A.k.a. rosin weed. A hardy plant that matures faster than other Silphium (such as prairie dock and compass plant) and may tolerate drought even better. Flowers are just as showy as its cousins, with the bonus that rosinweed generally does not need to be staked despite its height. May form colonies, but is not particularly aggressive.
