Compact cluster of 5 or more dandelion-like flowers on short hairy stalks at the top of the plant. Flowers are ¾ to 1 inch across, deep red-orange to orange to yellow-orange, often fading to yellow in the center. The bracts behind the flower are densely covered in glandular hairs.
Leaves and stem:
Leaves mostly surround the base of the plant, 2 to 5 inches long and to 1 inch wide, pointed or rounded at the tip, and toothless. 1 or 2 small leaves may also be alternately attached on the lower stem. The leaves and stem are both covered in long hairs.
Orange Hawkweed is highly invasive, the largest infestations being in the counties around Duluth, where it first arrived in Minnesota. It has since been spreading south and west, and is likely very under-reported in the state. Large mono-cultures can be seen along roadsides into Aitkin county, at least. When not in bloom it resembles Meadow Hawkweed (Hieracium caespitosum), and often is found growing with it and its cousin Glaucous King-devil (Hieracium piloselloides).
