Common Yarrow (Achillea millefolium), with its delicate-looking feathery foliage, is a hardy plant found all over California. Its flowers are a pollen source for bees, butterflies, and ladybugs, and many species of moth larvae feed on it. It is found that several cavity-nesting birds line their nests with Common Yarrow leaves to reduce
parasites. Native American tribes across the continent used Common Yarrow as medicine.
