How many shapes can the flowers of mountain plants have?

Some are so small that it is difficult to see them; others have such particular shapes and colors as to necessarily capture the attention.
Finding a common pattern for all these varieties is impossible.
Does the perfect flower exist?
A flower of this type has petals, which we all know, but also sepals, which are less known: they are the kind of leaves that are at the base of the flower. It then has the stamens, which are the male organs of the flower and are made up of filaments on which the pollen matures, and finally the carpels, leaves
modified which represent the female part of the flower, within which there may be one or more pistils.
