This cheery perennial gives back so much while needing so little maintenance. Coreopsis attracts butterflies during its long bloom season, and provides great cut flowers from spring through summer.


Sunray Coreopsis is an outstanding variety of North American native prairie plant that blooms all summer with large, golden-yellow flowers held on long stems above its dark green foliage. Tolerant of almost any soil as long as it is well drained, this mounding perennial thrives with heat and sun, and is drought-resistant. Although fairly short-lived, Coreopsis will self-seed to help perpetuate itself in the garden, and can also spread by rhizomes. This easy-to-grow plant attracts butterflies, makes great cut flowers, grows well in containers, and is rabbit- and deer-resistant. As with many perennials, Coreopsis benefits from being divided and replanted in the fall every few years. To encourage its best flowering, keep deadheading spent flowers. This compact, Great Plains native perennial works great in borders, containers, mass plantings, rock gardens, meadows, cottage gardens, and along paths.
