Shamrock

A shamrock is a type of clover, used as a symbol of Ireland. The word shamrock comes from Irishseamróg (), which is the diminutive of the Irish word seamair and simply means "young clover".

At most times, Shamrock refers to either the species Trifolium dubium (lesser/yellow clover, Irish: seamair bhuí) or Trifolium repens (white clover, Irish: seamair bhán). However, other three-leaved plants—such as Medicago lupulina, Trifolium pratense, and Oxalis acetosella—are sometimes called shamrocks. The shamrock was traditionally used for its medicinal properties, and was a popular motif in Victorian times.
