Lilies are one of the most beloved flowers, prized for their elegant, trumpet-shaped blooms and sweet fragrance. But take a close look at a lily flower and you may notice something strange – the number of “petals” doesn’t seem to add up! So how many petals does a lily actually have? Let’s demystify the surprising truth about lily petal anatomy.
The Perplexing Petal Structure of Lilies
At first glance, lily flowers appear to have six petals The blossoms are radially symmetrical, with six flower parts of equal size arrayed in a circle surrounding the stamens and pistil.
However, botanically speaking, not all six of these flower parts are technically classified as “petals.” True lily flowers have just three petals along with three sepals that look nearly identical.
Petals are the colorful showy parts of a flower that attract pollinators. Sepals are leaf-like structures that protect the flower bud before it opens. In many flowers petals and sepals differ in color shape or texture. But in lilies, the sepals and petals are fused into tepals that resemble each other, creating the illusion of six petals.
To summarize
- Lily flowers have 3 true petals
- They have 3 sepals fused into petal-like tepals
- There are 6 petal-like tepals in total
This unusual sepal and petal arrangement explains why lilies may seem to have more or fewer petals than you’d expect!
The Distinctive Trumpet Shape of Lily Tepals
The six tepals of lily flowers have a trumpet-like shape. The tepals attach at the base of the flower’s ovaries in a whorl. From there, they flare outwards into a funnel or bell contour before curving back in at the tips. This graceful, recurved form is characteristic of true lilies in the Lilium genus.
The curving tepals surround the reproductive structures at the flower’s center – the stamens (male) and pistil (female). The tepal margins unfurl just enough to allow pollinating insects like bees to access the nectar inside.
The recurved tepal shape maximizes visual impact by creating a showy floral canopy. The tepals also display speckles, blotches and contrasting edges to further attract pollinators.
Why Lilies Have 3 Petals and 3 Sepals
Most flowers have either three or four petals and sepals, owing to how they develop and genetic limitations. Lily flowers contain three sepals and three petals for a symmetrical six-tepal arrangement for these reasons:
-
Floral organs emerge in whorls from a central stem axis. Lilies have two whorls – an outer sepal whorl and an inner petal whorl.
-
Each whorl contains three members, as guided by genetics. Lilies consistently have three sepals and three petals.
-
Symmetry creates visual appeal to attract pollinators from all sides. The six tepals are evenly spaced in a circle for access.
-
As monocots, lilies have flower parts in multiples of three. Most monocots have petals and sepals in threes.
In short, the lily’s six-tepaled trumpet form satisfies biology, genetics, function and aesthetics!
Variations Among Lily Species and Cultivars
While most lilies follow the three sepal, three petal formula, some interesting exceptions exist:
-
Certain species have up to 10 tepals, like the decatepal lily Lilium formosanum.
-
A few species violate symmetry with four tepals, such as Lilium henryi.
-
Double-flowered cultivars have extra petals bred into the blooms.
-
Albino lilies lack pigment so tepals appear white inside and out.
-
Dark nectar guide lines often mark tepals to point insects to nectar.
So while six tepals is the norm, lilies do display some neat variations. Breeders continue creating exciting new tepal forms!
The Role of Lily Tepals
Lily tepals serve key functions:
-
Attract pollinators with bright colors, patterns and fragrance.
-
Protect ovary by enclosing it before bloom.
-
Support reproductive parts by providing a sturdy frame.
-
Enhance visibility by reflecting light.
-
Repel water with thick, waxy surfaces to keep pollen dry.
-
Reorient toward light to maximize sun exposure.
-
Provide a landing platform for insects to enter the flower.
The ingenious tepal structure allows lilies to thrive through successful reproduction. No wonder they are so widespread and beloved!
Demystifying Lily Petal Counts
Many who admire lilies have pondered their unusual petal numbers. In truth, lilies have three petals and three nearly identical sepals for six total petal-like tepals. This arrangement satisfies biology, genetics, function and beauty in one efficient yet gorgeous package. Although lily petal counting may seem perplexing at first, their novel floral structure demonstrates nature’s creativity. Next time you see elegant lilies, take a moment to appreciate the hidden complexity within each blossom!

How many petals does a lily have?
Liliaceae: Lily Family. Identify plants and flowers. Most showy monocot flowers with parts in threes belong to the Lily family or one of its allies. Lilies have 3 sepals and 3 petals, which are identical in size and color (often referred to as 6 tepals). There are 6 stamens, but some species lack anthers on some of the stamens.
How many petals and sepals does a lily have?
True lily flowers have three petals and three sepals that look nearly identical. Petals are the showy colorful parts of the flower that attract pollinators. Sepals are leaf-like structures that protect the flower bud before it opens. In many flowers like roses, petals and sepals are distinctly different in color, shape or texture.
Do lilies have petals?
But, when it comes to lilies, the sepals are the same color and texture as the inside petals. When the bud opens, it is nearly impossible to tell which are the petals and which are sepals. Petals are typically colorful, fragrant and may produce nectar. The purpose of petals is to attract pollinators to the flower.
How many petals does an Easter Lily have?
Traditionally, flowers grown in flower beds are grown for their colorful petals, which often form a cluster that we refer to as a bloom or blossom. In the case of the lily, what we call the bloom is actually three petals and three sepals. Move your Easter lily plant to your garden after it blooms.
Do lilies have sepals?
Sepals are leaf-like structures that protect the flower bud before it opens. In many flowers like roses, petals and sepals are distinctly different in color, shape or texture. But in lilies the sepals and petals are fused together into tepals that resemble each other, creating the illusion of six petals.
Are all lily flowers symmetrical?
All lily flowers are symmetrical, but the petals come in different shapes, including trumpets, funnels, cups, bells, bowls and flat shapes. Petals also differ within the same hybrid division, such as the Asiatic hybrids that have flowers that are upward-facing as well as those with drooping blooms.
