Summary
Hieracium scouleri, commonly known as Scouler’s woollyweed, is a perennial herb native to a variety of habitats including open woodlands, meadows, and forest clearings in western North America, from British Columbia and Alberta to northern California and Utah. It typically grows to a height of 12-28 inches (30-71 cm) and is characterized by a basal rosette of long, narrow leaves that are 4-8 inches long and generally hairy. The erect stem supports an inflorescence with each flower head showcasing large, curling bracts with glandular hairs and bright yellow ray florets, which bloom in the late spring to summer.
Scouler’s woollyweed is appreciated for its bright yellow flowers that add a splash of color to wildflower gardens and naturalized areas. It is relatively low maintenance and can be used to attract pollinators such as bees and butterflies. This plant prefers well-drained soils and can tolerate a range of light conditions, from full sun to partial shade. While it is not typically grown for culinary or medicinal purposes, it can be a valuable addition to native plant gardens and restoration projects.CC BY-SA 4.0
