Easily grown in average, dry to medium, well-drained soil in full sun. Tolerates drought, but does best if regularly watered. Tolerates a wide range of soils, including poor, infertile ones. Tolerates some light shade, but plants are less vigorous and stems need support in heavier shade. Remove spent flowers to extend bloom season. Plant stems may be cut back by 1/3 to 1/2 in late May to reduce overall plant height.

Noteworthy Characteristics

Heliopsis helianthoides, commonly called ox eye, is an upright, clump-forming, nearly glabrous, sunflower-like, short-lived perennial that is native to eastern and central North America. It typically grows to 3-4' tall and features daisy-like flowers (2-3” diameter) with yellow-orange rays surrounding brownish-yellow center cones. Flowers bloom throughout summer atop stiff stems clad with ovate, toothed leaves (to 6" long).

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.

Genus name is from Greek helios meaing sun and opsis meaning resembling.

‘Prairie Sunset’ is an oxeye cultivar that is noted for its purple stems, purple-veined foliage and reddish-maroon basal petal ring. Typically grows 3-5’ tall. Features daisy-like flowers with yellow rays and darker yellow-brown center disks. Maroon tinting at the base of the ray flowers forms a distinctive ring around the center disk. Flowers bloom from early summer to early fall atop stiff stems that seldom need staking. Serrate, ovate, dark green leaves (to 5” long) have purple veining. Good fresh cut flower.
