"Anemone narcissiflora" (Narcissus-flowered anemone) is a herbaceous plant species in the genus "Anemone" and family Ranunculaceae. Plants grow 7 to 60 cm tall, from a caudice (woody-like perennial base), flowering spring to mid summer but often found flowering till late summer. Plants with 3-10 basal leaves that are ternate (arranged with three leaflets), rounded to rounded triangular in shape with 40 to 200 mm long petioles. The flowers are produced in inflorescences with 2 to 8 flowers, in umbels, but often also produced singularly. The inflorescence have 3 leaf-like bracts similar in appearance to the basal leaves but simple and greatly reduced in size, pinnatifid in shape. Flowers lack petals, the sepals number 5-9 per flower and are white, white tinted blue or yellow in color. The flowers have 40 to 80 stamens but can have up to 100. After flowering, fruits are produced in rounded heads with 5-14 cm long pedicels. When the fruits, called achenes, are ripe they are ellipsoid to ovate in outline, flat in shape and 5 to 9 mm long and 4-6 mm wide. The achenes are winged with no hairs and have 0.8-1.5 mm long beaks that are curved or recurved.

"Anemone narcissiflora" is native to north western North America and Eurasia where it can be found growing in high mountain alpine grasslands, in thickets, grassy meadows with moist soils, tundra, open woods, along roadsides and in pastures. This species is very variable and at least 12 varieties are generally recognized with even more proposed by other authorities. The name of the species has been in dispute and some have listed it as "Anemone narcissifolia" but "Anemone narcissiflora" was proposed for conservation. [cite book
