Orange Hawkweed (Hieracium aurantiacum)
Orange hawkweed has matted hairy leaves and handsome flowers, each about an inch in diameter and usually red on the margin, merging into an orange-colored center. The flowering branches, or shoots, grow from a few inches to two feet in height. They are leafless and covered with stiff black hairs.Hawkweeds are aggressive competitors of pasture and range plant species. Orange hawkweed is unpalatable and thus crowds out more palatable species.
Geographic: Orange hawkweed is widely distributed in northeastern Washington with the largest known population in Pend Oreille County. It is occasionally reported from western Washington.
Growth and Development: Orange hawkweed is a perennial plant.
Reproduction: Orange hawkweed reproduces from seeds and stolons and/or rhizomes.
Response to Cultural Methods
In scattered patches of small size, the simplest mode of attack is to dig out the orange hawkweed plants. Make sure that all of the below-ground growth is also removed, since even a small piece if left in the soil may develop into a new plant. These plants should be carried away and either burned or placed in a refuse pile where they can do no harm.
