Glaucous king-devil is a low-growing meadow perennial best suited to naturalized or wildflower garden settings. It prefers well-drained soils and part shade, requiring very little supplemental watering once established. This plant is more of a specialist wildflower than a typical garden ornamental and spreads by runners.
