''Helenium'' species are used as food plants by the larvae of some Lepidoptera species including ''Phymatopus, Phymatopus behrensii''. Genus level properties: most conspicuously globe-like disk-shaped flowers, rays three-lobed at tip. Species File:Helenium 'El Dorado'. Opengebarsten bloemknop. 18-07-2021.
