Tree identification from a photo

Trees are easiest to name from a close photo of a single leaf (both sides if you can), plus the bark and any fruit, cones or seeds. In winter, a twig with its buds is often enough for an expert, and the AI looks at the same clues.

Take or choose a photo
One leaf, flower or the whole plant, in focus. Stays private: it is sent only to identify it and is not stored.

What to photograph

  1. One whole leaf, flat, filling the frame, including the stalk
  2. Bark at chest height
  3. Fruit, nuts, cones or seed pods, even from the ground below
  4. The whole tree from a distance for its shape

Features that separate look-alikes

Leaf arrangement
Opposite (pairs) or alternate (staggered) along the twig. Only a few big groups of North American trees have opposite leaves.
Simple or compound
A compound leaf is split into leaflets on one stalk (ash, walnut, locust). Look for the bud: it sits at the base of the whole leaf, not each leaflet.
Leaf edge
Smooth (entire), toothed or lobed. Oaks have lobes; elms and birches have toothed edges.
Needles
Pines have needles in bundles of 2, 3 or 5; spruce needles are single, square and sharp; fir needles are flat and soft.

Questions gardeners ask

Can you identify a tree from its bark alone?

Sometimes: birch, sycamore, shagbark hickory and many pines have distinctive bark. For most trees, leaves, buds or fruit give a far more reliable answer.

How do I identify a tree in winter?

Photograph a twig showing bud shape and arrangement, the bark, and any leftover fruit or leaves on the ground.
