Askellia pygmaea (dwarf alpine hawksbeard)[2] is a species of Asian and North American plants in the dandelion tribe within the sunflower family. It is native to western, northern, and eastern Canada (Yukon, Northwest Territories, British Columbia, Alberta, Nunavut, Quebec, Labrador, Newfoundland), the western United States (Alaska, Montana, Wyoming, Colorado, Idaho, Utah, Nevada, Washington, Oregon, California), Russia, Mongolia, Kazakhstan, and western China (Tibet + Xinjiang).[3][4]
Askellia pygmaea is a perennial up to 20 cm (8 inches) tall, with a deep taproot and spreading by means of underground rhizomes thus forming dense clumps. Stems are sometimes erect, but sometimes trailing along the ground. One plant can have more than 80 small flower heads, each with 9-12 yellow ray florets but no disc florets.[5][4]
