Silphium laciniatum
, Compass plant's towering eight foot stalks bear big 4 to 5 inch flowers that resemble sunflowers.  The decorative and deeply lobed two foot tall basal leaves are an attractive addition to a native wildflower garden.  Native Compass Plant's leaf surface faces the morning and afternoon sun, positioning the leaf in a north south direction (thus its name).  The taproot of this plant may grow six feet deep making the plant resistant to drought.  Compass Plant flowers are utilized by butterflies and it's large seeds consumed by song birds.  Plant Compass Plant in humus rich, well drained soil and full sun.  

Compassplant can be positioned in the middle of a perennial bed where its attractive basal leaves and flowers will become a focal point or at the back border.  Plant alone or in small groups rising above other plants.
