This sturdy native grows a single unbranched stem topped by several bright 2-3" sunflower-like flowers. Its common name comes from the gummy, fragrant resin produced by members of the Silphium genus. Supports a variety of pollinators. Drought-tolerant. Photo by Krzysztof Ziarnek, Missouri Botanical Gardens (Creative Commons license).
