Malvidin is an O-methylated anthocyanidin. As a primary plant pigment, its glycosides are highly abundant in nature. It is responsible for the blue color found in petals of the Primula plants of the polyanthus group. Blue flowers of the blue pimpernel (Anagallis monelli) have also a higher concentration of malvidin. Malvidin is responsible primarily for the color of red wine, Vitis vinifera being one of its sources. It is also present in other berries, such as the chokeberries, or the saskatoon berries (Amelanchier alnifolia).
