A lot of people love lilies because of their beautiful trumpet-shaped blooms and sweet smell. On the other hand, if you look closely at a lily blossom, you might notice that the number of “petals” doesn’t seem to add up. So how many petals does a lily really have? Let’s find out.
The Perplexing Petal Structure of Lilies
At first glance, lily flowers appear to have six petals. The symmetrical blossoms have six equal-sized flower parts arranged in a circle around the stamens and pistil.
However, botanically speaking, not all six of these flower parts are true “petals.” Lily blooms actually contain three petals and three sepals that look nearly identical.
-
Petals are the colorful parts that attract pollinators.
-
Sepals are leaf-like structures that protect the 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 arrangement of sepals and petals is what makes lilies look like they have more or less petals than they do.
The Signature Trumpet Form of Lily Tepals
The six tepals of lily blooms have a characteristic trumpet shape. The tepals are attached at the flower’s ovary base 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 a hallmark of true lilies in the Lilium genus.
The curved tepals surround the stamens and pistil, which are the reproductive parts in the middle. The edges of the tepals open just enough for pollinators like bees to get to the nectar inside.
The recurved tepal shape maximizes visual impact by creating a showy floral canopy. The tepals also display patterns like speckles, blotches, or contrasting edges to further attract pollinators.
Why Lilies Have 3 Petals and 3 Sepals
Most flowers have either three or four petals and sepals, due to how they develop and genetic limitations. Lily blooms 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. Lily flowers have two whorls – an outer sepal whorl and an inner petal whorl.
-
Each whorl contains three members, as guided by basic genetics. Lilies have three sepals in the outer whorl and three petals in the inner whorl.
-
Symmetry creates visual appeal to attract pollinators from all sides. The six tepals are evenly spaced in a radiating circle for access.
-
Lilies are monocots, which means that their flower parts come in groups of three. Most monocots have petals and sepals in threes.
In short, the lily’s six-tepaled trumpet form satisfies biology, genetics, function, and beauty in one efficient yet stunning package!
Variations Among Lily Species and Cultivars
While most lilies follow the three sepal, three petal formula, some interesting exceptions exist:
-
Some species have over 10 tepals, like the decatepal lily.
-
A few species break symmetry and have four tepals, like Henry’s lily.
-
Double-flowered cultivars have extra petals bred into the blooms.
-
Albino lilies lack pigment so the tepals are white inside and out.
-
Dark nectar guide lines often mark the tepals to point insects to nectar.
So while six petal-like tepals is the norm, lilies do display some fascinating variations. Breeders continue developing exciting new tepal forms as well!
The Role of Lily Tepals
The lily’s showy tepals serve several key roles:
-
Attract pollinators with bright colors, patterns and fragrance.
-
Protect the developing ovary before bloom.
-
Support reproductive parts by holding stamens and stigma in position.
-
Enhance visibility by reflecting light.
-
Repel rain and moisture with thick, waxy surfaces to keep pollen dry.
-
Reorient toward light to maximize sun exposure.
-
Provide a flat, sturdy landing platform for insects to enter the flower.
The lily’s ingenious tepal structure facilitates successful reproduction, allowing the species to thrive. It’s no wonder lilies are so widespread and cherished in gardens!
Demystifying Lily Petal Counts
For lily admirers, the unusual petal numbers can be perplexing. In truth, lilies have three petals and three nearly identical sepals for a total of six petal-like tepals. This design satisfies biology, genetics, function and beauty. While lily petal counting may seem confusing initially, their novel floral anatomy exemplifies nature’s creativity. The next time you enjoy elegant lilies, take a moment to appreciate the hidden complexity within each perfect blossom!
Division 4: American Hybrids
This division consists of cross of Lilium species native to North America, where they grow wild. American hybrids are quite tall, with nodding, downward-facing blossoms on tall, curved pedicels. American hybrids bloom around the end of June into early July.
Division 1: Asiatic Hybrids Found almost anywhere, these hybrids are the easiest to grow. Their flower aspect can be upward-facing, outward-facing, or down-facing, also known also as pendant. Asiatic hybrids are very popular, but unscented. Attractive and long-lasting, they are usually the earliest to bloom in the garden.
Martagon hybrids are known for how tall they are and how many small, strongly curved petals they have on flowers that face downwards or nod. There can be up to 40–50 petals per stem. They are early blooming and thrive in a shady woodland location. Martagon hybrids do not tolerate intense heat, humidity, and direct sunlight as well as other members of the genus Lilium.

FAQ
Can lilies have more than 6 petals?
Flowers: The flowers of lilies are trumpet-shaped and have six petals arranged in two layers. They can range in size from small, delicate blooms to large, showy flowers up to 10 inches (25 cm) in diameter.
How many pedals does a Lilly have?
“True Lilies” belong to the genus Lilium. When the flowers bloom, they are large, colorful, and often fragrant. True Lilies all have 6 petals and 6 stamens with anthers (oblong pods that contain pollen).
How many pistils are on a lily?
There may be a single pistil, as in the lily, or several to many pistils, as in the buttercup. The lobes of the stigma are often characteristic of families or genera; for example, many bellflowers (Campanula) have a distinctive stigma with three curling lobes.
How many petals does a water lily have?
Flowers from these plants smell nice and have at least 50 petals. They are 18 to 46 cm (about 7 to 18 inches) wide. They open white toward evening and shade to pink or reddish two days later before they wither, to be replaced by a large berrylike fruit.
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.
How many petals do lilies have?
Technically, lilies have only three true petals. Sepals are the part of the flower that covers the petals when the flower is in the budding stage. The purpose of the sepal is to protect the petals from weather and predators, like insects. Generally, sepals are green and look like leaves.
Which lilies have 6 petals?
These flowers fall in the genus Lilium in the family Liliaceae. Lilies have six petals and come in nearly every color of the rainbow. There are many other plants with “lily” in their names, such as daylily (genus Hemerocallis), water lily (Nymphaea), lily of the valley (Convallaria), and peace lily (Spathiphyllum).
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. So to recap – lily flowers have:
How many tepals do lilies have?
In truth, lilies have three petals and three nearly identical sepals for a total of six petal-like tepals. This arrangement satisfies biology, genetics, function, and aesthetics in one efficient yet beautiful package. So, counting lily petals might seem hard at first, but their unique flower structure shows how creative nature is.
Why do lilies have petals?
The purpose of petals is to attract pollinators to the flower. 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.
