Ox-eye daisy is an upright, clump-forming, sunflower-like perennial that persists in the garden when it can seed in freely. Daisy-like flowers bloom in summer, with yellow-orange rays surrounding brownish-yellow center cones appear. Plants in the genus Heliopsis are both similar in appearance to and closely related to those in the genus Helianthus, the true sunflower. Heliopsis is sometimes commonly called false sunflower. Easily grown in average, dry to medium, well-drained soil in full sun. Plant stems may be cut back by 1/3 to 1/2 in late May to reduce overall plant height.
