Large-flowered False DandelionAgoseris glauca (Pursh) Raf.
This prairie plant is commonly named for its resemblance to the familiar dandelion weed. It releases milky sap when broken, and has seeds with soft, hair-like bristles that help them drift on the wind. The flowers are pollinated by insects, and are especially attractive to birds, butterflies, and bees. The plants have some medicinal applications. Leaves can also be eaten, and flowers used to make dandelion beer or wine.
