Yellow hawkweed has bristly-haired, narrow, elongated leaves four to six inches long. The leaves are attached near ground level and the flowering stalk, arising from the leaf cluster, is leafless. The flowering stalks grow from a few inches to three feet in height; the stems have short, stiff hairs and contain a milky latex sap inside the stem. The flowers, which are about the same shade of yellow as buttercups, occur in heads that are about 3/4 of an inch in diameter Yellow hawkweed is destructive in rich pasturelands and may even invade cultivated fields. Yellow hawkweed is unpalatable and thus crowds out more palatable species.

Habitat: Yellow hawkweed occurs in permanent meadows, rangelands, and pasturest

Growth and Development:  Yellow hawkweed is a perennial plant

Reproduction:  This species can spread by seeds, stolons, and/or rhizomes.

Response to Cultural Methods:  In scattered patches of small size, the simplest mode of attack is to dig them out, making sure that all of the below-ground growth is also removed, since even a small piece may develop into a new plant. These plants should be either burned or placed in a refuse pile where they can do no harm
