How to Identify This Leaf
Follow these simple steps to get instant AI-powered identification
Take a clear photo of the leaf placed flat against a plain background. Show the full leaf shape including the petiole (stem). Use natural lighting for the most accurate color representation.
Our advanced AI model analyzes the leaf's shape, margin pattern, vein arrangement, size proportions, and texture. The system cross-references thousands of verified leaf specimens from botanical databases to identify the parent plant or tree species.
Receive a detailed identification result including the tree or plant species name, common name, family classification, typical habitat, geographic range, and interesting facts about the species. Share or save your results.
Alternative Methods
Leaf Shape Dichotomous Keys
Traditional botanical dichotomous keys guide you through a series of yes/no questions about leaf features — Is it simple or compound? Is the margin smooth, serrated, or lobed? This methodical approach is highly accurate but requires botanical knowledge and patience.
Leaf Rubbing and Pressing
Creating leaf rubbings with crayons or pressing leaves in a book can preserve specimens for later comparison with field guides. This hands-on method is popular for educational activities and nature journaling, allowing careful comparison of details over time.
Bark and Tree Shape Correlation
If you found the leaf under a specific tree, examining the tree's bark texture, overall shape, and branching pattern can help confirm the leaf identification. Combining leaf and bark features significantly narrows down the possible species.
Local Arborist or Nature Center
Local arborists, nature centers, and botanical gardens often provide free tree and plant identification services. They can examine leaves in person and use multiple identification features simultaneously, though this requires a visit.
Photo Quality Tips
- ✓Place the leaf flat on a plain white or light-colored surface and photograph from directly above for the clearest shape outline.
- ✓Ensure the entire leaf is visible in the frame including the petiole (stem) and leaf tip — partial leaves are harder to identify.
- ✓Use natural daylight to accurately capture the leaf's true color, which varies significantly between species.
- ✓Get close enough to show the leaf margin detail (smooth, serrated, lobed, or toothed) as this is a primary identification feature.
Best Practices
- •For compound leaves, photograph the entire leaf including all leaflets attached to the central stalk (rachis).
- •If possible, include both the top (adaxial) and bottom (abaxial) surfaces in separate photos — venation patterns often differ.
- •Choose a mature, fully developed leaf rather than a young, still-expanding leaf for the most accurate identification.
- •Avoid heavily damaged, diseased, or insect-eaten leaves — these missing portions can reduce identification accuracy.
What Can Our Tool Recognize?
AI-powered recognition across multiple categories with high accuracy.
Identify leaves from common deciduous trees that drop their foliage seasonally across temperate regions.
Recognize needles and scale-like leaves from evergreen trees and conifers found worldwide.
Identify leaves from tropical and subtropical trees found in warm climates and botanical gardens.
Recognize leaves from common landscape shrubs, hedging plants, and ornamental bushes.
Identify leaves from vines, climbers, and trailing plants including poison ivy and similar species.
Recognize leaves from herbs, wildflowers, and common garden plants.
Identify leaves displaying fall colors — reds, oranges, yellows, and browns — from deciduous species.
Recognize fronds from palm trees, ferns, and other non-traditional leaf forms.
Why Choose Our Identification Service?
The most accurate, fast, and privacy-focused identification tool available online.
Our AI leaf identifier recognizes over 500 tree and plant species from leaf photos alone. From common backyard oaks to tropical palms, our tool handles the full range of leaf diversity.
Unlike basic image search, we don't just name the leaf — we tell you the complete tree or plant species, its habitat, geographic range, growth characteristics, and interesting ecological facts.
IdentifyThis.app works entirely in your web browser. Simply sign in with Google, upload your photo, and get results instantly from any device.
At just $3/week or $10/month, IdentifyThis.app costs less than PictureThis ($39.99/year) or PlantID ($19.99/year), and includes all identification categories.
Your uploaded leaf photos are processed securely and are never stored, sold, or shared with third parties. All image analysis happens with full data protection compliance.
Our identifier flags leaves from toxic and irritating plants like poison ivy, poison oak, and poison sumac with clear safety warnings so you know which leaves to avoid touching.
Our identifier works with both fresh leaves picked on a walk and pressed or dried herbarium specimens, adapting to different preservation states.

Our AI is specifically trained to extract maximum identification value from leaf photos — analyzing shape geometry, margin patterns, venation, and proportions that general image recognition tools often overlook. This leaf-focused training produces more accurate species identification from a single leaf than generic plant identification tools.
Correctly identifying poison ivy, poison oak, and other irritating plant leaves is essential for hikers, campers, and outdoor workers. Our identifier prioritizes these safety-critical identifications with prominent warnings, helping people avoid painful encounters with toxic plants.
Whether you're a student pressing leaves for a botany project, a hiker curious about trail-side trees, or a parent exploring nature with kids, our leaf identifier transforms any leaf into a learning opportunity with species information, habitat data, and ecological context.
