Antennaria dioica is a herbaceous perennial plant growing to 10–20 cm tall, with a rosette of basal spoon-shaped leaves 4 cm long, and 1 cm broad at their broadest near the apex; and smaller leaves arranged spirally up the flowering stems. The flowers are produced in capitula (flowerheads) 6–12 mm diameter with pale pink ray florets and darker pink disc florets.
