Quick answer: Lily is the correct spelling for the flower and the common noun. Lilly is a variant spelling, mostly used as a proper name or brand name, not as the everyday word for the plant. Example: She placed a white lily on the windowsill.
My neighbor named her daughter Lilly, spelled with two L’s. A few weeks later, she wrote a caption online about the flowers blooming in her garden, calling them “lillies.” A friend gently pointed out that the flower itself is usually spelled lily, with just one L. She laughed and said she genuinely thought both spellings were interchangeable.
That mix-up happens a lot, and honestly, it makes sense. Names don’t always follow the same rules as everyday words. Someone can be named Lilly, while the flower blooming in their yard is still spelled lily. Two different situations, two different accepted spellings.
If lily or lilly has ever left you unsure which one to type, this guide will clear it up for good. We’ll walk through the meaning, the reasoning, and plenty of real examples, so you always know which spelling fits.
Lily or Lilly: Quick Answer
Lily is the correct spelling for the flower.
Lilly is mainly used as a personal name or brand name.
For the plant itself, always use lily.
Examples
- The lily bloomed early this spring.
- Her name is Lilly, spelled with two L’s.
Incorrect Example
- The lilly bloomed early this spring.
What Does “Lily” Mean?
Lily refers to a family of flowering plants known for their large, often fragrant blossoms. It’s also used more broadly to describe anything shaped like or associated with this flower, like a “lily pad” floating on a pond.
Examples
- The garden was filled with white lilies.
- A single lily sat in a glass vase.
- Lily pads covered the surface of the pond.
Whenever you’re writing about the plant, lily is the spelling dictionaries and style guides consistently use.
What Does “Lilly” Mean?
Lilly isn’t really a separate word with its own definition. Instead, it functions almost entirely as a proper noun, most often a person’s first name or part of a brand name. It doesn’t appear in dictionaries as an accepted spelling for the flower itself.
Examples
- Lilly graduated from college last spring.
- The Eli Lilly company develops pharmaceutical products.
- My cousin’s daughter is named Lilly.
Notice how different this feels from lily. One describes a flower. The other identifies a specific person, company, or brand.

Why Are They Spelled Differently?
This distinction isn’t really about grammar rules, like verb endings or plural forms. It’s about the difference between a common noun and a proper noun. Lily, the flower, follows standard dictionary spelling. Lilly, the name, follows whatever spelling a family, company, or individual chooses for that particular name.
Names in English don’t always match dictionary spelling exactly. Parents can spell a name however they’d like, and that choice becomes the correct spelling for that specific person, even if it differs from the everyday word it’s based on.
Quick Way to Tell Them Apart
- Talking about the flower or plant? Use lily.
- Talking about a specific person’s name or a brand? Use Lilly, if that’s how they spell it.

The Usage Rule, Explained Simply

Step-by-Step: Choosing the Right Spelling

Step 2: If yes, use lily, the standard dictionary spelling.
Step 3: If you’re referring to a specific person’s name, check how they spell it.
Step 4: Many people spell their name Lilly, with two L’s, so always confirm before writing it.
Step 5: For brand names, like Eli Lilly, use the company’s official spelling.

Where Does the Word “Lily” Come From?
Lily traces back through Old English and Latin, ultimately connecting to an ancient word for the flower that appeared across several early languages. The flower itself has held symbolic meaning for centuries, often representing purity, renewal, or elegance in art and literature.
As names became more personalized over time, some parents began spelling the name Lilly, with two L’s, likely influenced by how the double-letter pattern appears in other popular names. That stylistic choice eventually became common enough to feel like its own accepted variant, especially for names rather than the flower.
Why Do People Confuse Lily and Lilly?
This mix-up happens for a few clear reasons, and honestly, it makes sense once you break it down.
They Sound Completely Identical

Names Often Get Treated Like Regular Words
People sometimes assume a name’s spelling should match the dictionary word it’s based on.

That makes it easy to accidentally use it for the flower too.
