Plant Reference
Plant ID flashcards and games
Free · Designed for iPad. Not verified for macOS.
Learn to recognize and name plants, the fun way! Flashcards, quizzes and three daily games, with reviews that return just before you'd forget.
Plant Reference helps you learn plants in a way that sticks: from real photographs, a little each day, with every plant coming back just before you'd forget it.
It's made for horticulture students with an ID exam coming up, for people who work with plants and want the Latin names on hand, and for keen gardeners who'd like to know what they're looking at.
Real photographs, and plenty of them
There are more than 8,000 plants to learn. Most have several photos, so you start to recognize a plant wherever you meet it.
Reviews that plan themselves
Get a plant right and it waits longer before coming back. Miss it and you'll see it again soon. The Daily Mix builds a short session for you each day from the reviews that are due, the plants you find hard and a few new ones.
Six ways to study
• Flashcards, with hints you can take one at a time
• Multiple Choice, with a 50/50 when you're stuck
• Plant Parts, where you build a full botanical name piece by piece
• Writing Test, for typing names from memory, with feedback on your spelling
• Name Game, a fun set of quick mini-games matching names and families
• Glossary Quiz, covering more than 2,000 botanical terms and their meanings
Three daily games
• Daily Plant: one close-up photo and four names. You can zoom out if you need more to go on.
• Keyed Out: each lead describes a real botanical feature. Follow them to the family, genus and species.
• Name That Plant: the clues start with the hardest, and three wrong guesses end the round.
Older puzzles stay in the archive, so you can practice on the ones you missed.
Plants in detail
Plant pages cover helpful plant info like sun, water and hardiness zones, native range, suggested uses and how to identify the plant. Tap a highlighted botanical term to see what it means, or tap the speaker to hear the scientific name out loud.
You can search the whole catalog or narrow it down by hardiness zone, sun, water, soil, height, bloom season, flower color, wildlife and more.
Scientific names, properly formatted
Botanical names are set the way they should be, with genus and species in italics and cultivars in quotes. The clever part is that each name part has its own color, so you can see how a name is built, helping it make sense in your mind, and making it stick.
Plant sets for your class or garden
Make a set from your school's class plant list or your own garden and study just those plants. You can also browse and follow sets that other people have published, including sets built from the plant lists of horticultural schools, botanic gardens and nurseries in the US and UK. Save a set to your device to keep studying without a cell signal, and your answers will sync when you're back online. Sightings let you keep count of the times you've seen a plant in person to help with in person test tracking.
Study your way
Some people love a streak and some don't. Calm mode hides streaks, points, levels, the leaderboard and celebrations, and your progress still counts.
Plant Reference also works with VoiceOver, which reads scientific names with their pronunciation, along with Voice Control, Larger Text and Dark Mode. Reading options include upright names and extra spacing.
Plant Reference is free, with no ads and no tracking. You can start right away without an account. If you sign up later, your progress comes with you, and the same account works at plantref.org.
