, least ambiguously, four-leaved pink-sorrel.
It has leaves divided into four and has been called "lucky leaf" and even "four-leaf clover", but it is not a true clover. Related to the common wood-sorrel (Oxalis Acetosella), it is commonly used as an ornamental plant. It is also edible, the flowers and leaves having a sharp lemon flavor. However, since the oxalic acid in the plant can interfere with the absorption of certain nutrients in the body, especially calcium, too much can be harmful.
This specimen was photographed in my own back garden, it makes an excellent rockery plant situated between light coloured rocks.
