Description: Before flowering, Rosin Weed can be mistaken for Milkweed. While flowering, it resembles a Sunflower although it blooms earlier than the native Sunflowers. 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. It is aggressive though, so choose a spot where it can't overwhelm smaller plants. Rosin Weed is a wonderful choice for a native garden, especially if you are concerned with drought. When it comes to tolerating dry soils, few plants are as hardy as Rosin Weed. With its deep taproot, this species will keep its composure while other plants whither. Small rhizomes will extend from this taproot allowing it to form small colonies, albeit slowly. Rosin Weed attracts a variety of pollinators but it is especially relished by some of our smaller solitary bees. The plant gets its common name from the sticky rosin it produces.
