Description: A striking member of the silphium family. The flowers bloom to face east and west while the very large, deeply lobed basal leaves face north and south. The stalk is bristly and exudes a resin. Like all silphiums it has a deep tap root, making it very difficult to transplant-keep away from septic systems.
