Hymenoxys hoopesii (A. Gray) Bierner
Owl's-claws, Orange Sneezeweed
Asteraceae (Aster Family)
Synonym(s): Dugaldia hoopesii, Helenium hoopesii
USDA Symbol: HYHO
A stout, 1 ft. perennial with large, yellow, daisy-like flowers in loose clusters. The foliage is yellow-green - large at the base, becoming reduced upward.
The round, deep yellow flower heads with rays hanging around the edge distinguish this and other plants of the genera Helenium and Hymenoxys that are commonly known as sneezeweeds. The heads of some species are much smaller, and the way their leaves are arrayed along the stem varies. The common name sneezeweed, is equally correct for Hymenoxys or Helenium species. Preparations made from the root of this plant have been used to treat rheumatic pains, stomach disorders, and, in infants, colic and diarrhea.
