Before flowering, Rosin Weed can be mistaken for Milkweed. While flowering, it resembles a Sunflower.  It blooms earlier than most Sunflowers, though, and is not as aggressive. The deep taproot on mature plants is very drought-tolerant and small rhizomes extending from this taproot allow it to form small colonies, albeit slowly.  It may be the best Silphium choice for a garden setting due to its shorter stature, ability to mature faster, and tough stem that keeps it upright with little to no surrounding plant support.
