National parks: Yarrow - public domain image

While visitors often look for the colorful subalpine wildflowers, another wildflower Yarrow (Achillea millefolium) often goes overlooked. Yarrow is a common and versatile, growing widely from low to high elevations and so is often dismissed. However this unobtrusive plant with its tiny white flowers is also know for its medicinal properties. Tribes such as the Squamish used it to cure measles, while the Squaxin liked it as a stomach tonic. It was used for everything from cold medicine to wound poultice.
