Thinleaf Sunflower
Helianthus decapetalus
Duration
Perennial
Plant Type
Wildflower

The Thinleaf Sunflower is a great choice for gardeners looking for a showstopping fall-flowering plant. The profuse yellow flowers attract all kinds of pollinators, like Black Swallowtails, and this is the larval host for the Silvery Checkerspot and Gorgone Checkerspot Butterfly. Once the flowers pass, the seeds are pilfered by birds and chipmunks for a late fall snack. The plants prefer partial sun and prefer to stay moist. They can dry out occasionally, making them an ideal plant to neglect. Be careful of loving them too much, as they may become weedy under ideal circumstances. Safe for pets.
