Seed Identifier

A seed identifier names a seed or seed pod from a photo of its size, shape, and surface. Loose seeds are one of the trickier things to identify because they are small, similar, and stripped of the leaves and flowers that usually give a plant away. The right photo, with a clear scale, makes it possible.

This page helps gardeners with unlabeled saved seeds, collectors sorting a seed swap, and anyone curious about a pod, nut, or winged seed found on the ground. Upload a sharp, well-lit photo of the seed beside a ruler, and the tool reads the features that distinguish one seed from another.

Because seed identification depends heavily on exact size and fine surface detail, the strongest results come from a scaled photo of the seed, a close-up of its surface, and, when available, the pod or fruit it came from. A quick note about where the seed came from narrows the field further.

Four features carry most of the weight in seed identification. Size is first and most important, because seeds that look identical in a photo can be told apart by a millimeter or two, which is why a ruler or coin belongs in every shot. Shape follows: round, oval, kidney-shaped, flat and disk-like, teardrop, or angular.

Color and pattern add detail, from solid tan and black to speckled, mottled, or striped seed coats. Surface texture completes the picture, whether the seed is smooth and glossy, ridged, pitted, netted, or covered in fine hairs.

Many seeds also carry a dispersal feature that gives them away instantly: a papery wing that spins, a silky tuft that floats, a hook that catches on fur, or a hard shell. Capturing these alongside the seed's basic dimensions gives the identifier a strong, specific set of clues.

When a seed comes from a pod, capsule, cone, or fruit, that container is frequently the best clue of all. A seed pod varies in ways that are highly specific: a long bean-like pod, a papery lantern, a bristly capsule, a woody cone, or a fleshy fruit each point to particular plant families.

How the pod opens matters too. Some split neatly down two seams, some pop explosively, some release seeds through tiny pores, and some never open at all. The arrangement of seeds inside, in a single row, a spiral, or a packed cluster, adds even more.

So whenever you have the pod, photograph it with the seeds. A handful of loose brown seeds might match dozens of plants, but the same seeds shown inside their distinctive pod often narrow immediately to one. Include both the intact pod and an open one if you have them.

Knowing roughly where a seed came from steers the identification. Flower seeds saved from the garden are a common case, especially once packets are lost; they range from the flat black disks of sunflowers to the tiny dust-like seeds of poppies. Vegetable seeds are widely searched for the same reason, and many, like beans, squash, and tomato seeds, have familiar shapes.

Tree seeds are their own category, including winged maple samaras, acorns, ash keys, pine seeds shaken from cones, and an array of nuts. Their wings, caps, and cones are strong identifying features. Wild and weed seeds often carry burrs, hooks, or parachutes built for dispersal.

Add whatever context you have, whether the seed was saved, foraged, or found, and where. That single note tells the seed identifier which of these worlds to search first, making the match faster and more reliable. Remember that a name is not a green light to plant or eat an unknown seed.
