Botanical Description
Pilosella officinarum (formerly Hieracium pilosella), the mouse-ear hawkweed, is a low, mat-forming perennial herb of the daisy family spreading by long, leafy, creeping stolons. It forms basal rosettes of small, elliptic to spoon-shaped leaves that are green and bristly above and densely white-felted (woolly) beneath, the contrast giving rise to the 'mouse-ear' name. From each rosette rises a single slender, leafless, hairy flowering stalk 5 to 30 cm tall bearing one lemon-yellow flower head composed entirely of strap-shaped ray florets, the outer ones often streaked red beneath. The fruit is a small ribbed achene topped with a tuft of simple hairs. Native across Europe and temperate Asia and naturalized elsewhere, it grows on dry banks, short grassland, heaths, walls, and other open, well-drained ground.
