How to identify plants on iPhone, with or without an app

Why Look Up sometimes doesn't appear

"Plant identification iPhone not working" is one of the most common searches about this feature. Work through these in order:

1. No stars on the Info button. Apple's wording is plain: if the Info button doesn't have a star, Visual Look Up isn't available yet for that photo. Often the plant simply isn't the clear subject of the photo. Walk closer so one flower or one leaf fills most of the frame, tap the screen on it to focus, and take a new photo.
2. An older iOS. Visual Look Up needs iOS 15 or later on iPhone. Check Settings > General > About.
3. An unsupported language or region. Compare your iPhone's language with the list above. Apple doesn't promise the feature everywhere.
4. You're in the Camera, not Photos. Visual Look Up works on photos and images you've already taken. For a live view through the camera, use Google Lens or Visual Intelligence (below).
5. The plant is a cultivar or a rare species. Look Up may return only the broad name, or nothing useful. A closer shot of the flower helps; so does a second tool.

Visual Intelligence on Apple Intelligence iPhones

On newer iPhones, Apple's Visual Intelligence works live from the camera and can identify plants and animals. Apple's guide says Apple Intelligence on iOS 27 or later runs on iPhone 15 Pro, iPhone 15 Pro Max and iPhone 16 models or later, and isn't available in all languages or regions. Activate it by clicking and holding the Camera Control on supported models, or from the Action button, a Lock Screen control or Control Center. Point the camera at the plant, then tap the result at the bottom of the screen.

Google Lens in the Google app

Google Lens on iPhone lives in the Google app (and in Chrome). Google's help page Search with an image on Google asks only for the latest version of the Google app, and even uses a plant as its example. The steps:

1. Open the Google app.
2. In the search bar, tap Google Lens.
3. Point the camera at the plant and tap Search, or tap Photo picker to choose a photo you already took.
4. Drag the corners of the box around the flower or leaf to search just that part.
5. In the Google app, tap Add to your search and type a word such as "houseplant" or "leaf spots" to refine it.

Google says results can include AI overviews, search results for objects in the image, similar images, and websites with the same or a similar image. The Google app is free to download from the App Store. Lens is also one of the few free tools a published study has measured: on plants of the British flora it named 45% of samples correctly to species on the first answer, third of nine apps. The details, and what that number does and doesn't mean, are in how accurate plant identification apps are.

When a dedicated app does better, and what each costs

The free tools stop at a name and a page of search results. A plant app is worth installing when you need one of these:

• A health check. Yellow leaves, spots or wilting need a diagnosis, not a name.
• Care notes for that plant. Watering, light and pruning advice tied to the species in the photo.
• Follow-up questions. "Will it survive a north-facing window?" is not something Look Up answers.
• A record. A history of what you identified, and where.
• A list of candidates. Some apps show several possible species, which helps when the first answer looks wrong.

What each option costs, only as each publisher states it (read October 21, 2026):

Plant Identifier, the app this site belongs to, is one of the dedicated options. On the Home screen, tap Identify a Plant and take one photo or choose one from your library. The result gives the common and scientific names, characteristics, origin and growing conditions. The same photo can go through Diagnose (a health check with a severity badge), Toxicology (AI-written notes for people, dogs and cats), Care Guide, Light and Water Calculator. Three suggested questions and a chat box sit under each result, and the Plant Expert tab answers general questions. Finds land in a Plant History, a Collection and a Plant Map. It needs iOS 16 or later and an internet connection, because the photo is sent to a cloud AI model. It shows one name, with no confidence score and no list of alternatives, so for a plant that matters, check the result as described in how to identify plants.

If all you want is a name now and then, the free routes above are enough. The free plant identification apps page compares them in more depth.

Photos that give any tool a fair chance

Every tool on this page reads the same thing: your photo. Fill the frame with one flower, or one leaf with its top side showing, and take a second photo of the leaf underside and a third of the whole plant. Shoot in soft light, tap to focus, and walk closer instead of zooming. If a result looks wrong, photograph a different part of the plant rather than the same leaf again. The full shot list is in how to photograph a plant for identification.
