A purple flower in the park's flowerbed, a tree laden with fruit on the street by your hotel, the plant you received as a gift and have no idea how to water. Point your phone's camera, tap a button, and in seconds, the answer appears on the screen: its common name, its scientific name, how much light it needs, and whether it's dangerous for your cat.
In this guide you will learn how to identify plants using your cell phone: what an app can discover with a single photo, how to use PictureThis step by step, which other apps do the same for free, how to take the right photo, and which common plants require attention at home with pets.

How to take the perfect photo
The app sees what the photo shows. The better the detail, the more accurate the result.
- Flower first: Flowers and fruits are the parts that most differentiate one species from another.
- Leaf up close: Fill the screen with a single sheet of paper, facing forward, with the entire outline showing.
- One plant per photo: If the pot contains two species together, the app may mix them.
- Natural light: Near a window or outdoors, without a flash.
- Details matter: Thorns, hairs on the stem, and buds help to distinguish similar plants.
- More than one angle: The entire plant, the flower, and the leaf. Together, the photos complete the identification.
The plants that everyone wants to identify.
Some species decorate homes all over the world and almost always arrive without a label:
- Monstera deliciosa (Swiss cheese plant): The huge, cut-out leaves that have become a decorating craze.
- Snake plant (Dracaena trifasciata): Tough, upright leaves that can tolerate little light and little water.
- Boa constrictor (Epipremnum aureum): A climbing plant with heart-shaped leaves that spreads across any bookshelf.
- Peace lily (Spathiphyllum): White flowers and glossy leaves, a sure presence in offices.
- Zamioculca (Zamioculcas zamiifolia): Leaves so glossy they look like plastic.
- Succulents: Hundreds of species look alike, which is precisely where the app makes the biggest difference.
Toxic plant: the warning that protects your pet.
Many beautiful potted plants are harmful to dogs and cats. Identifying them before bringing them home avoids surprises.
- Lilies (Lilium) and daylilies (Hemerocallis): For cats, even a piece of leaf or pollen licked from their fur can cause kidney failure.
- Dumb cane (Dieffenbachia): The sap irritates the mouth and throat of anyone who chews the leaf.
- Boa constrictor and Monstera deliciosa: They contain crystals that irritate the mouths of dogs and cats.
- Sago (Cycas revoluta): All parts are toxic to dogs, especially the seeds, and the poison attacks the liver.
PictureThis displays this alert on the plant's information sheet. If your pet has chewed on a suspicious leaf, photograph the plant and take the information to your veterinarian.
Tips for making the most of it
- Take the app with you on your walk: A trail, park, or trip can turn into a hunt for species.
- Design your garden in the app: Each saved plant gets its own watering reminder.
- Take a photo before you buy: At the nursery, find out if the plant can tolerate the light in your home.
- Compare two apps: When the results show two similar species, take the same photo in PlantNet or Google Lens.
- Help science: On PlantNet and iNaturalist, your photos fuel research on the world's flora.
- Plant or mushroom to eat: Only after confirmation from a specialist who has the plant in hand.
