Helianthus strumosus
Also called Pale Leaved Sunflower, Pale Leaf Sunflower, Rough Sunflower, Swollen Sunflower, Pale Leaved Woodland Sunflower, Rough Leaved Sunflower, Woodland Sunflower
Helianthus strumosus is a native North American perennial sunflower from woodland edges, prairies and meadows, growing 3 to 8 ft tall from rhizomes. It thrives in partial sun and moist, sandy to loamy soil, and needs a cold period to germinate.
Helianthus strumosus, the pale-leaf woodland sunflower, is a species of sunflower native to North America east of the Great Plains and is in the family Asteraceae. It is a native perennial sunflower that resembles other members of this family including the Pale Sunflower (H. decapetalus), Woodland Sunflower (H. divaricatus), Hispid Sunflower (H. hirsutus), and Jerusalem Artichoke (H. tuberosus). Pale-leaf sunflowers can be found in a diverse range of habitats including woodland areas, prairies, and meadows, providing that these habitats have access to partial sun.
Helianthus strumosus is a widely distributed in North America. It is found in the central and eastern United States, and southeastern parts of Canada. It is found more regularly in non-wetland areas, although it can occur in wetlands. The woodland sunflower is normally found in moist to moderately moist and sandy to loamy sandy areas. H. strumosus grows in natural, disturbed, and man-made habitats. The population can quickly become dense. These flowers must go through a minimum 30 day cold stratification before they are able to germinate.
The roots of H. strumosus are one of the only edible parts of the plant. They can be boiled down to make a liquor that has been used to treat adults and children with worms. The roots can also be used to make an infusion to help with lung related problems. Seeds from this sunflower can be used to make an oil for cooking and soap making.
