Multipetalous

Multipetalous is a botanical term used to describe a flower that possesses more than the typical number of petals, especially when that number is significantly greater than the species' usual count or is not fixed. In many plant families, such as the Rosaceae (roses, poppies) or Ranunculaceae (buttercups), flowers naturally have a high number of petals, and these are considered multipetalous by definition. However, the term is also often applied to cultivated varieties or cultivars where a genetic mutation or selective breeding has resulted in a doubling or tripling of the petal count compared to the wild type. This phenomenon is known as petalody, where sepals or stamens are converted into petals. For instance, a standard rose might have five petals, but a cultivar like a 'Rosa chinensis plena' can have dozens. While some flowers are naturally multipetalous, meaning their wild ancestors and species typically exhibit this trait, in other cases, it is a cultivated characteristic. The increased petal count can affect the flower's appearance, making it more showy or elaborate, and can sometimes impact its reproductive capacity, as the modified stamens may no longer produce viable pollen or the nectaries might be altered.
