If you have ever written about flowers and paused at “lilies or lillies?”, you are not alone. The two spellings look almost identical, so it is easy to add an extra l by mistake.
The correct spelling is lilies. Lillies is incorrect when you mean the plural of lily. Major dictionaries list lilies as the plural form of lily.
So, if you are talking about more than one lily, write:
One lily → two lilies
In this guide, you will learn why lilies is correct, how the spelling rule works, when to use lily, and how to remember the correct form without second-guessing yourself.

Lilies or Lillies: Which Spelling Is Correct?
The correct spelling is lilies.
Lillies is a common spelling mistake. The confusion usually happens because English has many words where letters are doubled when suffixes are added. However, lily follows a different pluralization pattern.
The Correct Form Is “Lilies”
Lily is the singular noun.
Lilies is its plural form.
| Singular | Plural | Correct? |
|---|---|---|
| lily | lilies | ✅ Correct |
| lily | lillies | ❌ Incorrect |
| lily | lilys | ❌ Incorrect |
For example:
- I planted one lily in the garden.
- The garden is full of beautiful lilies.
- She bought three white lilies.
- The vase contains several lilies.
Cambridge Dictionary specifically gives lilies as the plural of lily, while Dictionary.com also lists lilies under the noun’s plural forms.

Why “Lillies” Looks Tempting
The incorrect form lillies looks believable because the original word contains two consecutive syllables that sound similar: lil-y.
When people quickly form the plural, they may think the spelling should become:
lily → lillies
But English does not double the l here.
Instead, the final y changes to ie, followed by s:
lily → lilies
A Quick Memory Trick
Think of the transformation this way:
lil + y → lil + ies
The first part, lil, stays exactly the same.
Only the final y changes.
lily → lilies
Not:
lily → lillies
That simple visual pattern can help you avoid the extra l.
Why Is “Lilies” the Correct Plural of Lily?
The spelling becomes easier once you understand the English plural rule for words ending in a consonant followed by y.
The “Y” to “IES” Rule
When a common noun ends in a consonant + y, the usual plural pattern is to change y to i and add es.
For example:
- baby → babies
- city → cities
- family → families
- story → stories
- country → countries
- lily → lilies
Grammarly’s updated plural-noun guidance explains this same consonant-plus-y pattern and gives examples such as baby → babies and city → cities.

Lily Follows the Same Pattern
Look closely at the ending:
lily
The letter immediately before y is l, which is a consonant.
Therefore:
lily → lilies
The spelling changes only at the end.
| Singular | Change | Plural |
|---|---|---|
| lily | y → ies | lilies |
| baby | y → ies | babies |
| city | y → ies | cities |
| story | y → ies | stories |
| family | y → ies | families |
This is why lilies is not an arbitrary spelling. It follows a familiar English pluralization pattern.
What About Words Ending in a Vowel + Y?
There is an important difference.
When a noun ends in a vowel + y, we normally keep the y and add s.
For example:
- boy → boys
- toy → toys
- key → keys
- day → days
Compare:
lily → lilies
but
boy → boys
The letter immediately before y determines which pattern applies.

What Does “Lily” and “Lilies” Mean?
The word lily refers to a flowering plant, and lilies simply means more than one lily. Cambridge defines lily as a plant with large flowers that are often white.
Meaning of “Lily”
Lily is the singular form.
Example:
A white lily was growing beside the pond.
Here, the sentence describes one flower.
Meaning of “Lilies”
Lilies is the plural form.
Example:
The garden was filled with colorful lilies.
Here, the sentence refers to multiple flowers.

Common Lily Expressions

- water lily
- lily of the valley
- lily bulb
- lily garden
For example:

A Simple Guide to Spelling Lilies Correctly
Instead of memorizing the word as a completely separate spelling, use a short process.
Step 1: Start With “Lily”
The singular form is:
lily
Do not begin with lillies. Start with the dictionary form.
Step 2: Identify the Final Letter
The word ends in:
-y
The letter before y is l, a consonant.
Step 3: Apply the Plural Rule
For a common noun ending in consonant + y, change:
y → ies
So:
lily → lilies
Step 4: Check for an Extra Letter
Make sure you have not accidentally added another l.
Correct:
L I L I E S
Incorrect:
L I L L I E S
Step 5: Read the Whole Word
Before publishing, submitting homework, or sending your message, quickly check:
lilies
If you see lillies, remove the extra l.

2025–2026 Reference and Data Snapshot
Spelling is a language question, so dictionary and grammar references are more useful here than general search-volume estimates. Current reference material continues to support lilies as the standard plural of lily.
Current Grammar Guidance
Grammarly’s plural-noun guide was updated on January 16, 2025, and explains that nouns ending in a consonant followed by y generally change y to ies when pluralized.
That rule directly explains:
lily → lilies
A 2026 Flower-Industry Data Point
The latest USDA National Agricultural Statistics Service horticulture table published in 2026 reports 2024 U.S. cut-flower sales. Its table includes calla lilies, with approximately 2.406 million stems sold and a reported value of about $3.476 million.
This is useful context because lilies is not merely a classroom spelling example; lily names are also commonly used in real horticulture and flower-market contexts.
What the Data Tells Us
The important takeaway is simple:
- Grammar references: lily → lilies
- Current dictionary references: lily → lilies
- Horticultural usage: “calla lilies” is used as a standard plant/flower term
- Incorrect spelling: lillies
Therefore, if you are writing a gardening article, product description, school assignment, or social media caption, lilies is the spelling to use.
Practical Case Study: Fixing “Lillies” in a Flower Description
Imagine a small flower shop preparing a website description for a spring collection. The original draft says:
“Our beautiful lillies are perfect for birthdays, weddings, and spring celebrations.”
At first glance, the sentence looks completely normal. However, the plural noun contains an unnecessary second l.
A quick grammar check identifies the singular form:
lily
Next, apply the consonant + y plural rule:
lily → lilies
The corrected sentence becomes:
“Our beautiful lilies are perfect for birthdays, weddings, and spring celebrations.”
This small correction matters because the website may use the word repeatedly in product names, headings, descriptions, image captions, and promotional material.
Correct spelling makes the content look more polished and helps readers trust the information.
The same process works for a student writing about flowers, a gardener creating plant labels, or a blogger publishing an article.

Instead of trying to remember whether there are two l letters, return to the singular word and apply the plural rule.
This example also shows why understanding the rule is more useful than memorizing one word. Once you know consonant + y → ies, words such as lily → lilies, family → families, and story → stories become easier to spell correctly.
Quick Comparison: Lilies vs. Lillies
| Feature | Lilies | Lillies |
|---|---|---|
| Correct spelling | ✅ Yes | ❌ No |
| Singular form | lily | lily |
| Plural form | lilies | Incorrect |
| Meaning | More than one lily | Not the standard plural |
| Grammar pattern | y → ies | Incorrect letter doubling |
| Example | Three lilies bloomed. | Three lillies bloomed. ❌ |
The easiest rule to remember is:
Lily + plural = lilies
Not:
Lily + plural = lillies

Common Mistakes With Lily and Lilies
Mistake 1: Writing “Lillies”
This is the most common confusion in this comparison.
❌ lillies
✅ lilies
The extra l does not belong in the plural.
Mistake 2: Writing “Lilys”
Some writers remember that plurals often take s and simply write:
❌ lilys
But lily ends in consonant + y, so the standard plural is:
✅ lilies
Mistake 3: Using an Apostrophe
An apostrophe is not needed just because a word is plural.
❌ lily’s for more than one flower
✅ lilies for more than one flower
The form lily’s can be possessive, as in:
The lily’s petals were soft.
Here, the apostrophe indicates that something belongs to one lily.
Mistake 4: Confusing “Lily” With “Lilies”
Use lily for one:
There is one lily in the vase.
Use lilies for more than one:
There are five lilies in the vase.
This singular-versus-plural distinction is simple once you focus on the number of flowers.
