Read about Helianthella in the Standard Cyclopedia of Horticulture
Helianthella (the plant resembles Helianthus). Compositae. Hardy perennial herbs from North America, with showy yellow heads borne in autumn. Stem commonly unbranched: lvs. mostly scattered and sessile, linear or lanceolate, entire: heads solitary or few, with yellow infertile rays and a yellow or brownish disk.—Thirteen species. Helianthella belongs to a group of genera distinguished from Helianthus by having the frs. laterally compressed instead of thick and obtusely angled. Other cult, genera of this group are Actinomeris, Encelia and Verbesina, which are distinguished from one another by combinations of fr. and pappus characters. The single species in cultivation is easily grown in a variety of soils, and is propagated by seeds or by dividing the rootstocks. The above text is from the Standard Cyclopedia of Horticulture.
