Description

This population of this wide-ranging native was grown from seed collected in the Sierra foothills of Placer County, and by division ever since. It is relatively large and robust for the species with flowers of about four inches in diameter. It would be a great choice for a butterfly garden. With regular to occasional water, this yarrow will spread by underground rhizomes. With little or no water after established yarrow will go partially or entirely dormant. Spent flowers and dry leaves should be removed to improve the plant’s overall appearance.
