Standard Cyclopedia of Horticulture

Heliopsis (Greek, like the sun). Compositae. Hardy herbaceous plants, bearing numerous yellow flowers in autumn.

Stem erect, loosely branching: heads yellow, long- stalked, borne in loose terminal or axillary panicles both radiate and discoid: lvs. opposite, petioled, 3- ribbed, oblong-ovate to ovate-lanceolate, coarsely toothed. Heliopsis has no pappus, while in Helianthus the pappus has 2 awns. In Heliopsis the rays have pistils, but may be fertile or sterile. In Helianthus the rays have no pistils at all.—About 10 species, all native of N. Amer. They are all perennials except one, and that is not cult. They are not common in gardens because of the more attractive forms in Helianthus. H. helianthoides Var. pitcheriana, however, deserves wider popularity. For cult., see Helianthus.
