Plant identification
How to identify a houseplant from a photo
By Bloom team ·
An unlabeled plant is a small mystery. A clear photo can give you a starting point, and a few extra observations help you decide whether a suggested name fits.
Start here
Start with the whole plant, then look closely at leaves and stems. Treat an app result as a candidate to check.
Take a useful set of photos
- Clean the camera lens and choose an in-focus image with the plant well lit, rather than silhouetted against a bright window.
- Take one photo of the whole plant so its overall shape is visible.
- Add a close view of a leaf, its underside and where it joins the stem. Include flowers or buds if present.
- Keep the clearest photos from a few angles. A ruler beside a detail can provide scale when asking someone for help.
Compare more than the leaf color
Leaf shape, edges, veins and the way leaves are arranged along a stem are useful identifying features. Compare those details with a reliable description of the suggested plant.
Write down both the suggested name and the features you can actually see. If an important feature does not fit, keep the identification open instead of forcing a match.

A lookalike example: pothos and heartleaf philodendron
Both are familiar trailing houseplants. Illinois Extension points to new growth as one useful clue: philodendron leaves emerge from a separate thin sheath, called a cataphyll, while new pothos leaves extend from an existing leaf. A close view of that new growth can be more helpful than another distant photo.
This is one comparison clue, not a universal plant-identification shortcut. Use several matching features before settling on a name.

What to do when the result is uncertain
- Retake a blurry or backlit photo before trying another identification.
- Check any original label and ask the nursery or person who gave you the plant.
- Keep the photo set and your observations together. They are useful when seeking help from a local extension service.
- Wait to make a major care change until the suggested identity makes sense for the plant in front of you.
Photo identification can be wrong. A confidence label is not proof of identity, and an app result should not be used to decide whether an unfamiliar plant is safe to eat.
