Compass Plant (Silphium laciniatum) is a tall and sturdy perennial with coarsely textured stems and leaves. Its basal leaves are 1' - 2' long, about half as wide, deeply lobed, and become much smaller as they go up the stem. Scattered along the upper half are 6 - 30 yellow composite flowers, and its large central taproot can go 15 feet into the ground which can allow it to live for up to 100 years. The common name refers to the belief of pioneers that its leaves often pointed in a north-south direction to avoid the heat of the mid-day sun.
