One of several plants in the Silphium genus, Compass Plant combines sunflower-like flowers with uniquely shaped and textured leaves for a stunning statement wildflower. Its deeply cut and hairy leaves typically align themselves north/south to avoid noontime sun, which earned this plant its common name.
Great for naturalized prairie landscapes and pollinator gardens. One of the taller flowering plants, good for high focal point or back of a planting bed. Drought tolerant.
Care and Maintenance
Needs full sun, less tollerant of water inundation in artifical plantings. Slow growing and may need protection in the first 2 years but roots can eventually reach 15' deep.
Pest and Diseases
No major issues.
Establishment and Propagation
Propagation is very successful from seed. Because of a tough seed coat, moist, cold stratification at 33-38 degrees F for 10-60 days is beneficial. After stratification, sow seeds at a shallow depth (1/2 inch) in the spring.
Alternative Plant Selections
Illinois native statewide.
Extremely tall, coarse-looking perennial with stiff, hairy and resinous stems. d
