Weed Identification Tool

Step 1: Select Weed Type

Select the type of weed you are trying to identify:

Cacti
These are spine-covered plants with succulent stems. Green leaves are usually absent. Flowers are typically showy and have numerous waxy petals.
Forb
These herbaceous (non-woody) plants typically produce noticeable flowers. Leaves are often broad with netted veins, but they may also be narrow and veinless.
Grass
These herbaceous (non-woody) plants lack noticeable flowers. The leaves are ribbon-like with parallel veins, and are often tightly rolled.
Woody
Trees, shrubs, and sub-shrubs with obvious woody stems that persist year after year.
