}}Askellia elegans (elegant hawksbeard)[6] is a species of North American plants in the dandelion tribe within the sunflower family. It is native to central and western Canada (Yukon, Northwest Territories, British Columbia, Alberta, Saskatchewan, Manitoba, Ontario) and the northwestern United States (Alaska, Montana, Wyoming).[7]Askellia elegans is a perennial up to 30 cm (12 inches) tall, with a deep taproot and large underground caudex. Stems are sometimes erect, but sometimes trailing along the ground. One plant can have more than 100 small flower heads, each with 6-10 yellow ray florets but no disc florets.[8] References1. ^W.A.
