About plant names...

White pasqueflowers like higher elevations along the west coast of North America.

Identification: I still haven't seen a white pasqueflower in person, but when I spied a group of cotton balls bobbing in the volcanic soil on the roadside on the way to Crater Lake on Mt. Mazama, I was captivated. Took me awhile to identify them. Flowers are white or slightly yellowish, 1¼-2″ (3.2-5 cm) across, with 8 petals and yellow centers. Each stem bears a single flower. Seedheads are roughly circular, slightly elongated, a bit shaggy looking, grayish white, soft looking. At close range there are tiny red threads. Leaves are light green, fernlike. The plants are 8-24″ (20-60 cm) high. These plants are found at high elevations, from about the tree line to about 1.9 mi (3 km).
