Oxeye is a clump-forming, upright, Missouri native perennial which occurs in open or rocky woods, thickets, prairies and along railroads throughout Missouri, except for the southeast lowlands. Typically grows 3-6' tall. Features daisy-like flowers (2-3" diameter) with yellow-orange rays and brown center disks atop stiff stems. Rough, serrate, medium green leaves (to 5" long). This species is a somewhat weedy plant that is less floriferous (and therefore less desirable as a garden plant) than the cultivars available (see H. 'Ballerina' and H. 'Summer Sun'). Lengthy summer to early fall bloom. Heliopsis is both similar in appearance to and closely related to Helianthus, the true sunflower. Good fresh cut flower.
No serious insect or disease problems. Some susceptibility to aphids. Taller plants may need staking or other support.
Provides long summer bloom for the perennial border or cutting garden. Also effective in a native plant or wild garden or as part of a naturalized planting or prairie area.
