Corn gromwell is a low-maintenance wildflower of arable fields and disturbed ground, producing small white flowers in spring and early summer. It thrives in well-drained, sandy or loamy soils in full sun to partial shade and requires very little intervention once established. It is best suited to wildflower gardens, cottage borders, or naturalized areas where it can self-seed freely.
