Plant hermaphrodites
The diversity of tree flowers lies in more than just their physical appearance – take their multitude of reproductive strategies, for example. A cherry tree has "perfect" (bisexual or hermaphrodite (Refers to a living organism that possesses both male and female organs.)) flowers, with functional stamens and pistils.
However, this is not true of all perfect flowers. Although those of a sugar maple have both stamens and pistils, often only one sex is functional.
