Compass Plant
Silphium laciniatum
Compass Plant is renowned for its unique foliage and statuesque presence. Amazingly, the large, deeply lobed leaves actively (but very gradually) align themselves north-south to minimize sun exposure, which is how the plant gets its common name. During mid to late summer, it sends up tall flower spikes that can reach up to 9 feet, topped with bright yellow, sunflower-like blooms that attract bees, butterflies, and birds. This durable plant is ideal for naturalized areas and prairie gardens, where its deep roots help it withstand drought and provide soil stabilization.

Maintenance Tips
- Deadhead to maintain appearance and prevent excessive self-seeding.
- Division is rarely needed due to its deep taproot.
- Best propagated by collecting resowing seed, but pay attention to seedlings which may need to be policed to control spread in smaller yards or gardens.
- Stake flower stalks if necessary in windy areas to prevent leaning.
