Inspect the leaves of the plant. Wild garlic plants have round and flat leaves that emerge from the bulb. The leaves often range from 6- to 24-inches.
Smell the plant. Wild garlic has an onion or garlic scent that you will not confuse with any other type of smell.
Pull the plants out of the ground. The roots have an oval shape and a papery exterior. Sometimes smaller bulbs will grow off the larger bulb. Small roots are attached to the bottom of the bulbs.
Look for small bell-shaped flowers on the wild garlic. The flowers grow in clusters on a long stem. The flowers can be white, pink or green. Oval-shaped bulblets will replace the flowers later in the season.
