Synonym for the grape variety Petit Verdot; see there.
This red grape variety comes from France. The name "Little Greenling" refers to the high acidity in the grapes, which are often underripe due to the long ripening period. Synonyms are Bouton, Bouton (Bonton) Blanc, Carmelin, Heran, Herrant, Lambrusquet, Lambrusquet Noir, Petit Verdau, Petit Verdot Nero, Petit Verdot Noir, Plant des Palus, Verdau, Verdot and Verdot Petit. It must not be confused with the Fer (Herrant) varieties or with Gros Verd ot, which was mentioned together in 1736, despite seemingly suggestive synonyms or morphological similarities. The exact parentage of the Petit Verdot variety is unknown; according to DNA analyses, it seems to be descended from wild vines near the Pyrenees.
