About Anemonastrum narcissiflorum subsp. crinitum (Juz.) Raus
This plant, Anemonastrum narcissiflorum subsp. crinitum (Juz.) Raus, grows to a height of 7 to 60 cm (2+3⁄4 to 23+1⁄2 inches) from a caudex, which is a woody perennial base. Its flowering season runs from spring to mid-summer, and it often continues flowering into late summer.
It produces 3 to 10 basal leaves that are ternate, meaning they are structured with three leaflets each. These leaves have a shape ranging from rounded to rounded triangular, and their petioles measure 4 to 20 millimetres (5⁄32 to 25⁄32 inches) long.
Flowers are borne in umbel clusters that hold 2 to 8 flowers, though they often appear to grow singly. The inflorescence has 3 leaf-like bracts that resemble the plant's basal leaves, but are simpler and much smaller in size, with a pinnatifid shape. The flowers do not have true petals; instead, they have 5 to 9 petal-like sepals that can be white, blue-tinted white, or yellow. Flowers typically contain 40 to 80 stamens, and can have as many as 100 stamens.
After flowering, the plant develops fruits held in rounded heads, attached to pedicels 5 to 14 centimetres (2 to 5+1⁄2 inches) long. The ripe fruits, called achenes, are ellipsoid to ovate in outline and flat in shape, measuring 5 to 9 millimetres (3⁄16 to 11⁄32 inches) long and 4 to 6 millimetres (5⁄32 to 1⁄4 inch) wide. The achenes are winged, hairless, and have curved or recurved beaks that are 0.8 to 1.5 millimetres (0.031 to 0.059 inches) long.
Anemonastrum narcissiflorum, the parent species of this subspecies, is native to northwestern North America and Eurasia. It grows in a range of habitats including high mountain alpine grasslands, thickets, moist grassy meadows, tundra, open woods, roadsides, and pastures.
