Large-flowered agoseris is found on thin-soiled upland prairies and rocky balds. It has a large rosette of cut-leaves and dandelion-type flowers that close by mid-morning. The flowers become a big white ball of fluff when in seed. As with our lawn dandelion, it will re-flower after it is cut. 1-2 ft.
Flowers are large and beautiful, fringed, bright yellow, and often with a magenta center. The foliage is aromatic (sweet), it flowers for an extended period (up to 2 mo.) but flowers close by mid-morning, 4-5 ft tall (in garden or without competition). The seed is a small sunflower seed that attracts many birds.
