Silphium albiflorum

A tall perennial with rigid, deeply divided leaves. Sometimes called Compass Plant, its leaves always align in a north-south direction, exposing their large, flat surfaces to as much sun as possible. The large, white, daisy-like blooms grow up and down the sturdy stem from late spring through mid-summer. This slow-growing but extremely long-lived plant develops a tremendous taproot that can be as deep as 15 feet.
