Which path is best for me?

I don't know much about plants. Where do I begin?

No problem! We're here to help. We recommend that you find a plant that is in a convenient place for you, such as a street tree on the block where you live, a plant in your yard, at your workplace, schoolyard or in a nearby park.

Once you've located your plant, you'll need to identify it. Don't know what the plant is? Visit the "I need help identifying my plant!" section below.

If you know what your plant is already, visit the "I've identified my plant and am ready to make observations" section below.

I need help identifying my plant!

We can help with that too! Consult a plant field guide for your area OR

Take pictures of your plant (if possible, of the leaves, flowers, fruits, and/or bark (you won't always be able to see all of these features)

Bring or email your pictures to your local plant experts such as staff at a nursery, a local biology teacher, an Extension expert or botanical/native plant society for your state and ask them for help with identification.

Still stuck? Email your photos to and we can try to help you as well!

Once you know what your plant is, read through the "I found a plant and know what it is" section below.

I've identified my plant and am ready to make observations!
