This plant is suitable for a formal garden, the back of a flower border or a natural area. It will be shorter in sunny, dry sites. The flowers attract a wide assortment of insect pollinators. Birds will eat the seeds. It is a host for the silphium moth. It has some deer and rabbit resistance but it is best to protect young plants.
