A weed is a plant growing where it is unwanted. A species match does not establish whether it is invasive in your area or recommend a treatment.

Photo tips for weed identification
- Photograph one plant rather than a patch containing several different species.
- Capture a mature leaf and show how it attaches to the stem.
- If the plant is flowering, try a bloom photo with Flower selected.
- For grass-like plants, include a seed head or whole-plant view when available.
Weed identifier questions
How can I identify a weed in my garden?
Upload a clear photo of the unfamiliar plant, keeping its leaves, flowers or growth habit visible. Compare the suggested species before researching its role in your garden.
Does a match mean the plant is invasive?
No. Whether a species is invasive depends on location and local guidance. Check the suggested name with your local extension service or invasive-species authority.
Can this tool identify a seedling?
Seedlings often lack the features that distinguish mature plants. You may get broad or uncertain matches; try again when true leaves or flowers are visible.
