Pink Shamrock

Pink Shamrock is a particularly interesting and beautiful member of the worldwide Oxalis family, which includes the wood sorrels and clover-leaved plants of all sizes and descriptions. This oxalis is native to Mexico, but has been cultivated in Europe since Victorian times. It is particularly handsome, both in flower and foliage, and has lots of common names. 'Iron Cross Oxalis' is one, and 'The Good Luck Plant' is another. Each of this plant's leaves is a perfect four-leaf clover. What's more, the leaves have distinct 'iron cross' markings in the centers, in fact, some hybrids have a clear maroon splotch on each petal, forming a cross. Pink Shamrock's summer flowers are also edible, often used in salads.

Oxalis tetraphylla, formerly known as Oxalis deppei, is hardy to approximately zone 7, and it makes a great container plant anywhere. Unlike many of its genus, this Oxalis enjoys full sun. It's slow to come up in the spring after winter, and begins blooming in July.'
