Flowers differ in the accessory structures they bear in relation to the reproductive organs. The entire purpose of a flower is to ensure reproduction, fertilizing the egg by the pollen and producing a fruit that bears seed.

Some flowers separate the production of pollen from the production of the egg. This means the flowers will be classified by what parts they have or lack.
Complete flowers contain the four regular parts: calyx, corolla, stamens and pistil(s).
Calyx is the ring of sepals usually green on the outermost portion of the flower.
Corolla includes the inner petals that protect the reproductive organs.
Stamens are the male reproductive organs.
Pistils are the female reproductive organs including the ovary.

Incomplete lack one or more part.
Perfect flowers have both pistils & stamens but lack petals or sepals.
Imperfect lack either pistils or stamens and may lack petals or sepals .
Naked flowers lack petals (apetalous) or sepals (asepalous).

Some plants bear two kinds of imperfect flowers, male staminate & female pistillate, so are called monoecious.
Other dioecious plants bear separate complementary imperfect flowers. This is common in hollies that are either female pistillate on one plant so produce berries or staminate and produce no berries.

Petals can be flat or tubular. Tube forms vary by being urn-shaped like lily-of-the-valley or flaring like morning glories.

The calyx & corolla can join at the base of the ovary-hypogynous, or at its top-epigynous. They can join at its outer edge and cup it, perigynous.

This is only a small part of the ways to key flower structures because so many are irregular or not radially symmetric.
Some bloom at night to attract night flying pollinators. These usually lack much color but are intensely fragrant. Day blossoms often have nectar guides, some in the UV spectrum.
This site shows the flowers both as we see it and as an insect might.

Flowers have adapted to attract pollinators and some hold the organism to ensure pollen attachment.

Some plants even time their flowers enmass. Plants that flower this way are referred to as mast flowering or gregarious flowering. These plants take several years to gather resources to flower in synchrony over a large area then some die once they have set seed. Oak trees, bamboos and Strobilanthes are known for gregarious flowering.
Next come all the ways to classify fruit such as the fleshy versus the dry fruit: plums, brries, nuts, grains, achenes, samaras.
