Using the Wildflower Identification Tool

The identification tool is intended to help hobbiests identify wildflowers based on easily observable characteristics. The database is searched for flowers that have ALL of the characteristics that you selected, so leave the "search all" option selected for any information that your're not sure of. Because we're looking for characteristics that are obvious to the untrained eye, we've taken some liberty with the detailed biology. Click the info icons for more details.

We started out as wildflowers from the bicycle trails of western Pennsylvania, but we've grown!

Flower Shape


Height: Full height of the mature plant, in feet.

Flower width: For round and flattish flowers, the diameter of in individual blossom. For more irregular flowers, the longest dimension of the blossom. For clusters of flowers, use the size of the individual blossoms, even if they're tiny. For example, the flower size is 0.125 inches, even though the cluster (which you might consider to be the flower at first glance) measures 3 inches or more.


Although this is probably the most obvious characteristic, it is also the most variable. We've tried to group colors into a few categories, but one flower may occur in more than one color category.

Bloom Month

The month when you found the flower blooming. The data have been assigned based on the northeastern US, so you may need to make adjustments for your location. Also, variations in weather from year to year will affect when some flowers bloom.

Leaf Shape

Select the shape that best describes the leaves of the plant. If the plant has multiple leaflets coming from a single stalk, select divided, reguardless of the characteristics of the individual leaflets.

If a plant has two or more types of leaves, select multiple.
