So named for the sweet resin that has been used as a gum by Native American youth, Rosinweed (Silphium integrifolium) is another prairie native sunflower. It grows quite tall, as most sunflower types, and blooms a little earlier than other types. Unlike other sunflowers, Rosinweed, has its fertile florets on the outer edge while most sunflowers’ fertile florest are centermost.

Copyright 2023 Pamela BreitbergNotice how these seedheads are centered in the flower while the Rosinweed shown in above photos have the seedheads in the outer rim of the cores. I will talk about this sunflower, Cup Plant in another post. Copyright 2023 Pamela Breitberg
I absolutely adore Sunflowers.
