How does the butterfly help pollinate the prairie plants? The prairie blazingstar is one of the most beautiful flowers on the tallgrass prairie. It has magenta colored flowers on a spike at the top of its stalk. The stalk is often up to 5 feet high. Many kinds of butterflies are attracted to this flower. When the butterfly visits a prairie blazingstar, it picks up pollen on its furry body. Then it flies to another prairie blazinstar and drops off its cargo, which pollinates the plant! Sweet coneflower can grow to height of 6 feet if planted in moist soil. The purple coneflower is used by many people in their gardens at home. See how large the orange-colored cone is? This is the part of the flower which produces seeds after the purple petals fall off. Birds like goldfinches love to eat these seeds.
