Yarrows are easy to grow, low-growing, spreading herbaceous perennials with finely divided aromatic leaves that inhabit many temperate regions in the Northern Hemisphere, including California. Abundant flowers rise above the foliage in spring and well into summer and provide an important nectar source for pollinators and insects. Yarrow can help to stabilize slopes and is a good addition to the upper level of rain gardens and swales. It is also a good groundcover plant for lawn replacement and creating native meadows. Colors include white, yellow, pink, and red.
