prairie dock

Silphium terebinthinaceum

Native to prairies, railroad right-of-ways, and other exposed habitats in the Midwest and portions of the southern United States. Huge oval to heart-shaped, dark green leaves grow up to 2′ long. From these clumps stems up to 10 feet tall rise, branching at the top and producing sunflower-like flowers up to 3″ wide in mid to late summer. The seeds provide food for songbirds.

Foliage is particularly attractive, but these plants grow deep taproots and colonize so select your site carefully!
