What is "soleirolia"

Soleirolia soleirolii (, syn. Helxine soleirolii) is a plant in the nettle family. It has a number of common names, including baby's tears, angel's tears, mind-your-own-business, peace-in-the-home, pollyanna vine, polly prim, mother of thousands, and the Corsican curse. It has also been called Irish moss; however, it is not a moss, nor should it be confused with Sagina subulata or Chondrus crispus (an alga), which are also known as "Irish moss".
