Treacle mustard is a hardy, fast-growing wildflower that thrives in well-drained soils under full sun to partial shade and requires minimal watering once established. It self-seeds readily, making it a reliable addition to cottage gardens, meadow plantings, or pollinator borders. Deadhead spent flowers if you wish to control spreading, but otherwise this plant needs very little attention.
