Ox-eye is a cheerful European wildflower perennial that produces bright yellow daisy-like blooms from early summer into autumn, making it a great choice for cottage and meadow gardens. It thrives in well-drained, alkaline soils and tolerates partial shade, though it blooms most prolifically in full sun. Deadhead spent flowers to encourage continued blooming and divide clumps every few years to maintain vigor.
