Oxalis Pes-caprae, also known as Bermuda Buttercup, African Wood-sorrel, or Soursob, is a flowering plant that belongs to the family of Oxalidaceae. Its yellow buttercup-like blooms are a common sight in gardens and along roadsides, and it has become naturalized in many parts of the world. However, its spreading habits and invasive nature have led to its classification as a noxious weed in some areas. Other synonyms for Oxalis Pes-caprae include Cape Sorrel, Lemon Clover, and Sleeping Beauty. While the plant's bright, cheerful flowers are certainly attractive, its ability to wreak havoc on natural ecosystems means it is a cautionary tale for gardeners and conservationists alike.
