In autumn people find shiny brown nuts on sidewalks and wonder if they can roast them. Our chestnut tree identifier looks at your photo and tells sweet chestnut (American, European or Chinese) apart from horse chestnut and buckeye. That difference matters, because sweet chestnuts are edible while horse chestnuts and buckeyes are poisonous.
How It Works
Photograph a whole leaf and, in late summer or fall, the husk with its nuts both closed and split open. Sweet chestnuts have long single leaves with bristle-tipped teeth and very spiny burs, while horse chestnuts have hand-shaped leaves of five to seven leaflets. The result names the species, explains the clues and includes a clear safety note.
Key Benefits
- Distinguishes edible sweet chestnut from toxic horse chestnut and buckeye
- Checks leaf type, husk spines and nut shape in a single analysis
- Recognizes the rare American chestnut and blight-resistant hybrids
- Identifies the trees in spring by their flower spikes, before nuts appear
- Gives one free identification per day on the website with no account

Frequently Asked Questions
Common questions about chestnut tree identifier
Upload a photo of a leaf plus the nut and husk if available. The AI checks leaf shape and husk spines to tell sweet chestnut from horse chestnut and suggest the species.
Sweet chestnut burs are covered in dense needle-like spines and hold two or three flattened nuts with a pointed tip. Horse chestnut husks are leathery with a few short spikes and hold one or two round, glossy conkers.
Yes, horse chestnuts and buckeyes contain aesculin and saponins that can make people and pets seriously ill. Never eat any chestnut based on an app result alone; confirm with an expert.
Chestnut blight, a fungal disease introduced in the early 1900s, killed most mature American chestnuts. Root sprouts still survive in eastern forests, and breeding programs are working on resistant trees.
