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.
‘Tuscan Sun’ is a dwarf oxeye cultivar that is perhaps the shortest member of the genus available in commerce today. It typically grows to only 15-20” tall. Daisy-like flowers (2” diameter) with yellow rays with orange-gold centers bloom throughout summer atop stiff stems. Plants are well-branched plants with ovate, dark green leaves.
No serious insect or disease problems. Red aphids are occasional visitors. Reportedly has some resistance to powdery mildew.
