Helenium

 

a genus of annual or perennial herbaceous plants of the family Compositae. There are about 40 species in North and Central America, primarily in the western United States. Many species are ornamentals. H. autumnale, a perennial plant with large flower heads in corymbose clusters, is used extensively in horticulture. Horticultural forms and varieties of hybrid origin are joined under the name H. hybridium. They vary in height and are distinguished by the color of their flower clusters, which are combinations of yellow, brown, and a reddish purple tint. Helenium blooms in the second half of the summer and in the autumn.
