Hoary flase yarrow as seen atop Lookout Mt., Badger Creek Wilderness...........July 16, 2017.
Hoary false yarrow is an upright wildflower with cottony, lacy pinnate leaves. The one to several stems are erect, relatively straight, and often unbranched. Plants arise 10-60 cm in height. The leaves are bipinnate to pinnately dissected (See photo below). The leaf segments are thick and curled, so the leaves do not look flat.
The inflorescence is a flat-topped corymb. There are several to many white or pink-tinged disk flowers which look like pincushions. Individual plants grow up to 1.5 feet tall. Flowers from May into September.
Hoary false yarrow may be found on dry, rocky or sandy soils from the lowlands to timberline in the mountains.
Hoary false yarrow may be found from southern British Columbia to southern California, east of the Cascade and Sierra Nevada ranges, east to Colorado and northern Arizona.
