Antennaria racemosa is a species of flowering plant in the family Asteraceae known by the common name racemose pussytoes.[2] It is native to western North America from British Columbia and Alberta south as far as northern California and Wyoming.[3][4] It grows in mountain forests, generally in moist, partially shaded areas, and often colonizes bare patches of mineral-rich soil, including disturbed areas.[3]
Antennaria racemosa is a glandular perennial herb which may be small, woolly, and matted to nearly hairless and erect to heights near 50 cm (20 inches).[5] It forms basal patches of oval-shaped leaves 3 to 10 centimeters long, fuzzy on the undersides and shiny green above.[5] The patches are connected with stolons covered in leaves.[3] The erect stem bears an inflorescence which can be shaped like a raceme and is often dense, especially in higher elevations, containing several flower heads.[3] The species is dioecious, with male and female plants producing different types of flowers in the heads.[2] The fruit is an achene with a body only about a millimeter long attached to a soft pappus up to 7 millimeters long.[5] The pappus catches the wind, which disperses the seed.[3] The plant also reproduces vegetatively via its creeping stolons.[3]
