Annual Agoseris
Agoseris heterophylla
Annual Agoseris (Agoseris heterophylla) is a perennial wildflower native to the western United States. It grows to a height of 12-16 inches and has attractive narrow leaves that are greenish-grey in color. Its yellow flowers are borne at the ends of the stems in tight, flat clusters. Attracts bees and butterflies. It is drought tolerant and thrives in full sun to part shade. Prefers well-drained soils and can tolerate high pH. Once established the plant requires little care and maintenance. Transplanting and dividing can be done in early spring for more blooms throughout the growing season. Perfect addition to any wildflower meadow or in rock gardens for vibrant bursts of color.
