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.

This native rocket is a biannual or perennial found in wetter meadow habitats and ditches in the Willamette Valley. It has small yellow flowers and clasping pinnately divided leaves.
