Petals can differ dramatically in different species. The number of petals in a flower may hold clues to a plant's classification. For example, flowers on eudicots (the largest group of dicots) most frequently have four or five petals while flowers on monocots have three or six petals, although there are many exceptions to this rule.

Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower. Petals attract pollinators, and reproductive organs that produce gametophytes, which in flowering plants produce gametes. The male gametophytes, which produce sperm, are enclosed within pollen grains produced in the anthers.
The corolla is gametopetalous, the five petals may be joined forming a tube with 4 or 5 lobes (in the flower called tubulose flower or floret, or two groups of petals joined (in the case of bilabiated flowers, with an upper lip formed by 2 petals and a lower lip formed by 3 petals), or they can present a short tube and the limb prolonged ...
A double-flowered cultivar of Impatiens walleriana. "Double-flowered" describes varieties of flowers with extra petals, often containing flowers within flowers. [1] [2] The double-flowered trait is often noted alongside the scientific name with the abbreviation fl. pl. (flore pleno, a Latin ablative form meaning "with full flower"). [3]
The seed production of flower lotus is typically poor regarding yield and quality. Flower types differ in the number of petals (single petals, double petals, or multi-petals) and their colours range from single colour in white, yellow, pink, and red to bi-colour, most often of white petals with pink tips or highlights.

Floral diagram of Anagallis arvensis. [1]: 307 The dot represents the main axis, green structure below is the subtending bract.Calyx (green arcs) consists of five free sepals; corolla (red arcs) consists of five fused petals.
A Lilium flower showing the six tepals: the outer three are sepals and the inner three are petals. Undifferentiated tepals are believed to be the ancestral condition in flowering plants . For example, Amborella , which is thought to have separated earliest in the evolution of flowering plants, [ 4 ] has flowers with undifferentiated tepals.
Aquilegia (common names: granny's bonnet, [2] columbine) is a genus of about 130 species [1] of perennial plants that are found in meadows, woodlands, and at higher elevations throughout the Northern Hemisphere, known for the spurred petals [3] of their flowers.
