Star-mustard is a relatively uncommon wildflower best suited to open, sunny positions in well-drained soil. It produces small yellow flowers attractive to bees and butterflies and requires little intervention once established. Deadheading spent blooms can help prolong flowering and prevent unwanted self-seeding.
