Heliopsis helianthoides (Smooth oxeye)
Muller, Thomas L.

Heliopsis helianthoides (L.) Sweet


Smooth oxeye, Oxeye sunflower, False sunflower

Asteraceae (Aster Family)



A common, 3-5 ft. perennial with stiff, branched stems; sunflower-like heads; and opposite, toothed leaves. Resembling a small version of a yellow sunflower with a cone-shaped central disk and opposite, toothed, simple leaves. The yellow flower heads are 2 in. across and have raised, yellow centers.

This plant looks like true sunflowers, which are in the genus Helianthus. Unlike sunflowers, its rays persist on the flower heads; the rays of sunflowers wither and fall away. It is placed in Heliopsis due to its cone-shaped central disk. Oxeye is hardy and easily grown as a showy garden perennial in dry sites and is a good choice for clay soil.
