Silphium integrifolium

Why this plant is called a “Weed” is beyond us!  Rosin Weed has bright, sunflower-like yellow flowers from July-September.  It tolerates a wide range of soil, from wet to dry, and prefers full to part sun.  The pollen and nectar attract bees, bumble bees, butterflies, wasps, and the seeds are often eaten by Goldfinches.
