“A Group (previously cultivar-group) is a formal category in the International Code of Nomenclature for Cultivated Plants (ICNCP) used for cultivated plants (cultivars) that share a defined characteristic. It is represented in a botanical name by the symbol Group or Gp. Group or Gp is always written with a capital G in a botanical name, or epithet. The Group is not italicized in a plant's name.” [Ref]
