Answer: Shamrocks are known as Oxalis. There are a number of species and varieties. The most commonly grown in gardens is Oxalis crassipes, sometimes called pink woods sorrel. A common plant in old gardens, it has become less popular in recent years. Its tendency to spread has hurt its reputation with some gardeners. The standard form has pink flowers, but a white flowered form is available.
